OSX #8: Java SE 6 U5 on Mac OS X Leopard

Yesterday, Apple released Java SE version 1.6.0_05 for 64-bit Intel-based Mac OS X 10.5.2 or later. Download it here!

It's restricted to 64-bit machines and Charles is unhappy about it. Hopefully, they'll release a 32-bit version as well.

Type "sw_vers" in a terminal to check the Mac OS X version as shown below:

~ >sw_vers ProductName:    Mac OS X ProductVersion: 10.5.2 BuildVersion:   9C31

JavaOne Adrenaline - 6:40 min / mile

It must be JavaOne adrenaline - This morning I ran 2 0.75 miles with 7:03 min pace and 2 0.5 miles with 6:40 min pace.

My typical speed is 8:30 min/mile and I've never exceeded 7:30 min pace ever. So this is really cool and exciting!

TOTD #32: Rails Deployment on GlassFish v3 from NetBeans IDE

Rails powered by the GlassFish Application Server explains all the benefits of using GlassFish for developing and deploying your Rails applications. If you are using NetBeans 6.1 builds then you can deploy your Rails application directly on GlassFish v3 from within NetBeans IDE. No longer you need to have different development and deployment options.

This blog explains how to install a bleeding-edge GlassFish v3 plugin and use it to deploy your Rails app natively on GlassFish (no WAR or anything :). Let's get started! Note, this plugin is bleeding edge and will soon be released on the Beta Update Center.

1. Install "GlassFish v3 TP2" plugin in NetBeans 6.1
1. In NetBeans 6.1 IDE, go to "Tools", "Plugins" and click on "Settings". The following window is shown:
   
   
   
2. Click on "Add" and specify the URL of Bleeding Edge Update Center values as shown (copy from "http://deadlock.netbeans.org/hudson/job/javadoc-nbms/lastSuccessfulBuild/artifact/nbbuild/nbms/updates.xml.gz"):
   
   
   
   Click on "OK". The updated "Plugins" window looks like:
   
   
   
   
   Notice "Available Plugins" has changed from 58 to 140 as many more bleeding edge plugins are now available.
3. Click on "Available Plugins" and search for "GlassFish" in the top-right corner text box as shown below:
   
   
   
4. Select "GlassFish V3 JRuby Integration" and "GlassFish V3 JavaEE Integration" plugin and click on "Install" as shown below:
   
   
   
   Follow the instructions to install the plugin. The IDE needs to restart for successful plugin installation.
5. In the restarted IDE,  go to "Services" tab, right-click on "Servers" and select "Add Server...". Select "GlassFish v3 TP2" as shown below:
   
   
   
6. Select "Next >", accept the license agreement and click on "Download V3 Now..."
   
   
   
   Click on "Download V3 Now...". This downloads the latest GlassFish v3 TP2 build and installs in "/Users/arungupta/GlassFish_V3_TP2" directory. This is only an interim build, final TP2 build will be available soon! The following screen is shown once GlassFish v3 is installed:
   
   
   
   Click on "Finish". In 58 seconds, you downloaded and installed the entire GlassFish v3 app server, cool isn't it!
2. Create a Rails app and deploy on GlassFish V3
1. In NetBeans IDE, in the "Projects" tab, right-click and select "New Project...". Select "Ruby" in "Categories" and "Ruby on Rails Applications" in "Projects" as shown:
   
   
   
   Click on "Next".
2. Now comes the cool part. Enter the application name and select the recently installed GlassFish v3 as shown:
   
   
   
   This is a brand new feature in the "GlassFish v3 TP2" plugin available only on "Bleeding Edge" Update Center. It'll soon replace the default GlassFish v3 plugin from the Beta Update Center.
   
   Click on "Finish" to take all other defaults.
3. On the newly created project, right-click and select "Run" as shown:
   
   
4. The default browser page "http://localhost:8080/" shows up. Change the URL to "http://localhost:8080/HelloRails" and the following page shows up:

Roses from Frontyard - Digital Pictures

A rose, not only by any name, but in any shape or color will smell as sweet and also look as beautiful :)

Here are some pictures of roses from my front yard. The pictures were taken around 7pm yesterday and purposely shown in 640 x 480 size in order to provide visual pleasure! I've higher resolution pictures available as well, in case you are interested.

