This is the 150th tip published on this blog so decided to make it a collection of all the previous ones. Here is a tag cloud (created from wordle.net/create) from title of all the tips:

As expected GlassFish is the most prominent topic. And then there are several entries on NetBeans, JRuby/Rails, several Java EE 6 technologies like JPA, JAX-WS, JAX-RS, EJB, and JSF, and more entries on Eclipse, OSGi and some other tecnhologies too. Here is a complete collection of all the tips published so far:

TOTD #127: Embedding GlassFish in an existing OSGi runtime – Eclipse Equinox

Filed under: eclipse, glassfish, totd — arungupta @ 12:04 pm

GlassFish has a modular architecture based upon OSGi and bundles Apache Felix as the OSGi runtime. TOTD #103 explains how to run GlassFish with two other OSGi runtimes (Equinox and Knopflerfish). However you may already have an OSGi runtime in your environment and like to run GlassFish within it. Sahoo blogged about how to embed GlassFish in Equinox.

This Tip Of The Day (TOTD) provides complete set of steps with Equinox and the different download options.

There are two download options for Equinox – SDK or Framework. The framework is an easier option to start with as its just a single JAR. So create a top-level directory as "equinox-3.5.2" and download the latest framework JAR from here. Complete details about the starting and configuring the framework are described here.

Start the framework and check its status as:

~/tools/equinox-3.5.2 >java -jar org.eclipse.osgi_3.5.2.R35x_v20100126.jar -console

osgi> ss

Framework is launched.

id State Bundle
0 ACTIVE org.eclipse.osgi_3.5.2.R35x_v20100126

Notice only one bundle, i.e. Equinox main bundle, is currently active.

Download and unzip the latest GlassFish 3.1 nightly build.
Shutdown the framework by typing "exit" on the console or Ctrl+C. Copy "glassfish/osgi/equinox/configuration/config.ini" to "equinox-3.5.2/configuration" directory. This is required because the version number of some packages exported by JRE is not uniform across frameworks. This will hopefully be fixed in future versions of the frameworks.
Sahoo’s blog describes an OSGi bundle that controls the lifecycle of GlassFish. Download and unzip the OSGi bundle’s Maven project.
Edit "src/main/java/sahoo/embeddedgf/GFActivator.java" file and change the value of "installRoot" and "instanceRoot" on line 73 and 74 to match the location of your GlassFish install. Build the bundle as:
```
mvn package
```
which generates "target/embeddedgf-1.0-SNAPSHOT.jar". The bundle performs three tasks:
1. Install all the bundles from "glassfish/modules" directory.
2. Creates a configuration with "com.sun.aas.installRoot" and "com.sun.aas.instanceRoot" properties.
3. Starts the main GlassFish bundle.

Start the framework again, install the bundle, and check its status as:

osgi> install file:///Users/arungupta/samples/v3/osgi/embeddedgf/target/embeddedgf-1.0-SNAPSHOT.jar
Bundle id is 1

osgi> ss

Framework is launched.

id      State       Bundle
0       ACTIVE      org.eclipse.osgi_3.5.2.R35x_v20100126
1       INSTALLED   sahoo.embeddedgf_1.0.0.SNAPSHOT

Now GlassFish bundle is installed but not started. Optionally, the framework may be started with "-clean" switch that clears out the cache and starts with a clean slate.

Start the newly installed bundle and see the log messages as:

osgi> start 1

osgi> [#|2010-04-10T10:46:04.616-0700|INFO|glassfishv3.0|com.sun.grizzly.config.GrizzlyServiceListener|_ThreadID=10;_ThreadName=Configuration Updater;|Perform lazy SSL initialization for the listener 'http-listener-2'|#]

Check the status of installed bundle as:

osgi> ss

Framework is launched.

id      State       Bundle
0       ACTIVE      org.eclipse.osgi_3.5.2.R35x_v20100126
                    Fragments=89, 106, 109

2       RESOLVED    org.glassfish.appclient.acc-config_3.1.0.SNAPSHOT
3       RESOLVED    org.glassfish.admin.cli_3.1.0.SNAPSHOT
4       RESOLVED    org.glassfish.admin.core_3.1.0.SNAPSHOT
5       RESOLVED    org.glassfish.admin.util_3.1.0.SNAPSHOT

. . .

223     RESOLVED    org.glassfish.connectors.work-management_3.1.0.SNAPSHOT

osgi>

So now all the GlassFish modules are installed and the required ones are started. "http://localhost:8080" shows the default web page and "asadmin" can be used to issue the standard commands.

