GlassFish and NetBeans at MySQL Users Conference 2009
What is open source, production-quality, supported by a large vibrant
community, and comes with full enterprise support ? - GlassFish and MySQL.
Did you know that GlassFish ...
- is the only open-source Java EE 5 compliant Application Server
- can be used to deploy Rails, Grails, and Django applications
- has 13x better price/performance than Dell/HP, and therefore a much lower TCO
- has an easy-to-use and intuitive web-based administration console
- has enterprise features like clustering/high availability, .NET-interoperable Web services, ...
There are several other advantages which I'll be speaking on Creating Quick and Powerful Web Applications with MySQL, GlassFish, and NetBeans and the coordinates are:
| When: | April 21, 2009 (Tuesday), 3:05 pm |

TOTD #78: GlassFish, EclipseLink, and MySQL efficient pagination using LIMIT
EclipseLink
JPA replaces TopLink
Essentials as the JPA implementation in GlassFish v3. One
of the benefits of using EclipseLink is that it provides efficient
pagination support for the MySQL database by generating
native SQL statements such as "SELECT ... FROM <table>
LIMIT <offset>, <rowcount>".
The MySQL LIMIT clause definition
says:
The
LIMIT clause can be used to constrain the number of rows returned by
the SELECT statement. LIMIT takes one or two numeric arguments, which
must both be non-negative integer constants (except when using prepared
statements).
With two arguments, the
first argument specifies
the offset of the first row to return, and the second specifies the
maximum number of rows to return. The offset of the initial row is 0
(not 1):
SELECT * FROM tbl LIMIT
5,10; # Retrieve rows 6-15
So instead of fetching all rows from the database and then filtering
from row 6-15, only rows 6 through 15 are fetched.
This TOTD (Tip
Of The Day) explains how to
create a JPA Persistence Unit for sakila
(MySQL sample database) using NetBeans,
use EclipseLink as the Persistence Provider, and then write a JPA query
to leverage the pagination support - all on GlassFish v3.
- Create a Persistence Unit for "sakila" as explained in this blog using bullets #1 - 3. The differences are explained below:
- In 2.1, choose "GlassFish v3 Prelude" as the server. Even though "GlassFish v3 Prelude" is chosen as the server but it will be replaced with a recent promoted build because pagination feature is not implemented in the Prelude. Alternatively you can use NetBeans 6.7 M3 and GlassFish v3 as explained here.
- In 3.3, EclipseLink
is shown as the default Persistence Provider as shown below:
- In 3.5, there is no need to specify the properties for
"user" and "password as the JDBC resource is stored in the server
configuration. Instead specify the following property:
<properties>
<property name="eclipselink.logging.level" value="FINE"/>
</properties>
This will log any SQL statement sent by JPA to the underlying persistence provider (EclipseLink in this case). - If GlassFish v3 was configured using NetBeans 6.7 M3, then
the JDBC Connection Pool and JDBC resource were created in the server
directly. If not, then download and unzip the latest GlassFish v3 latest
promoted build (b43
as of this writing). Create the JDBC Connection Pool as:
./asadmin create-jdbc-connection-pool --datasourceclassname com.mysql.jdbc.jdbc2.optional.MysqlConnectionPoolDataSource --property user=duke:password=glassfish:ServerName=localhost:portNumber=3306:databaseName=sakila jdbc-mysql-pool