All the pictures below keep the flower in center of the frame. I'll try another set next week with Rule of Thirds.

TOTD #31: CRUD Application using Grails - Hosted on GlassFish and MySQL

TOTD #30 explained how to create CRUD application using Grails and hosted using in-built Jetty servlet engine and in-memory HSQLDB database. Jetty and HSQLDB are built into Grails and allows to start easily. You can also use GlassFish and MySQL for deploying your applications in production environment.

This blog entry walks you through the steps of deploying a Grails application on GlassFish and MySQL.

1. If MySQL is already installed, then download GlassFish v2 UR1. Otherwise you can also Download GlassFish v2 UR1 and MySQL co-bundle from usual Download Page (instructions).
2. Configure MySQL database
1. Download MySQL Connector/J 5.1.6 from here.
2. Extract the bundle and copy "mysql-connector-java-5.1.6-bin.jar" to the "lib" directory of Grails application.
3. Start MySQL database as:
   
   

   ~/testbed/grails-1.0.2/samples/crud >sudo /usr/local/mysql/bin/mysqld_safe --user root --console Starting mysqld daemon with databases from /usr/local/mysql/data

4. Create database by giving the following command:
   
   

   ~/testbed/grails-1.0.2/samples/crud >/usr/local/mysql/bin/mysqladmin create crudProd --user root

3. Configure the Application
1. Edit "grails-app/conf/DataSource.groovy" to specify MySQL configuration. The updated file looks like (changes highlighted in bold):
   
   

   dataSource {         pooled = false         driverClassName = "com.mysql.jdbc.Driver"         username = "root"         password = ""         dialect = "org.hibernate.dialect.MySQL5InnoDBDialect" } hibernate {     cache.use_second_level_cache=true     cache.use_query_cache=true     cache.provider_class='org.hibernate.cache.EhCacheProvider' } // environment specific settings environments {         development {                 dataSource {                         dbCreate = "create-drop" // one of 'create', 'create-drop','update'                         url = "jdbc:hsqldb:mem:devDB"                 }         }         test {                 dataSource {                         dbCreate = "update"                         url = "jdbc:hsqldb:mem:testDb"                 }         }         production {                 dataSource {                         dbCreate = "update"                         url = "jdbc:mysql://localhost/crudProd"                 }         } }


Being in production, it's recommended to use InnoDB tables instead of MyISAM tables. This can be easily specified by using the dialect as explained here. More details about the contents of "DataSource.groovy" can be found here.

2. Create a WAR by giving the following command:
   
   

   ~/testbed/grails-1.0.2/samples/crud >grails war Welcome to Grails 1.0.2 - http://grails.org/ Licensed under Apache Standard License 2.0 Grails home is set to: /Users/arungupta/testbed/grails-1.0.2 Base Directory: /Users/arungupta/testbed/grails-1.0.2/samples/crud Note: No plugin scripts found Running script /Users/arungupta/testbed/grails-1.0.2/scripts/War.groovy Environment set to production    [delete] Deleting: /Users/arungupta/.grails/1.0.2/projects/crud/resources/web.xml    [delete] Deleting directory /Users/arungupta/.grails/1.0.2/projects/crud/classes . . . [propertyfile] Updating property file: /Users/arungupta/testbed/grails-1.0.2/samples/crud/staging/WEB-INF/classes/application.properties     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/crud/staging/WEB-INF/plugins      [copy] Warning: /Users/arungupta/testbed/grails-1.0.2/samples/crud/plugins not found.       [jar] Building jar: /Users/arungupta/testbed/grails-1.0.2/samples/crud/crud-0.1.war    [delete] Deleting directory /Users/arungupta/testbed/grails-1.0.2/samples/crud/staging Done creating WAR /Users/arungupta/testbed/grails-1.0.2/samples/crud/crud-0.1.war

4. Deploy the WAR file as:
   
   

   ~/testbed/grails-1.0.2/samples/crud >~/testbed/glassfish/v3/p2b9/glassfish/bin/asadmin deploy crud-0.1.war crud-0.1 deployed successfully Command deploy executed successfully.