If you downloaded Eclipsed SDK, then the framework needs to be started as:

java -jar plugins/org.eclipse.osgi_3.5.2.R35x_v20100126.jar -console

and the configuration file needs to be copied to "plugins/configuration" directory.

A future blog will show how to run GlassFish inside Eclipse as an RCP, however this requires issue #11782 to be fixed.

There are several other OSGi entries on this blog or on Sahoo’s blog.

How are you using GlassFish’s OSGi capabilities ?

Java EE 6, GlassFish, NetBeans, Eclipse, OSGi at Über Conf: Jun 14-17, Denver

Filed under: eclipse, glassfish, javaee, netbeans — arungupta @ 10:54 am

Über Conf is a conference by No Fluff Just Stuff gang and plans to blow the minds of attendees with over 100 in-depth sessions (90 minutes each) from over 40 world class speakers on the Java platform and pragmatic Agile practices targeted at developers, architects, and technical managers.

Get your hands dirty and learn from the industry leaders in an intimate setting where the attendance is capped at 500 and in the beautiful city of Denver.

I’ll be speaking on:

Java EE 6 & GlassFish v3: Paving the path for the future
Getting the best of both worlds: OSGi & Java together

The talks will start with an introduction of key concepts and then provide a detailed overview of the technology. The talks will be interspersed with multiple demos to leave you feel empowered. There will be NetBeans and Eclipse (hopefully IDEA too) showing the simplicity, ease-of-use, and increased productivity with Java EE 6. There will be multiple demos showing OSGi application development and how OSGi + Java EE leverage the best of both worlds.

Keeping with the spirit of "No Fluff Just Stuff", the material presented will be purely technical

Hear Jay Zimmerman (Über Conf Director) talk about the event. My first engagement with NFJS was Rich Web Experience 2007 and that was a great experience, truly "rich". This is my first speaking engagement with NFJS and looking forward to a long term relationship

On a personal front, I never ran in Denver so looking forward to some nice runs in the mile high city! Any recommendations ?

Day 2 – Tech Days 2010, Hyderabad

Filed under: eclipse, glassfish, javaee, netbeans — arungupta @ 11:30 pm

Follow up from Day 1.

The opening of Day 2 started with "awesome", "fantastic", and "extraordinary" as the feedback when Simon asked about the Day 1. The attendees charged into the Hyderabad International Convention Center, the venue of Tech Days, on Day 2 as evident in the video below:

Georges Saab, Vice President, Fusion Middleware, Oracle talked about Oracle Application Grid and its various components such as WebLogic, Tuxedo, JRockit, Coherence, JDeveloper, ADF, and EclipseLink. Nandini Ramani showcased how Java platform has evolved over past few years and modularity is one of the key themes going forward. Her talk was loaded with several demos including mine on JSF, CDI, Bean Validation, and JAX-RS using NetBeans.

The "strange and unusual talent show", a usual activity on Day 2, had 9 participants and its probably the largest group I’ve ever seen. The attendees are encouraged to show their talent and it ranged from a poem, martial arts, dancing, singing, and many others. Watch all the fun in the video below:

My session on "Using the latest Java Persistence API 2 Features" was well received in a packed hall (with a capacity of 1500) and the slides are now available:

Using the latest Java Persistence API 2 Features – Tech Days 2010 India

Always good to see instant feedback via #techdays:

@javachap: In @arungupta session, Java Persistence API. It’s houseful! #techdays
@mohdabdurraafay: @arungupta your session was awesome. was very much in depth. Thanks. #techdays #techdays2010

DevNexus 2010 Trip Report

Filed under: eclipse, glassfish, javaee, netbeans — arungupta @ 9:20 pm

As mentioned earlier, I presented on Java E 6 & GlassFish v3 at DevNexus earlier this week. This is an annual conference by Atlanta Java Users Group and had three parallel tracks.

The conference was a sold out and the attendees packed Cobb Galleria conference rooms on both the days.

Anyway, the slides from my session are available below:

Java EE 6 & GlassFish v3 @ DevNexus

The speaking slots were bigger than normal, 70 minutes as opposed to normally 45 or 50 minutes. So that allowed to spend more time on the demos and show all the simplicity and ease-of-use with Java EE 6. Optional "web.xml" is particularly well appreciated And the attendees were hopeful that other vendors will start supporting Java EE 6 soon. For the record – Caucho, Geronimo, JBoss, and WebLogic have announced plans to be Java EE 6 compliant.

If you are interested in learning about Java EE (and several other topics), then GCA.net offers several of them all over the country. You can even avail a 10% on any class by registering at gca.net/devnexus. And if you are interested in specific learning paths on Java EE 6, then Oracle University has well designed courses.