and the JDBC resource:
./asadmin create-jdbc-resource --connectionpoolid jdbc-mysql-pool jndi/sakila
GlassFish v3 b43 bundles "Eclipse Persistence Services - 2.0.0.r3652-M1". A later blog will explain how to replace the bundled EclipseLink version with a newer/different EclipseLink version. - Create a new Servlet "QueryServlet". Inject the
javax.persistence.EntityManagerFactory resource:
@PersistenceUnit
EntityManagerFactory emf;
and change the "processRequest" operation to:
EntityManager em = emf.createEntityManager();
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
try {
int startRow = Integer.valueOf(request.getParameter("start_row"));
int howMany = Integer.valueOf(request.getParameter("how_many"));
Query q = em.createNamedQuery("Film.findAll");
q.setFirstResult(startRow);
q.setMaxResults(startRow + howMany);
for (Object film : q.getResultList()) {
out.print(((Film)film).toString() + "<br/>");
}
} finally {
out.close();
}
This Servlet reads two parameters from the request and sets parameters on the JPA Query to enable pagination. - Deploy the application on GlassFish v3.
- Using NetBeans 6.7 M3, select "Deploy" from the context-sensitive menu.
- Using NetBeans 6.5.1, select "Clean and Build" and then manually deploy the WAR file using "asadmin deploy dist/Pagination.war".
The log file in "domains/domain1/logs/server.log" show the following SQL query generated by EclipseLink:
| [#|2009-04-07T14:01:12.815-0700|FINE|glassfish|org.eclipse.persistence.session.file:
/Users/arungupta/tools/glassfish/v3/b43/glassfishv3/glassfish/domains/domain1/applications/Pagination/WEB-INF/classes/-PaginationPU.sql|
_ThreadID=15;_ThreadName=Thread-1;ClassName=null;MethodName=null;|SELECT
film_id AS film_id1, special_features AS special_features2, last_update
AS last_update3, rental_duration AS rental_duration4, release_year AS
release_year5, title AS title6, description AS description7,
replacement_cost AS replacement_cost8, length AS length9, rating AS
rating10, rental_rate AS rental_rate11, language_id AS language_id12,
original_language_id AS original_language_id13 FROM film LIMIT ?, ? bind => [1, 11]|#] |
As you can see, the query uses the LIMIT clause which optimizes the data returned from the table.
If a different database, for example Derby, is used then the generated SQL query looks like as:
| [#|2009-04-07T17:00:34.210-0700|FINE|glassfish|org.eclipse.persistence.session.file: /Users/arungupta/tools/glassfish/v3/b43/glassfishv3/glassfish/domains/domain1/applications/Pagination/WEB-INF/classes/-PaginationPU.sql| _ThreadID=15;_ThreadName=Thread-1;ClassName=null;MethodName=null;|SELECT film_id, special_features, last_update, rental_duration, release_year, title, description, replacement_cost, length, rating, rental_rate, language_id, original_language_id FROM film|#] |
In this case, the entire table is fetched and the rows are filtered based upon the critieria specified on the client side.
If the number of rows is huge (a typical case for enterprise) then MySQL provides efficient fetching of records. And GlassFish v3, with EclipseLink JPA integrated, makes it much seamless for you.
Thanks to Mr GlassFish Persistence (aka Mitesh :) for helping me understand the inner workings.
Discuss this more at Creating Quick and Powerful Web Applications with MySQL, GlassFish, and NetBeans technical session in the upcoming MySQL Users Conference!