   
   The application is now accessible at "http://localhost:8080/crud-0.1" and looks like:
   
   
   
5. READ - Click on "StateController" and the following page is shown:
   
   
6. CREATE - Click on "New State" and enter the values as shown below:
   
   
   
   and click on "Create" to see the following page:
   
   
7. UPDATE & DELETE - You can click on "Edit" or "Delete" to perform U or D of CRUD or click on "State List" to view the updated list.

Please leave suggestions on other TOTD that you'd like to see. A complete archive is available here.

TOTD #30: CRUD Application using Grails - Hosted on Jetty and HSQLDB

After a simple Grails application, let's create a CRUD application. Such an application allows to perform basic database operations to read table rows from the database, create new rows, and edit and delete existing rows. This blog shows how such an application can be created using Grails, hosted on built-in Jetty servlet engine and use in-memory HSQLDB database for persistence.

A follow-up entry will show how this application can be deployed in production mode on GlassFish and using MySQL database.

1. Create a Grails application
1. After Grails download and configuration, create a new application "crud" as:
   
   

   ~/testbed/grails-1.0.2/samples >grails create-app crud Welcome to Grails 1.0.2 - http://grails.org/ Licensed under Apache Standard License 2.0 Grails home is set to: /Users/arungupta/testbed/grails-1.0.2 Base Directory: /Users/arungupta/testbed/grails-1.0.2/samples Note: No plugin scripts found Running script /Users/arungupta/testbed/grails-1.0.2/scripts/CreateApp.groovy Environment set to development     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/crud/src     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/crud/src/java     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/crud/src/groovy     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/crud/grails-app     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/crud/grails-app/controllers     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/crud/grails-app/services     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/crud/grails-app/domain     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/crud/grails-app/taglib     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/crud/grails-app/utils     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/crud/grails-app/views     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/crud/grails-app/views/layouts     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/crud/grails-app/i18n     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/crud/grails-app/conf     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/crud/test     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/crud/test/unit     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/crud/test/integration     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/crud/scripts     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/crud/web-app     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/crud/web-app/js     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/crud/web-app/css     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/crud/web-app/images     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/crud/web-app/META-INF     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/crud/lib     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/crud/grails-app/conf/spring     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/crud/grails-app/conf/hibernate [propertyfile] Creating new property file: /Users/arungupta/testbed/grails-1.0.2/samples/crud/application.properties      [copy] Copying 2 files to /Users/arungupta/testbed/grails-1.0.2/samples/crud      [copy] Copying 2 files to /Users/arungupta/testbed/grails-1.0.2/samples/crud/web-app/WEB-INF      [copy] Copying 5 files to /Users/arungupta/testbed/grails-1.0.2/samples/crud/web-app/WEB-INF/tld      [copy] Copying 87 files to /Users/arungupta/testbed/grails-1.0.2/samples/crud/web-app      [copy] Copying 17 files to /Users/arungupta/testbed/grails-1.0.2/samples/crud/grails-app      [copy] Copying 1 file to /Users/arungupta/testbed/grails-1.0.2/samples/crud      [copy] Copying 1 file to /Users/arungupta/testbed/grails-1.0.2/samples/crud      [copy] Copying 1 file to /Users/arungupta/testbed/grails-1.0.2/samples/crud [propertyfile] Updating property file: /Users/arungupta/testbed/grails-1.0.2/samples/crud/application.properties Created Grails Application at /Users/arungupta/testbed/grails-1.0.2/samples/crud

2. In your project directory, create a domain class as:
   
   

   ~/testbed/grails-1.0.2/samples/crud >grails create-domain-class state Welcome to Grails 1.0.2 - http://grails.org/ Licensed under Apache Standard License 2.0 Grails home is set to: /Users/arungupta/testbed/grails-1.0.2 Base Directory: /Users/arungupta/testbed/grails-1.0.2/samples/crud Note: No plugin scripts found Running script /Users/arungupta/testbed/grails-1.0.2/scripts/CreateDomainClass.groovy Environment set to development      [copy] Copying 1 file to /Users/arungupta/testbed/grails-1.0.2/samples/crud/grails-app/domain Created  for State      [copy] Copying 1 file to /Users/arungupta/testbed/grails-1.0.2/samples/crud/test/integration Created Tests for State