Personally, I got to meet Dan Allen, Burr Sutter, James Ward, Venkat Subramaniam and many others. Burr is always an energetic personality and was live tweeting photographs of all the speakers. I loved his opening statement that DevNexus is about people who do what needs to be done, not who thinks what needs to be done. Basically he was joking on differences between "architects" and "developers" I also had some brief discussions with Dan on how Java EE adoption is important for the enterprise. His presentation on Contexts & Dependency Injection explained the concepts in simple manner. HIs slides should be soon available on Seam Wiki. Venkat’s keynote on Tuesday morning on "Facts and Fallacies of Software Development" was quite animated and simply superb. Here are some quotes from his talk:

A professional who doesn’t learn to fail, fails to learn
If a language is more typed, you type less (e.g. Scala). If a language is less typed, you type more (e.g. Java)
Standardization before innovation is a bad idea, that’s why EJB 1.0 suck so bad
It’s the lack of clear business objective, not lack of money & time that leads to failure
Passion, Competency, Responsibility – 3 things that can make your company succeed

I’m certainly looking forward to his keynote at Spark IT 2010 next week.

Finally some pictures from the conference:

And the complete album is available at:

Here is a brief number summary of the 2-week conference circuit starting next week:

3 conferences
8 sessions + 1 hands-on workshop
2 cities
6 days
3 Hotels
3 Airlines
Infinite meet/greet sessions

And then of course there is another one on Java EE 6 & GlassFish in Dallas on April 5, thank you GCA

Developer Tools Strategy by Oracle+Sun: NetBeans & Hudson to stay!

Filed under: eclipse, netbeans — arungupta @ 6:26 am

Hear Ted Farrell, Chief Architect and Senior Vice President talk about Oracle and Sun Java Developer Tools Strategy.

Here is a summary for those who want a quick juice:

Productivity With Choice
- Choose the right tool set for your needs
- Shared infrastructure across tools with Hudson, Oracle TPC, Subversion. Bugzilla, Maven, etc.
- NetBeans continues with strong Java focus
- Combine and integrate the best features across tools
More resources for Developers
- Netbeans.org, java.net, otn.oracle.com
- More courses/training on Java technologies
- More conferences around the world
- Better products from expanded R&D and partner ecosystem
- Larger combined developer community

Here is a lovely snapshot from the webcast …

Some more detailed points captured from the webcast …

If you are a NetBeans user today, you’ll continue to be a NetBeans user after acquisition.
Increase the investment in Hudson, lots of synergy with Team Productivity Center.
Discontinue the public interface for kenai.com for now, fits very well with some internal projects. Read more about the future of kenai.com.
Want to make the best Java IDE for the Java platform. NetBeans platform is very important to lot of customers.
For NetBeans, turn to community for external non-Java like Dynamic Languages. Invest more in the infrastructure and community.
netbeans.org unchanged
Community participation is key for:
- NetBeans plug-ins
- Building apps on NetBeans Platform
- Emerging, Dynamic Languages
- Dialog, interaction, lists, docs, events, JUGS, etc
No licensing changes
- Versions of NetBeans <= 6.7 follow Sun policy
- Versions of NetBeans >= 6.8 follow the Oracle policy (complete details)

The webcast also talks about JavaOne being co-located with Oracle Open World (Se 19-23, 2010) and also expanding to Brazil, Russia, India, and China.

oracle.com/tools for more details. The complete list of webcasts + slides from yesterday’s event are now available.

There are several other articles (in no particular order):

Oracle reveals strategy forGlassFish, MySQL, OpenOffice, and Solaris

TOTD #115: GlassFish in Eclipse – Integrated Bundle, Install Stand-alone or Update Existing plugin

Filed under: eclipse, glassfish, javaee — arungupta @ 10:00 am

There are three options for Eclipse users interested in exploring GlassFish. They can either use an integrated bundle, install the GlassFish plug-in in an existing Eclipse version, or update their older GlassFish plugin to the latest version. These options are explained below.

GlassFish Tools Bundle for Eclipse 1.1 is an integrated bundle based on Eclipse 3.4.2 and includes GlassFish v2 and v3 pre-registered and configured and optionally JDK 1.6 U12. The work towards version 1.2 can be tracked by following the 1.1.x releases (1.1.7 is the latest). This new version is based on Eclipse 3.5.1, includes GlassFish v3 build 74 pre-registered and configured, several plugins (JSF Facelets, JAX-WS, Maven m2) and several Java EE 6 wizards to provide a seamless development and deployment experience with Java EE 6 & GlassFish v3. There are several other niceties in the newer release like pre-registered MySQL JDBC driver, Java EE 5 and Java EE 6 javadoc and code completion.