Here are some quotes from a recent
article talking about Oracle's
maintenance and support fees:
Before Oracle acquired
BEA earlier this year, the company charged 18% to 20% for support and
maintenance. Oracle increased those fees to meet its own structure and
also raised list prices on most BEA products.
That didn't sit well.
and
One Java-centric VAR,
who spoke on the condition of anonymity, said some of his BEA WebLogic
customers are moving to alternative application servers just to get
away from Oracle.
and
"What company comes in
this climate and not only jacks up prices but support prices as well?"
asked one frustrated BEA customer, who spoke on the condition of
anonymity.
and
"Many SAP and Oracle
customers intend to push back their maintenance fees," he said.
"Customers seek an option to just pay for tax and compliance updates
without paying for future innovation. They are willing to pay for
future modules when that time comes. If they can't access such options,
they would prefer third party options like Rimini Street for Oracle
[E-Business Suite] and SAP's applications."
Have you been bitten by Oracle's price raise ?
Interested in an industry-grade, highly performant, feature-rich, and
open source alternative ?
GlassFish and MySQL together provide an excellent
choice - give it a try!

Sun Tech Days 2009, Singapore - Welcome Reception
Follow up from Part
1.
Attended "What Developers should care about MySQL ?" by Colin and
"Groovy and Grails" by Chuk-munn
Lee.
I enjoyed both the talks for different reasons. Colin's talk explained
the pluggable
storage engine architecture that is unique to MySQL
(pronounced my-ess-kew-ell,
not my-sequel).
It was interesting to know that the different storage engines can be
picked a la carte
based upon the requirements. The performance comparison for INSERTs was
5x between MyISAM, InnoDB and Archive storage engines. But then InnoDB
provide transactions and other goodies. Multiple performance tuning
tips such as using negative unsigned int instead of BIGINT and
partitioning databases if the number of records grow more than 1 billion were good! Keep an eye
on his blog
for slides.
Chuk's talk introduced Groovy, Grails,
showed several samples of NetBeans
and Grails
integration. A Grails application can be deployed as a WAR file on
GlassFish. Alternatively you can download the Grails module from GlassFish v3 Update
Center and use the standard "run-app" command to run your
Grails application using the embedded GlassFish v3 instead of Jetty.
This
is explained nicely in the screencast below:

Sun Tech Days 2009, Singapore - Day 1
The Sun Tech Days
Singapore started earlier this morning - over 1100
developers, an outstanding audience!!!
The kick off had a good local flare when the Gods of
Longevity, Fortune, and Prosperity (Fu Lu Shou) showed up to
start the event ;-) The build up to their appearance was really
exciting as evident from
the video below:
This particular event will also be recorded in Singapore
Book of Records for the largest numbers of Sun developers
playing
a rattle together :) Here are some pictures from the event:

A Toshiba laptop and an iPod was raffled to the audience and the lucky winners are:
 |
 |
And found another loyal reader of my blog:
Gosh, he even took my autograph ;-)
The steps to reproduce the different GlassFish demos shown during the key note are explained below.
- GlassFish v3 OSGi-compliance and quick startup time
Download GlassFish v3 Prelude from here, unzip, and start the server as
glassfish/bin/asadmin start-domain --verbose
to see a message something like:
INFO: GlassFish v3 Prelude startup time : Felix(1732ms) startup services(1091ms) total(2823ms)
The GlassFish v3 container starts up fairly quickly, 2.8 secs in this case, without starting any application-specific container. The container is using OSGi R4 APIs and Apache Felix as the runtime. This allows any standard OSGi bundle to be easily deployed in GlassFish v3. The underlying OSGi runtime can be easily replaced with Knopflerfish or Equinox because standard R4 APIs are used. As you notice, Felix start up time is explicitly shown in the startup message.
The quick start up is possible because containers, such as Web container that serves web applications, is started only when the first Web application is deployed. No web application, no web container - simple! The same is true as other types of applications are deployed, for example a Rails application. The containers are started and stopped on demand giving a higher utilization of resources. - Auto-deploy of Servlets and preserving servlet session state across multiple re-deploys using NetBeans and Eclipse. This feature is really useful as it tremendously reduces your development time. Focus on what you are good at i.e. adding business logic and let NetBeans and GlassFish together take care of your deployment worries. And why should you loose your session state just because the application is re-deployed!
- Modularity
and Extensibility of GlassFish v3 by running/debugging a Rails
application. GlassFish certainly supports traditional Java EE
applications. But starting with GlassFish v3 the newer Web frameworks
like Rails can also be deployed natively. The screencast
#26
shows how to develop, run and debug a Rails application natively
deployed on GlassFish. And this capability of deploying a Rails
application is added as an OSGi module and also demonstrates the
extensibility of GlassFish.
It provides future protection as well because any other Web framework can be easily deployed as a standard OSGi module. - Extensibility
of GlassFish v3 by dropping a JAR in the "/modules" directory. The
admin console is a one-stop interface for the administration of your
GlassFish instance such as deploying WAR/EAR, creating JDBC/JMS
resource, and creating clusters. Starting with GlassFish v3, even the
admin console is extensible. There are clearly defined extension points
that allows you to write a "admin console module" and extend the
capability of your admin console. The demo showed dropping a JAR in the
standard "modules" directory and admin cosole recognizing the module. A
sample project that shows all the integration points to GlassFish v3
Admin Console is available here.
Also met Colin Charles, Community Relations Manager for MySQL at Sun Microsystems. It was certainly great to know that similar thought process is applied for promoting both GlassFish and MySQL - state the facts, offer an alternative, and let the customers decide. Both MySQL and GlassFish are open source offerings with complete enterprise support available from Sun Microsystems. And together with OpenSolaris, NetBeans and many other open source offerings they make a killer platform for developing/deploying any kind of web applications.
And if you have not signed up for Cloud Camp event happening in Singapore tomorrow at 6pm, register here!