   
   This creates "State.groovy" class in "grails-app/domain" directory and looks like:
   
   

   class State { }

   
   Add two fields to store state name and the corresponding abbreviation as shown below:
   
   

   class State {         String name         String abbrev }

3. Change "grails-app/conf/BootStrap.groovy" class to initialize the domain with sample data as shown below:
   
   

   class BootStrap {      def init = { servletContext ->           new State(name:"California", abbrev:"CA").save()           new State(name:"New York", abbrev:"NY").save()           new State(name:"Texas", abbrev:"TX").save()           new State(name:"Wisconsin", abbrev:"WI").save()      }      def destroy = {      } }

4. Create a new controller as:
   
   

   ~/testbed/grails-1.0.2/samples/crud >grails create-controller state Welcome to Grails 1.0.2 - http://grails.org/ Licensed under Apache Standard License 2.0 Grails home is set to: /Users/arungupta/testbed/grails-1.0.2 Base Directory: /Users/arungupta/testbed/grails-1.0.2/samples/crud Note: No plugin scripts found Running script /Users/arungupta/testbed/grails-1.0.2/scripts/CreateController.groovy Environment set to development      [copy] Copying 1 file to /Users/arungupta/testbed/grails-1.0.2/samples/crud/grails-app/controllers Created Controller for State     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/crud/grails-app/views/state      [copy] Copying 1 file to /Users/arungupta/testbed/grails-1.0.2/samples/crud/test/integration Created ControllerTests for State

   
   This generates "grails-app/controllers/StateController.groovy" with the following content:
   
   

   class StateController {     def index = { } }

   
   Replace it with to define a scaffold:
   
   

   class StateController {     def scaffold = State }

2. Start the application using built-in Jetty Servlet engine and in-memory HSQLDB database as shown below:
   
   

   ~/testbed/grails-1.0.2/samples/crud >grails run-app Welcome to Grails 1.0.2 - http://grails.org/ Licensed under Apache Standard License 2.0 Grails home is set to: /Users/arungupta/testbed/grails-1.0.2 Base Directory: /Users/arungupta/testbed/grails-1.0.2/samples/crud Note: No plugin scripts found Running script /Users/arungupta/testbed/grails-1.0.2/scripts/RunApp.groovy Environment set to development Running Grails application.. 2008-04-18 17:26:29.962::INFO:  Logging to STDERR via org.mortbay.log.StdErrLog 2008-04-18 17:26:29.075::INFO:  jetty-6.1.4 2008-04-18 17:26:29.155::INFO:  No Transaction manager found - if your webapp requires one, please configure one. 2008-04-18 17:26:30.886:/crud:INFO:  Set web app root system property: 'crud' = [/Users/arungupta/testbed/grails-1.0.2/samples/crud/web-app/] 2008-04-18 17:26:30.886:/crud:INFO:  Initializing Log4J from [file:/Users/arungupta/.grails/1.0.2/projects/crud/resources/log4j.properties] 2008-04-18 17:26:30.945:/crud:INFO:  Initializing Spring root WebApplicationContext [0] spring.GrailsWebApplicationContext Refreshing org.codehaus.groovy.grails.commons.spring.GrailsWebApplicationContext@848dfb: display name [org.codehaus.groovy.grails.commons.spring.GrailsWebApplicationContext@848dfb]; startup date [Fri Apr 18 17:26:32 PDT 2008]; parent: org.springframework.web.context.support.XmlWebApplicationContext@cddcc3 [1] spring.GrailsWebApplicationContext Bean factory for application context [org.codehaus.groovy.grails.commons.spring.GrailsWebApplicationContext@848dfb]: org.springframework.beans.factory.support.DefaultListableBeanFactory@11f136 2008-04-18 17:26:34.655:/crud:INFO:  Initializing Spring FrameworkServlet 'grails' 2008-04-18 17:26:35.716::INFO:  Started SelectChannelConnector@0.0.0.0:8080 Server running.