However what to do if you are already using an Eclipse version in your environment ?

The basic requirement is Eclipse 3.4+. A GlassFish plugin can be easily installed in any Eclipse 3.4+ and provides all the GlassFish-related functionality. The screencast #28 shows how to get started with Eclipse 3.4.2 and configure GlassFish as a standard server adapter.

If you are using Eclipse 3.5.0, then the standard technique described in the above screencast will not work because of the issue #280365. Fortunately, the bug report also has a workaround. Instead of using the "Download additional server adapter", install using the "Help", "Install New Software …" and explicitly adding the GlassFish plugins update site. A screen snapshot looks like:

If you are using Eclipse 3.5.1, then the standard technique of "Download additional server adapter" works as described in the screencast #28. A screen snapshot looks like:

If you already have an existing version of GlassFish plugin installed, then it can be updated as described in TOTD #66. The process is much more simplified now and menu items have changed little bit in Eclipse 3.5.x – "Check for Updates" instead of "Software Updates …". The screen snapshot looks like:

Now you can start developing your applications using Eclipse. Several blog entries have already been published:

TOTD #102 explains how to use Servlet 3.0 and EJB 3.1 wizards in Eclipse.
TOTD #99 explains how to create a JPA 2.0 compliant application.
TOTD #98 explains how to create a Metro JAX-WS Web service.
TOTD #54 shows how to create a JavaServer Faces application with Eclipse.

Future blogs will provide more details on the new features added recently. Until then, the GlassFish Plugin Release Notes provide a summary.

On a slightly different note, you can even run GlassFish with Eclipse Equinox OSGi runtime as explained in TOTD #103.

Oracle Open World 2009 – Day 2 Report

Filed under: eclipse, glassfish, javaee, netbeans — Tags: openworld, oracle — arungupta @ 11:01 pm

Following from Day 1, the Day 2 started with Charles Phillips and Safra Catz keynote. The keynotes at Open World are significantly different from JavaOne or any other developer conference I’ve attended so far. Of course they are expected to be because Open World is not primarily a developer’s conference. Oracle Develop (OD) certainly closely mimic any of the conferences I’ve typically attended. My "exhibitor" badge restricted me from attending any of the sessions at OD though

Here are some interesting statistics about the conference:

5 content streams (Database, Applications, Industries, Management & Infrastructure, & Middleware)
314 demo kisosk
401 partners & customer exchibiting
1966 educational sessions (10% more than last year)
4500 Oracle developers/experts for you
81,266 hotel room nights
170,000 cups of coffee
182,000 online participation

Here are some interesting sightings from the Open World exhibitor pavilion:

Tata Consultancy Services, Infosys, HCL, Wipro, Mahindra Satyam, Birlasoft, Cognizant and a host of other companies based in India are exhibiting in the pavilion. This is a pleasant surprise from JavaOne which typically does not see these many companies out of India.
Poker, Ducati, Glider, Beatles Guitar, Sumo wrestler, Callaway Golf, Mini Cooper and other similar sightings were spotted. Check out complete set of images here.
Lot more attendees are wearing a suit, quite unlike JavaOne or RailsConf which is typically denim/t-shirt rich.

On a personal front, everything that possibly could went wrong as part of the demo installation yesterday and rehearsal for my talks earlier today. NetBeans was not able to connect to the Oracle database (couple of machine restarts solved that), GlassFish Tools Bundle for Eclipse was timing out attempting to start GlassFish (removing workspace solved that problem), NetBeans’s RESTful tooling not recognizing JPA entities, and also found a blocking bug (issue #10166) in deploying Rails app to latest GlassFish promoted build. These demos have worked seamlessly for me all the time time and fortunately worked well during the talk.

My talk at the Unconference on Creating Quick and Powerful Web applications with Oracle, GlassFish and NetBeans/Eclipse went well. It was truly an unconference event with no projector or mic in the presentation room. But the small attendance allowed us to huddle around the table and luckily all the demos worked seamlessly. The slides are available at:

Several demos shown in the talk are available at:

Java EE 6 wizards using NetBeans and Eclipse
Deploy on Save using NetBeans and Eclipse
Connecting Oracle database to NetBeans
Creating JPA entities from a sample Oracle database
Exposing Oracle database table as RESTful entities
Rails application using Oracle and GlassFish

The slides have pointers to several other demos as well. Also showed the simplicity of Java EE 6 development using Eclipse in Java Platform, Enterprise Edition: The Foundation and Future of Your Enterpise.

The day concluded with OTN Night in Howard St tent. Check out a brief video from the event:
