TOTD # 77: Running Seam examples with GlassFish

Seam is a full-stack solution to assemble complex web applications using simple annotated classes, a rich set of UI components, and very little XML. It integrates Ajax and Business Process Modeling with several Java EE technologies such as Java Server Faces (JSF), Java Persistence API (JPA), and Enterprise Java Beans (EJB 3.0).

1. Download Seam 2.1.1 GA from here and unzip.
2. Build "examples/jpa" sample as:
   
   

   ~/tools/jboss-seam-2.1.1.GA/examples/jpa >ant glassfish Buildfile: build.xml glassfish: initcopy: initpoms:      [echo] Setting up dependencies     [mkdir] Created dir: /Users/arungupta/tools/jboss-seam-2.1.1.GA/classes/poms      [copy] Copying 1 file to /Users/arungupta/tools/jboss-seam-2.1.1.GA/classes/poms [artifact:install] [INFO] Installing /Users/arungupta/tools/jboss-seam-2.1.1.GA/classes/poms/root.pom to . . . . . . init.war: war:      [copy] Copying 27 files to /Users/arungupta/tools/jboss-seam-2.1.1.GA/examples/jpa/exploded-archives-glassfish/jboss-seam-jpa.war      [copy] Copying 7 files to /Users/arungupta/tools/jboss-seam-2.1.1.GA/examples/jpa/exploded-archives-glassfish/jboss-seam-jpa.war/WEB-INF/lib noejb.war:      [copy] Copying 18 files to /Users/arungupta/tools/jboss-seam-2.1.1.GA/examples/jpa/exploded-archives-glassfish/jboss-seam-jpa.war/WEB-INF/lib      [copy] Copying 2 files to /Users/arungupta/tools/jboss-seam-2.1.1.GA/examples/jpa/exploded-archives-glassfish/jboss-seam-jpa.war      [copy] Copying 4 files to /Users/arungupta/tools/jboss-seam-2.1.1.GA/examples/jpa/exploded-archives-glassfish/jboss-seam-jpa.war distributable.war: noejb.archive:       [jar] Building jar: /Users/arungupta/tools/jboss-seam-2.1.1.GA/examples/jpa/dist-glassfish/jboss-seam-jpa.war BUILD SUCCESSFUL Total time: 5 seconds

3. Deploy the sample as:
   
   

   ~/tools/jboss-seam-2.1.1.GA/examples/jpa >~/tools/glassfish/v2.1/glassfish/bin/asadmin deploy dist-glassfish/jboss-seam-jpa.war Command deploy executed successfully.

   
   The app is now accessible at "http://localhost:8080/jboss-seam-jpa" and here are some of the captured screenshots:
   
   
   
   
   
   
   
   Simple and easy!
   
4. Build "examples/hibernate" as:
   
   

   ~/tools/jboss-seam-2.1.1.GA/examples/hibernate >ant glassfish Buildfile: build.xml glassfish: initcopy: initpoms:      [echo] Setting up dependencies      [copy] Copying 1 file to /Users/arungupta/tools/jboss-seam-2.1.1.GA/classes/poms [artifact:install] [INFO] Installing /Users/arungupta/tools/jboss-seam-2.1.1.GA/classes/poms/root.pom to /Users/arungupta/.m2/repository/org/jboss/seam/root/2.1.1.GA/root-2.1.1.GA.pom  . . . distributable.war: noejb.archive:       [jar] Building jar: /Users/arungupta/tools/jboss-seam-2.1.1.GA/examples/hibernate/dist-glassfish/jboss-seam-hibernate.war BUILD SUCCESSFUL Total time: 6 seconds

   
   
5. Deploy the sample as:
   
   

   ~/tools/jboss-seam-2.1.1.GA/examples/hibernate >~/tools/glassfish/v2.1/glassfish/bin/asadmin deploy dist-glassfish/jboss-seam-hibernate.war Command deploy executed successfully.

   
   The app is now accessible at "http://localhost:8080/jboss-seam-hibernate" and has exactly similar snapshots as shown in "jboss-seam-jpa" sample. Simple and easy, yet again!
   