GlassFish @ Silicon Valley Web Developer JUG - Tomorrow (Apr 15, 2008)

Project GlassFish: On a mission to please Developers is the topic of talk at Silicon Valley Web Developer JUG tomorrow (Apr 15, 2008). Hear all about GlassFish v2, it's exciting set of features such as Metro, High Availability, Clustering, Grizzly, Scripting, SIP container, Tools integration (such as NetBeans and Eclipse) and many others that together deliver a compact and high-fidelity Java EE Application server. You'll also learn about GlassFish v3 and how, through modularization and embedability, it enables support for non-Java EE containers such as Rails, Phobos and others.

Rails and Java EE integration - Native Rails on GlassFish v3

The last part of this tri-series blog (Part 1, Part 2) will show how a Rails application can be deployed on GlassFish - without the need of Goldspike, Warbler or any other gem or plugin. Yes, that's a native Rails app deployment on GlassFish v3.

GlassFish v3 is next version of GlassFish v2 and the focus is modularization, enablement of non-Java EE containers and modularity - download b09.

Rails powered by GlassFish provides all the details on why GlassFish provides an industry-grade and functionally-rich Application Server.

Now detailed steps:

1. Using JRuby 1.1 (installed with Rails), create a Rails app "railsee3" as:
   
   

   ~/testbed/jruby-1.1/samples/rails >../../bin/jruby -S rails railsee3       create        create  app/controllers       create  app/helpers       create  app/models       . . .       create  log/production.log       create  log/development.log       create  log/test.log

2. Add Servlet descriptors
1. Create a new directory "WEB-INF", and a new file "web.xml" in that directory using the following contents:
   
   

   <!DOCTYPE web-app PUBLIC   "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"   "http://java.sun.com/dtd/web-app_2_3.dtd"> <web-app>         <servlet>                 <servlet-name>HelloServlet</servlet-name>                 <servlet-class>server.HelloServlet</servlet-class>         </servlet>         <servlet-mapping>                 <servlet-name>HelloServlet</servlet-name>                 <url-pattern>/hello</url-pattern>         </servlet-mapping> </web-app>

2. Create a new file "sun-web.xml" in "WEB-INF" using the following contents:
   
   

   <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE sun-web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Application Server 9.0 Servlet 2.5//EN" "http://www.sun.com/software /appserver/dtds/sun-web-app_2_5-0.dtd"> <sun-web-app error-url="">   <context-root>/servlet</context-root>   <class-loader delegate="true"/> </sun-web-app>

3. Create a new directory "WEB-INF/lib".
3. Create and Copy Servlet
1. Create a Java library with Servlet code as explained in bullet #5 here.
2. Copy "HelloServlet.jar" from "dist" directory of NetBeans project to "WEB-INF/lib" directory.
4. Configure JRuby-on-Rails in GlassFish - Edit "config/asenv.conf" in GlassFish directory and specify JRUBY_HOME as the last line:
   
   

   JRUBY_HOME="/Users/arungupta/testbed/jruby-1.1"

   
   
5. Deploy the Rails application as:



~/testbed/jruby-1.1/samples/rails >~/testbed/glassfish/v3/p2b9/glassfish/bin/asadmin deploy --force=true railsee3 railsee3 deployed successfully Command deploy executed successfully.

6. The bundled Servlet is now accessible at "http://localhost:8080/servlet/hello". The default browser output looks like:
   
   
   
   And passing a parameter to the URL as "http://localhost:8080/railsee3/hello?name=Arun" shows the output as:
   
   
   

7. Create a new Controller and View as
   
   

   ~/testbed/jruby-1.1/samples/rails/railsee3 >../../../bin/jruby script/generate controller home index JRuby limited openssl loaded. gem install jruby-openssl for full support. http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL       exists  app/controllers/       exists  app/helpers/       create  app/views/home       exists  test/functional/       create  app/controllers/home_controller.rb       create  test/functional/home_controller_test.rb       create  app/helpers/home_helper.rb       create  app/views/home/index.html.erb