TOTD #65: Windows 7 Beta 1 Build 7000 on Virtual Box: NetBeans + Rails + GlassFish + MySQL
Microsoft released Windows 7
Beta 1 - the next major version of Vista, download
here. There are tons
of improvments mostly centered around making the content
easily & intuitively accessible. But hey, Mac OSX already
serves
that purpose well for quite some time ;-)
But I still want to make sure that our Rails stack (NetBeans,
GlassFish,
and MySQL) work fine on it. And it very well do, without any issues, as
you'll realize at the end of this blog :)
Lets first get started with installing Windows 7 Beta as a Virtual Box
image. Few points to note here:
- Only IE can be used for downloading Windows 7 Beta, FireFox & Safari on Mac do nothing (confirmed). With a growing share of both Mac and Firefox (TODO: add a link), I think this combination needs to be at least included on their testing matrix. There was no clear way to file bugs but sent feedback using "Send Feedback" button that is omnipresent on top-right corner of each window.
- The 64-bit Windows 7 installer do not work on Virtual Box 2.1 installed on a 64-bit MacBook Pro. So had to download the 32-bit installer instead :( This seems to be a Virtual Box bug so filed #3027.
- The 32-bit and 64-bit files are named "7000.0.081212-1400_client_en-us_Ultimate-GB1CULFRE_EN_DVD-32bit.iso" and "7000.0.081212-1400_client_en-us_Ultimate-GB1CULXFRE_EN_DVD.iso" respectively. If you noticed the only difference is the letter "X" before "FRE" . This required a deep look to spot the difference and very non-intuitive. Frankly, I had to put the two names above each other to spot the difference ;-)
Anyway, after that the install process was pretty simple. Anybody who has previous Windows install experience can vouch the installation mostly goes seamless, as was the case here. The complete installation using screen snapshots is shown here. Some of the snapshots from my install process are shown below:
Ta da ... after multiple boots during installation, the final welcome screen shows up as following:
Even the beta install required an activation key. The key is shown on the screen after the download. A freshly installed Windows 7 Beta shows the following disk properties:
Lets install our Rails stack.
Download JDK 6 U11 (TODO: check with or w/o NetBeans), MySQL 5.1, NetBeans 6.5 (which includes GlassFish v3 Prelude, JRuby 1.1.4, Rails 2.1, and other goodies)! Alternatively, you can also download JDK 6 U11 + NetBeans 6.5 co-bundle here.
Install them in the same order by double-clicking on the downloaded bundle and taking all default values.
First MySQL installation ...
MySQL is automatically started and registered with Windows as a service.
And then NetBeans installation ...
Because of the default access controls setup in Windows 7 (as in Vista as well), NetBeans need to be run as an administrator by right-clicking, selecting "Run as administrator". Screencast #26 shows to develop, run, and debug a Rails application on GlassFish v3 Prelude. Here are some screen snapshots as the steps outlined in that screencast are performed.
Here is a snapshot that shows how a simple Rails application can be created:
Running the Rails application on GlassFish v3 Prelude ...
And now debugging using the NetBeans IDE ...
Overall, I'm happy with the first experience of Windows 7 Beta 1. The install process was smooth and it was nice to see the picture of a fish on the welcome screen. They can even consider swapping it with a glassfish ;-)
TOTD #64 showed how to install OpenSolaris 2008/11 using Virtual Box and run the same stack there. So be it Windows 7 or Open Solaris 2008/11, you can develop, run, and debug your Rails application with pleasure using NetBeans and GlassFish. And of course, Mac OS X :)
What is your primary Operating System for development ?
Do you use any Virtualization software for trying multiple Operating Systems ? Which one ?