6. Build "examples/jee5/booking" and deploy as:
   
   

   ~/tools/jboss-seam-2.1.1.GA/examples/jee5/booking >ant Buildfile: build.xml initcopy: initpoms:      [echo] Setting up dependencies      [copy] Copying 1 file to /Users/arungupta/tools/jboss-seam-2.1.1.GA/classes/poms [artifact:install] [INFO] Installing /Users/arungupta/tools/jboss-seam-2.1.1.GA/classes/poms/root.pom to /Users/arungupta/.m2/repository/org/jboss/seam/root/2.1.1.GA/root-2.1.1.GA.pom      [copy] Copying 1 file to /Users/arungupta/tools/jboss-seam-2.1.1.GA/classes/poms . . . archive:       [jar] Building jar: /Users/arungupta/tools/jboss-seam-2.1.1.GA/examples/jee5/booking/dist/jboss-seam-jee5-booking.jar       [jar] Building jar: /Users/arungupta/tools/jboss-seam-2.1.1.GA/examples/jee5/booking/dist/jboss-seam-jee5-booking.war       [jar] Building jar: /Users/arungupta/tools/jboss-seam-2.1.1.GA/examples/jee5/booking/dist/jboss-seam-jee5-booking.ear BUILD SUCCESSFUL Total time: 5 seconds ~/tools/jboss-seam-2.1.1.GA/examples/jee5/booking >~/tools/glassfish/v2.1/glassfish/bin/asadmin deploy dist/jboss-seam-jee5-booking.ear Command deploy executed successfully.

   
   The application is now accessible at "http://localhost:8080/seam-jee5-booking". Wow, that's simple and easy as well!

• Chapter 39 of the Seam Community Documentation even describes how to deploy an application created using seam-gen on GlassFish.
• Dan Allen, the author of Manning's Seam in Action, presented a webinar at TheAquarium Online.
• Several other Seam entries @ TA.
• Deploying a seam-gen project to GlassFish (blog entry) - Here is a quote from the blog:
  
  GlassFish has a very sexy administrative console, but it also has a very sexy commandline tool known as asadmin. The asadmin tool gives you virtually unbounded control over the application server, including core tasks such as starting and stopping the application server, deploying and undeploying applications, and setting up database connection pools, amidst a plethora of other controls. You'll see that my modified seam-gen tool takes advantage of a handful of these commands.
  
  And another one ...
  
  GlassFish gives you efficiency through automation, which is undoubtedly the most effective way to become efficient. ... GlassFish volunteers itself to participate in a script and is the reason why I choose it as my preferred application server.
• GlassFish support added to seam-gen: It is certainly exciting to know that there are targets like "gf-deploy-datasource", "gf-deploy-hibernate", and "gf-prepare" available to Seam developers out-of-the-box.

TOTD #69: GlassFish High Availability/Clustering using Sun Web Server + Load Balancer Plugin on Windows Vista

TOTD #67 shows how to configure GlassFish High Availability using Apache httpd + mod_jk on Mac OS X. Even though that's a standard and supported configuration, there are several advantages for replacing Apache httpd with Sun Web Server and mod_jk with Load Balancer plugin that comes with GlassFish.

This Tip Of The Day (TOTD) shows how to configure Clustering and Load Balancing using GlassFish v2.1, Sun Web Server, Load Balancer plugin on Windows Vista. This blog is using JDK 6 U7, GlassFish v2.1 (cluster profile), Sun Web Server 7 U4, and Load Balancer plug-in with Sun GlassFish Enterprise Server 2.1 Enterprise Profile (with HADB link).

Lets get started!

1. Install the required software
1. Download JDK (if not already installed).
2. Download and Install GlassFish v2.1. Make sure to configure using "ant -f setup-cluster.xml". This will ensure that the created domain is capable of creating clusters and can perform in-memory session replication for applications deployed on the cluster.
3. Download and Install Sun Web Server. The process is very simple by unzipping the downloaded bundle, clicking on "setup.exe" and taking all the defaults.
4. Download GlassFish Enterprise Profile for Load Balancer plugin bits. Start the install by clicking on the downloaded file and select the options as shown below:
   
   
   
5. Copy the following "loadbalancer.xml" in "https-<host>" (replace <host> with the host name of your machine) directory of Sun Web Server installation directory:
   
   

   <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE loadbalancer PUBLIC "-//Sun Microsystems Inc.//DTD Sun Java System Application Server 9.1//EN" "file:///C:/Sun/WebServer7/https-LH-KRKZDW6CJE1V/config/sun-loadbalancer_1_2.dtd "> <loadbalancer>  <cluster name="cluster1" policy="round-robin" policy-module="">   <instance name="instance1" enabled="true" disable-timeout-in-minutes="60" listeners="http://localhost:38080" weight="100"/>   <instance name="instance2" enabled="true" disable-timeout-in-minutes="60" listeners="http://localhost:38081" weight="100"/>   <web-module context-root="/clusterjsp" disable-timeout-in-minutes="30" enabled="true" error-url=""/>   <health-checker interval-in-seconds="7" timeout-in-seconds="5" url="/"/>  </cluster>  <property name="response-timeout-in-seconds" value="120"/>  <property name="reload-poll-interval-in-seconds" value="7"/>  <property name="https-routing" value="false"/>  <property name="require-monitor-data" value="false"/>  <property name="active-healthcheck-enabled" value="false"/>  <property name="number-healthcheck-retries" value="3"/>  <property name="rewrite-location" value="true"/> </loadbalancer>

   
   The parameters to be changed are highlighted in bold and explained below:
   
1. Sun Web Server installation directory
2. HTTP port of instances created in the cluster. The ports specified are the default ones and can be found by clicking on the instance as shown below:
   
   
3. Context root of the application that will be deployed in the cluster. The Domain Administration Server (DAS) can be configured to populate this file whenever any application is deployed to the cluster.
2. Create the cluster as explained in TOTD #67. The admin console shows the following screenshot after the cluster is created and all instances are created/started:
   
    
   
   and the following for 2 instances:
   
   
   
   
3. Deploy "clusterjsp" as explained in TOTD #67. The admin console shows the following screenshot after "clusterjsp" is deployed:
   
   
   
4. Start Sun Web Server using "startserv.bat" in "https-<host>" directory.

• Load balancing for Glassfish V2 deployments using BIG-IP System
• Configure the Cluster/Load Balancer with GlassFish v2

TOTD #57: Jersey Client API - simple and easy to use

TOTD #56 explains how to create a RESTful Web service endpoint using Jersey and publish the resource using JSON representation. The blog entry showed how the endpoint can be accessed from a Web browser. This Tip Of The Day explains how to use Jersey Client APIs to invoke the published endpoint.

Lets get started!

1. Create a new directory "./src/test/java/org/glassfish/samples"
2. Add a test
1. Add a template test file "AppTest.java" as shown below:
   
   

   package org.glassfish.samples; import junit.framework.Test; import junit.framework.TestCase; import junit.framework.TestSuite; /**  * Unit test for simple App.  */ public class AppTest     extends TestCase {     /**      * Create the test case      *      * @param testName name of the test case      */     public AppTest( String testName )     {         super( testName );     }     /**      * @return the suite of tests being tested      */     public static Test suite()     {         return new TestSuite( AppTest.class );     }     /**      * Rigourous Test :-)      */     public void testApp()     {         assertTrue(true);     } }

2. Add a new method "createResource()" as:
   
   

   private WebResource createResource() {         Client client = Client.create();         WebResource resource = client.resource("http://localhost:8080/helloworld-webapp/webresources/myresource");         return resource;     }

   
   This code creates a default instance of Jersey Client and creates a Web resource from that client for the URI passed as an argument.
3. Change the implementation of "testApp()" method as:
   
   

   Greeting result = createResource().get(Greeting.class);         assertTrue(result.greeting.equals("Hi there!"));

   
   This invokes the GET method on the resource by passing specific type and compares the returned and expected value.
   
4. Add the following "imports":
   
   

   import com.sun.jersey.api.client.Client; import com.sun.jersey.api.client.WebResource;

5. Copy "Greeting.java" from TOTD #56 to "./src/test/java/org/glassfish/samples" directory.
3. Run the test
1. Deploy the endpoint as "mvn glassfish:run".
2. Run the test as "mvn test". The following output is shown:
   
   

   ~/samples/jersey/helloworld-webapp >mvn test [INFO] Scanning for projects... [INFO] ------------------------------------------------------------------------ [INFO] Building helloworld-webapp Jersey Webapp [INFO]    task-segment: [test] [INFO] ------------------------------------------------------------------------ [INFO] [resources:resources] [INFO] Using default encoding to copy filtered resources. [INFO] [compiler:compile] [INFO] Nothing to compile - all classes are up to date [INFO] [resources:testResources] [INFO] Using default encoding to copy filtered resources. [INFO] [compiler:testCompile] [INFO] Compiling 1 source file to /Users/arungupta/samples/jersey/helloworld-webapp/target/test-classes [INFO] [surefire:test] [INFO] Surefire report directory: /Users/arungupta/samples/jersey/helloworld-webapp/target/surefire-reports -------------------------------------------------------  T E S T S ------------------------------------------------------- Running org.glassfish.samples.AppTest Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.587 sec Results : Tests run: 1, Failures: 0, Errors: 0, Skipped: 0 [INFO] ------------------------------------------------------------------------ [INFO] BUILD SUCCESSFUL [INFO] ------------------------------------------------------------------------ [INFO] Total time: 4 seconds [INFO] Finished at: Mon Nov 24 16:50:17 PST 2008 [INFO] Final Memory: 18M/43M [INFO] ------------------------------------------------------------------------

4. View request and response messages
1. Change the implementation of "createResource()" method as (changes highlighted in bold):
   
   

   Client client = Client.create();         WebResource resource = client.resource("http://localhost:8080/helloworld-webapp/webresources/myresource");         resource.addFilter(new LoggingFilter());         return resource;

2. Running the tests as "mvn test" now shows the output, with request and response messages, as shown below:
   
   

   Running org.glassfish.samples.AppTest 1 * Out-bound request 1 > GET http://localhost:8080/helloworld-webapp/webresources/myresource 1 > 1 < 200 1 < X-Powered-By: Servlet/2.5 1 < Transfer-Encoding: chunked 1 < Content-Type: application/json 1 < Server: GlassFish/v3 1 < Date: Tue, 25 Nov 2008 07:07:51 GMT 1 < {"greeting":"Hi there!"} 1 * In-bound response Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 1.074 sec

TOTD #18: How to Build The GlassFish v3 Gem for JRuby ?

Jerome posted the instructions to build GlassFish v3 Gem for JRuby - very simple and easy. A binary version of Gem is available here.

1. Software pre-requisite
   1. Subversion client (for example Tigris)
   2. Maven 2.0.x
   3. JRuby 1.0.x (I used JRuby 1.0.2 and lets say installed in JRUBY_HOME).  Make sure JRUBY_HOME/bin is in your path.
2. Build the Gem

   1. As explained in Jerome's entry, you can check out complete GlassFish v3 workspace or just the Gem code. Here is how you'll check out only the Gem code on a Windows machine using Tigris Subversion client:
      
      
      
      And after the check out is complete, you'll see:
      
      

   2. Build the gem by giving the command:
      
      mvn install
      
      And success is achieved by seeing the following in the console:
      
      [INFO] (in C:/workspaces/glassfish/gem/target/dependency/glassfish)
[WARNING] mkdir -p pkg

Travel Tips to Beijing

I arrived in Beijing for Sun Tech Days earlier this week. Here are some travel tips:

1. The Beijing city has Tina'anmen Square and Forbidden City at it's center. Rest of the city is structured in multiple ring roads around the center. Each tourist place can be located as between X and Y ring road easily.
2. If you are a Wells Fargo banker, take the Access Code from Customer Service before boarding the flight. This code allows you to talk to a Wells Fargo banker in USA from anywhere in China. There are separate codes for North and South China. Dial the access code, get the operator, mention the 800-869-TO-WELLS and voila you are connected to the network.
3. Nichole & Renita were gracious to let me share the ride from airport to the hotel so I missed that part of the experience. But it's recommended to walk out of the airport and get a Taxi from the Taxi Stand instead of getting lost in rooks within the airport. It's also recommended to have your hotel name written in Mandarin because the Taxi Drivers may not be able to read/speak English. Once you checked into the hotel you can use your hotel key to show the address (which has the address written in Chinese) to move around the city.
4. Took a guided tour from the hotel to Forbidden City and Great Wall of China. It covered Transportation, Lunch, Parking tickets and Tolls and an English-speaking guide. You can do the same using a private taxi but it may turn out to be slightly costly and most likely you will not get an Mandarin-speaking driver and therefore no guide :) As part of the standard tour, they may take you to a Silk Emporium and Jade Factory, they are fun places just to learn how they are all manufactured.
5. Shopping is a LOT of fun in Beijing. There is a great variety of clothes, toys, gadgets, etc. at local shops. And no shopping is complete without bargaining and that too HARD bargaining. For example when shopping at touristy places, such as street-side shops near Great Wall, bargain HARD. The rule that I followed was to quote the price to 10% of the original. Here are some examples:
    

   Item	Quoted	Paid
   Tee-shirts	1 for 130 RMB	3 for 50 RMB
   Cashmere Scarf (can't be original ;)	1 for 160 RMB	5 for 80 RMB
   Great Wall Memento	350 RMB	20 RMB
   Refrigerator Magnet	20 RMB	5 RMB

   Generally the shopkeepers will give a counter offer but be straight-faced and maintain your price. To keep it easy, just stick to your price and pretend walk away. In all the cases, I was approached with my quoted price :)

6. If you plan to visit Great Wall during November, make sure to carry good warm clothing including gloves and an ear-long cap and a good hiking/walking shoe. It is extremely windy and certain portions of the Wall are really steep.

7. There is no tipping in restaurants and taxi. Don't be surprised if you see a confused look on the person serving if you leave the tip.

And here are the pictures so far:

Sun Tech Days Beijing kick started this morning and a subsequent entry will talk about that.