8. Change the generated controller in "app/controllers/home_controller.rb" to:
   
   

   class HomeController < ApplicationController include Java   def index         url = java.net.URL.new("http://localhost:8080/servlet/hello");         conn = url.open_connection;         reader = java.io.BufferedReader.new(java.io.InputStreamReader.new(conn.get_input_stream));         @servlet_output = "";         input_line = reader.read_line;         while input_line != nil                 @servlet_output << input_line;                 input_line = reader.read_line;         end         reader.close;   end end

9. Change the generated view in "app/views/home/index.rhtml.erb" to:
   
   

   <h1>Home#index</h1> <p>Find me in app/views/home/index.html.erb</p> <%= @servlet_output %>

10. Re-deploy the Rails application as shown in bullet # 5 above and "http://localhost:8080/railsee3/home/index" shows the output as shown:
    
    

• Part 1- WAR-based deployment on GlassFish v2 UR1 using Goldspike
• Part 2 - WAR-based deployment on GlassFish v2 UR1 using Warbler
• Part 3 - Native deployment on GlassFish v3 without any additional gems or plugins

Getting Started with Grails on GlassFish

This blog has published good amount of content on how Ruby-on-Rails applications can be deployed on GlassFish. Grails is another popular MVC-based framework that leverages the Groovy language. Basically, Grails : Groovy :: Rails : Ruby.

Starting today, I plan to start publishing content on Grails and talk about how GlassFish v3 is turning out to be a home for several scripting languages - Ruby/JRuby/Rails, JavaScript/Phobos, Groovy/Grails and more to be added.

This blog shows how to get started with Grails and deploy a simple application on GlassFish v3. Lets go!

1. Download Grails 1.0.2 (docs, release notes, other builds) and unzip.
   
   

   ~/testbed/grails-1.0.2 >export GRAILS_HOME=`pwd` ~/testbed/grails-1.0.2 >export PATH=$GRAILS_HOME/bin:$PATH

   
   On MacOS 10.5, I had to manually set the executable permissions using "chmod +x grails" and then saw the following:
   
   

   ~/testbed/grails-1.0.2 >grails Welcome to Grails 1.0.2 - http://grails.org/ Licensed under Apache Standard License 2.0 Grails home is set to: /Users/arungupta/testbed/grails-1.0.2 No script name specified. Use 'grails help' for more info

   
   
2. Create & Deploy a Grails HelloWorld:
1. Create a Grails app "helloworld" as:
   
   

   ~/testbed/grails-1.0.2/samples >grails create-app helloworld Welcome to Grails 1.0.2 - http://grails.org/ Licensed under Apache Standard License 2.0 Grails home is set to: /Users/arungupta/testbed/grails-1.0.2 Base Directory: /Users/arungupta/testbed/grails-1.0.2/samples Note: No plugin scripts found Running script /Users/arungupta/testbed/grails-1.0.2/scripts/CreateApp.groovy Environment set to development     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/src     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/src/java     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/src/groovy     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/grails-app     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/grails-app/controllers     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/grails-app/services     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/grails-app/domain     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/grails-app/taglib     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/grails-app/utils     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/grails-app/views     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/grails-app/views/layouts     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/grails-app/i18n     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/grails-app/conf     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/test     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/test/unit     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/test/integration     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/scripts     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/web-app     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/web-app/js     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/web-app/css     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/web-app/images     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/web-app/META-INF     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/lib     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/grails-app/conf/spring     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/grails-app/conf/hibernate [propertyfile] Creating new property file: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/application.properties      [copy] Copying 2 files to /Users/arungupta/testbed/grails-1.0.2/samples/helloworld      [copy] Copying 2 files to /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/web-app/WEB-INF      [copy] Copying 5 files to /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/web-app/WEB-INF/tld      [copy] Copying 87 files to /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/web-app      [copy] Copying 17 files to /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/grails-app      [copy] Copying 1 file to /Users/arungupta/testbed/grails-1.0.2/samples/helloworld      [copy] Copying 1 file to /Users/arungupta/testbed/grails-1.0.2/samples/helloworld      [copy] Copying 1 file to /Users/arungupta/testbed/grails-1.0.2/samples/helloworld [propertyfile] Updating property file: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/application.properties Created Grails Application at /Users/arungupta/testbed/grails-1.0.2/samples/helloworld

   This directory is created using Convention over Configuation and the purpose of each directory is explained here.
   