GlassFish @ University of Essex and Frankfurt - Go Campus Ambassadors!
This blog highlights couple of contributions by Campus
Ambassadors (CA) from
University of Essex
and Frankfurt
towards GlassFish.
 |
Jenya Kovalchuk (Campus Ambassador in the University of
Essex, UK) gave a talk
on GlassFish. The pre- and post-conditions of talk are really
compelling: |
Pre-condition: No one out of 25 present ever heard about GlassFish
Post-condition: Everyone is looking forward to put their hands on, how great it is! dear all, we are approaching labs where the software is already installed…
That means there are approx 15 more students who are now trying their hands on GlassFish :)
 |
Igor Geier from University of Frankfurt developed a A MySQL GlassFish application. The application is a work-in-progress but it sure will show the ease-of-use of GlassFish and tight integration with NetBeans. |
Thank you very much for talking about/using GlassFish!
Please drop a comment on this blog if you have talked about GlassFish in your school/university/training. If you'd like to talk about it then spotlight.dev.java.net/start provides a comprehensive list of material (slides, demos, etc.) to get you started!
Check out how widespread CAs are in this global map. Follow their aggregated blogs for details on what they are doing.

TOTD #64: OpenSolaris 2008/11 using Virtual Box
Here is a blog entry that was sitting in my Drafts folder for a long
time
(just because I didn't realize :). Anyway, it shows how to install Open Solaris 2008/11
on Virtual Box.
The original install was done using Virtual Box 2.0.6. I installed
Virtual Box 2.1 this morning and the image was easily recognized by the
updated Virtual Box.
Here are the basic steps.
Create a new VM ...
As part of the previous step, create a new Virtual Disk mapping to the
downloaded Open Solaris image ...
The generated VM settings are shown as below:
Click on "Start" and configure for the first run as:
Boot the Virtual Macine from the LiveCD shows the following GRUB:
Take the default for Language and Keyboard and then the following
screen is shown after the boot:
Click on "Install OpenSolaris" ...
Clicking on "Install" starts the installation ...
And finally the install is completed.
Click on "Reboot", select "Boot from Hard Disk" and press Enter ...
And then select if "full boot" or "text boot" is required as shown:
And the welcome screen is shown as:
Now you can develop your Rails
applications using the NetBeans
IDE and deploy them on GlassFish
and MySQL easily as
explained here.
There are multiple updates to the stack described earlier - JRuby 1.1.6,
Rails
2.2, MySQL
Alpha 6.0.x, GlassFish
v3 Prelude, and Virtual Box
2.1.
So go ahead and develop, deploy, and debug your Rails applications as
described in screencast
#26. You can even manage your Rails applications using JMX as
described in TOTD #61,
#62,
and #63.
Hwo do you follow the latest on each technology:
- Open Solaris at The Observatory and twitter.com/opensolaris.
- Virtual Box at Virtual Box Buzz.