2. The app can be started as:
   
   

   ~/testbed/grails-1.0.2/samples/helloworld >grails run-app Welcome to Grails 1.0.2 - http://grails.org/ Licensed under Apache Standard License 2.0 Grails home is set to: /Users/arungupta/testbed/grails-1.0.2 Base Directory: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld Note: No plugin scripts found Running script /Users/arungupta/testbed/grails-1.0.2/scripts/RunApp.groovy Environment set to development     [mkdir] Created dir: /Users/arungupta/.grails/1.0.2/projects/helloworld/classes   [groovyc] Compiling 6 source files to /Users/arungupta/.grails/1.0.2/projects/helloworld/classes     [mkdir] Created dir: /Users/arungupta/.grails/1.0.2/projects/helloworld/resources/grails-app/i18n [native2ascii] Converting 10 files from /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/grails-app/i18n to /Users/arungupta/.grails/1.0.2/projects/helloworld/resources/grails-app/i18n      [copy] Copying 1 file to /Users/arungupta/.grails/1.0.2/projects/helloworld/classes      [copy] Copying 1 file to /Users/arungupta/.grails/1.0.2/projects/helloworld/resources      [copy] Copying 1 file to /Users/arungupta/.grails/1.0.2/projects/helloworld Running Grails application.. 2008-04-10 10:47:51.501::INFO:  Logging to STDERR via org.mortbay.log.StdErrLog 2008-04-10 10:47:51.603::INFO:  jetty-6.1.4 2008-04-10 10:47:51.755::INFO:  No Transaction manager found - if your webapp requires one, please configure one. 2008-04-10 10:47:52.503:/helloworld:INFO:  Set web app root system property: 'helloworld' = [/Users/arungupta/testbed/grails-1.0.2/samples/helloworld/web-app/] 2008-04-10 10:47:52.503:/helloworld:INFO:  Initializing Log4J from [file:/Users/arungupta/.grails/1.0.2/projects/helloworld/resources/log4j.properties] 2008-04-10 10:47:52.582:/helloworld:INFO:  Initializing Spring root WebApplicationContext [0] spring.GrailsWebApplicationContext Refreshing org.codehaus.groovy.grails.commons.spring.GrailsWebApplicationContext@dccb42: display name [org.codehaus.groovy.grails.commons.spring.GrailsWebApplicationContext@dccb42]; startup date [Thu Apr 10 10:47:53 PDT 2008]; parent: org.springframework.web.context.support.XmlWebApplicationContext@188af2 [0] spring.GrailsWebApplicationContext Bean factory for application context [org.codehaus.groovy.grails.commons.spring.GrailsWebApplicationContext@dccb42]: org.springframework.beans.factory.support.DefaultListableBeanFactory@413ebc 2008-04-10 10:47:55.602:/helloworld:INFO:  Initializing Spring FrameworkServlet 'grails' 2008-04-10 10:47:55.652::INFO:  Started SelectChannelConnector@0.0.0.0:8080 Server running.

   The output in the browser looks like:
   
   
   Jetty is used as the development environment server but soon GlassFish v3 can be used, stay tuned on that!
   
   Anyway, the WAR format is used for deployment. Lets see how this app can be easily deployed as a WAR file on GlassFish v3.
   
3. Download GlassFish v3 Preview 2 b08 and unzip.
4. Create and Deploy WAR
1. GlassFish certainly supports WAR-based deployment of Grails apps but direct deployment (aka native or directory-based deployment) of Grails applications will be supported soon as well. Anyway, for now, create a WAR file of the application as:
   
   

   ~/testbed/grails-1.0.2/samples/helloworld >grails war Welcome to Grails 1.0.2 - http://grails.org/ Licensed under Apache Standard License 2.0 Grails home is set to: /Users/arungupta/testbed/grails-1.0.2 Base Directory: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld Note: No plugin scripts found Running script /Users/arungupta/testbed/grails-1.0.2/scripts/War.groovy Environment set to production    [delete] Deleting: /Users/arungupta/.grails/1.0.2/projects/helloworld/resources/web.xml    [delete] Deleting directory /Users/arungupta/.grails/1.0.2/projects/helloworld/classes    [delete] Deleting directory /Users/arungupta/.grails/1.0.2/projects/helloworld/resources     [mkdir] Created dir: /Users/arungupta/.grails/1.0.2/projects/helloworld/classes   [groovyc] Compiling 6 source files to /Users/arungupta/.grails/1.0.2/projects/helloworld/classes     [mkdir] Created dir: /Users/arungupta/.grails/1.0.2/projects/helloworld/resources/grails-app/i18n [native2ascii] Converting 10 files from /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/grails-app/i18n to /Users/arungupta/.grails/1.0.2/projects/helloworld/resources/grails-app/i18n      [copy] Copying 1 file to /Users/arungupta/.grails/1.0.2/projects/helloworld/classes      [copy] Copying 1 file to /Users/arungupta/.grails/1.0.2/projects/helloworld/resources     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/staging      [copy] Copying 93 files to /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/staging      [copy] Copied 19 empty directories to 1 empty directory under /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/staging      [copy] Copying 12 files to /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/staging/WEB-INF/grails-app      [copy] Copying 26 files to /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/staging/WEB-INF/classes     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/staging/WEB-INF/spring      [copy] Copying 1 file to /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/staging/WEB-INF/classes     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/staging/WEB-INF/templates/scaffolding      [copy] Copying 6 files to /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/staging/WEB-INF/templates/scaffolding      [copy] Copying 49 files to /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/staging/WEB-INF/lib      [copy] Copying 1 file to /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/staging/WEB-INF    [delete] Deleting: /Users/arungupta/.grails/1.0.2/projects/helloworld/resources/web.xml      [copy] Warning: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/plugins not found.

   The create WAR file is 18,012,069 bytes.
   
2. Start the GlassFish container as:
   
   

   ~/testbed/glassfish/v3/p2-b08/glassfish >bin/startserv --verbose Apr 10, 2008 11:03:28 AM com.sun.enterprise.admin.launcher.GFLauncherLogger info INFO: JVM invocation command line: /System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Home/bin/java -cp /Users/arungupta/testbed/glassfish/v3/p2-b08/glassfish/modules/glassfish-10.0-SNAPSHOT.jar . . .

3. Deploy the WAR file as:
   
   

   ~/testbed/grails-1.0.2/samples/helloworld >~/testbed/glassfish/v3/p2-b08/glassfish/bin/asadmin deploy helloworld-0.1.war helloworld-0.1 deployed successfully properties=(name=helloworld-0.1) Command deploy executed successfully.

   
   The output in the browser now looks like:
   
   
   
5. Add Controller and Re-deploy
1. Create a new controller as:
   
   

   C~/testbed/grails-1.0.2/samples/helloworld >grails create-controller hello Welcome to Grails 1.0.2 - http://grails.org/ Licensed under Apache Standard License 2.0 Grails home is set to: /Users/arungupta/testbed/grails-1.0.2 Base Directory: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld Note: No plugin scripts found Running script /Users/arungupta/testbed/grails-1.0.2/scripts/CreateController.groovy Environment set to development      [copy] Copying 1 file to /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/grails-app/controllers Created Controller for Hello     [mkdir] Created dir: /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/grails-app/views/hello      [copy] Copying 1 file to /Users/arungupta/testbed/grails-1.0.2/samples/helloworld/test/integration Created ControllerTests for Hello

   
   and change the controller as shown:
   
   

   ~/testbed/grails-1.0.2/samples/helloworld >vi grails-app/controllers/HelloController.groovy class HelloController {        def world = {                 render "Hello World!"         }     //def index = { } }

2. Re-create & re-deploy the WAR as described in bullet # 4. And now "http://localhost:8080/helloworld-0.1" shows the output as shown:
   
   
   
   and clicking on "HelloController" shows the output as:
   
   
   
   The same view is also available at "http://localhost:8080/helloworld-0.1/hello/world" as shown below:
   
   
   

• Deploy Grails app on GlassFish v3 using "grails" command (in development environment)
• Deploy Grails app directly on GlassFish v3 without creating a WAR (in production environment)
• Seamless integration with NetBeans to provide direct development/deployment to GlassFish