TOTD #60: Configure MySQL 6.0.x-alpha to NetBeans 6.5
This Tip Of The Day answers the
following comment
on my blog:
How to Configure a MySql database to be able to connect Netbeans6.5.?
I've tried using mysql Server 6 many times, but it fails.
Please, let me know how to fix that problem.
- Download MySQL 6.0 from here.
- Install and start MySQL 6.0 on Mac OSX using the clearly written installation instructions.
- Basically the download is available in .tar or .dmg format. Using .dmg format is the easiest way, double-click and follow the instructions taking all defaults.
- MySQL is installed in
"/usr/local/mysql-6.0.8-alpha-osx10.5-x86_64" and the soft link is
adjusted so that its available from "/usr/local/mysql". The directory
structure looks like:
lrwxr-xr-x 1 root wheel 32 Jan 5 14:00 mysql -> mysql-6.0.8-alpha-osx10.5-x86_64
drwxr-xr-x 3 root wheel 102 Jan 5 14:00 mysql-5.0.45-osx10.4-i686
drwxr-xr-x 17 root wheel 578 Nov 3 21:02 mysql-6.0.8-alpha-osx10.5-x86_64 - Start MySQL server as: "sudo mysqld_safe" to see the
output as:
~ >sudo mysqld_safe
090105 14:20:51 mysqld_safe Logging to '/usr/local/mysql/data/dhcp-usca14-133-38.SFBay.Sun.COM.err'.
090105 14:20:52 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data - In NetBeans 6.5, Services tab, right-click on "Databases"
and click on "Register MySQL Server..." as shown below:
- Take the default values, if your MySQL
instance is running on the default ports, as shown below:
and click on "OK". If your database is already running then NetBeans will automatically connect with the database. If the database is not running then start it as explained above, right-click on the newly added database as shown below:
and the default databases are then shown as:
More details about configuring MySQL in NetBeans 6.5 are explained in the official documentation.

There were lots of great entries and picking one was a tough decision.
But luckily the process was simple and clearly defined for all the
judges. Each submission was assigned numbers between 1-100 in
8 pre-defined criteria and then a winner was picked. Now, don't ask us
about the total marks for each entry or the winning margin ;)
Thanks to all the judges for reviewing the entries!
Here are some guidelines I followed during the review:
- I looked at the blog and project website, how do I get started ?
- Is the project site well structured, with links to code, docs, etc ?
- Is there an installation/user manual ?
- Is the application a stereotype
- Is testing (unit, integration, stress, reliability, performance and others) integral part of the project ?
- Is it a simple JSP/Servlet application or any creative use of GlassFish ? For example, is the participant using Web services, Grizzly Comet, Rails, Grails, Admin console, Monitoring or any such features.
- Any usability or functionality bugs filed during project development ?
- How useful is the application in context ?
- Any NetBeans- or Eclipse-GlassFish integration features used ?

CIO published an article
highlighting 5 cheap (or free) software that can be afforded during
financial crisis. Their recommendations are:
- Open Office ($0) instead of Microsoft Office ($110 for basic version)
- Mozilla Thunderbird ($0) instead of Microsoft Outlook (lots of security issues)
- GnuCash ($0) instead of Quicken ($30 for starter edition)
- Alfresco ($0) instead of Sharepoint ($5K for five licenses)
- Linux instead of Windows (non-zero cost, always virus-prone ;)
Here are some more recommendations ...
- GlassFish instead of Oracle Weblogic or IBM Websphere
- MySQL instead of Oracle Enterprise or IBM DB2
- OpenSolaris instead of Windows
- NetBeans instead of IntelliJ
- VirtualBox instead of VM Ware or any other virtualization software
- and many more here
Now some actual price comparisons using GlassFish and MySQL Unlimited ...
That's $3 million savings over a period of 3 years!!!
And if the number of sockets/cores go up, that's just additional money you are wasting during this financial crisis. With GlassFish Enterprise Unlimited starting at $25,000 - no counting cores, sockets, support incidents, servers or auditing - you can deploy unlimited GlassFish instances for the same price charged for one WebLogic Enterprise Edition. GlassFish for Business explains the value of buying subscription for your deployments.
Here is another comparison for Total Cost of Ownership for MySQL compared with other databases:
Can your apps scale more than Google, Facebook, Yahoo or Wikipedia ? All these sites are powered by MySQL. Do they need to be more reliable than telco vendors such as Vodafone ? Again powered by MySQL.
In an open source world, why have a "30-day" evaluation period ?
In the times of financial crisis, why spend extra money when there are other better options available with HUGE savings ?
Open Source software is indeed a great way to cut costs. And Sun Microsystems offer a wide varitey of open source offerings (GlassFish, MySQL, OpenSolaris, VirutalBox, Linux, NetBeans and many others) that can help you during this financial crisis!
