TOTD #66: GlassFish Eclipse Plugin 1.0.16 - Install v3 Prelude from the IDE

GlassFish Plugins team released ver 1.0.16 of Eclipse plugin for GlassFish. The team has maintained pretty good cadence in terms of adding features and fixing bugs in the plugin (16 releases in approx as many months). However this particular version has an exciting feature. It allows GlassFish v3 Prelude to be installed from within the IDE itself.

If you have not installed GlassFish plugin in your Eclipse earlier then screencast #28 shows how to get started. However the screencast requires you to pre-install GlassFish outside the IDE. Instead, as explained in this blog, you can skip to here and install the Application Server from within the IDE.

If you have a previous installation of GlassFish plugin, then it needs to be updated using the steps described below. And finally install the Application Server from wtihin the IDE.

Lets get started!

In Eclipse, go to "Help" menu item, "Software Updates ..." and it shows the complete list of plugins installed along with their versions ...



GlassFish plugin version is 1.0.14 in this case. Click on "Available Software" tab to show all the available updates as shown below:



The GlassFish plugin update site is automatically added to the list of managed sites once you install the plugin, but it is not automatically checked as active. The issue #45 provide more details but in the mean while check the website explicitly by clicking on "Manage Sites ..." and selecting "https://ajax.dev.java.net/eclipse" as shown below ...



Click on "OK" and the list of "Available Software" is now updated to include GlassFish server. Notice, the latest version (1.0.16 in this case) is shown as well.



Select the plugin to be installed ...



Click on "Install ..."



Click on "Next >" and then "Finish". Now your Eclipse is updated with the latest GlassFish plugin.

Lets add a new Server instance. In the "Servers" tab, right-click and select "New", "Server" ...



Select "GlassFish v3 Prelude" after expanding the "GlassFish" tree ...



Name the server if you like or take default and click on "Next".

Notice "Install Server" button, this is the new functionality added in version 1.0.16 of the plugin. Specify a directory name and click on "Install Server". This will automatically download the GlassFish v3 Prelude server and install in the specified directory.



Of course, you need to accept the License ...



Click on "Finish" and GlassFish is downloaded and installed for you (finished in few seconds for me :) and shows the following window:



Clicking on "Next >" walks you through the standard GlassFish configuration options:



More details on how to leverage the powerful GlassFish server are available in the documentation. The screencast #28 shows some of the GlassFish/Eclipse integration features in an easy to use manner.

Please ask any questions or send any feedback to users@glassfishplugins.dev.java.net.

Please leave suggestions on other TOTD (Tip Of The Day) that you'd like to see. A complete archive of all tips is available here.

GlassFish v3 Prelude - now available!

GlassFish v3 Prelude is a modular and lightweight Web 2.0 development and deployment platform. It has been brewing for the past few months and is now finally available - download here! Read the official Press Release for more details.

Use it for deploying your enterprise applications today and purchase production support for the GlassFish Enterprise Server v3 prelude.

Simply unzip the bundle and start the Application Server as shown below (including startup log):

• Modularity using OSGi: OSGi provides complete modularity in the kernel of Application Server. It completely shatters the “one size fits all” philosophy. Basically you pay in terms of memory, resource utilization, learning and everything only for the components you care about. And as your need expands, you can download OSGi modules for technologies from the Update Center. TOTD #36 shows how a standard OSGi bundle can be easily deployed on GlassFish.
• Retain session data across HTTP deploys: 1.Imagine debugging a Servlet that manipulates session data. By enabling a property during redeploy any active sessions of the application that is being redeployed will be serialized and saved in memory, and restored once the redeployment has completed. Read more details here.
• Embeddability allows to run the GlassFish inside a VM – no explicit need to download/install/configure an Application Server. Read more details here and enjoy a live sample.
• Dynamic Languages and Frameworks like Ruby-on-Rails and Groovy/Grails are gaining popularity. These dynamic languages and frameworks are first-class citizens in GlassFish. And integrated tooling (develop/deploy/debug) cycle makes it all the more attractive. Read more details here and numerous samples.
• Faster startup time – Application server startup in 2-3 seconds, need we say more. Think about about the productivity boost!
• Integrated Tooling – NetBeans 6.5 & Eclipse 3.4 provides comprehensive tooling options. By using deploy-on-save technology, Servlets and JSPs are automatically compiled and deployed. This functionality shortens a developer's iterative development experience to edit-save-refresh browser. Screencast #24 shows how to get started with NetBeans (an updated one coming soon). Read more details about Eclipse 3.4 here. Detailed screencasts coming for both the IDEs soon.
• First flavor of Java EE 6 – First access to some of the Java EE 6 spec implementations are available through the bundled Update Center. JAX-RS 1.0, JSF 2.0, EJB 3.1 to begin with and more will be pushed as we make progress.

• Getting Started with GlassFish v3 Prelude using NetBeans 6.5 and Eclipse 3.4
• Web Application develop/deploy/debug session using NetBeans 6.5 and Eclipse 3.4
• Create/Run/Debug Rails application on GlassFish v3 using NetBeans 6.5
• Retain Session data across HTTP deploys using NetBeans 6.5 and Eclipse 3.4
• Creating an OSGi bundle and deploying on GlassFish v3 Prelude

GlassFish on Eclipse Ganymede

Eclipse Ganymede is the annual release of Eclipse projects; this year including 23 projects. Screencast #WS6 showed how GlassFish v2 can be easily registered and started within an earlier version of Eclipse (3.3 specifically). Eclipse is now 3.4 (as part of Ganymede) and GlassFish v3 is blazing the community with it's modular, embeddable and extensible architecture.

GlassFish v3 TP2 on Eclipse

Screencast #WS6 showed how to configure GlassFish in Eclipse IDE. With GlassFish v3 TP2, the plug-in is also updated. Here are snapshots showing how easy it is to install GlassFish in Eclipse. The snapshots follow the steps outlined in screencast #ws6 anyway.

Download Eclipse IDE for Java EE Developers and install. Check the version ...



... add a new server (in order to install GlassFish adapter) ...



... click on "Download additional server adapters" ...



... select "GlassFish Java EE 5 Server" adapter ...



... click on "Next >" and follow the steps ...



... the IDE restarts after adapter installation is complete. While the IDE is restarting, download GlassFish v3 TP2 and unzip (single zip for multiple platforms). After the IDE is restarted, add a new server (following the steps above) and filter on "glassfish" ...



... click on "Next >" and select the location of GlassFish v3 TP2 installation ...



... click on "Finish" to see the following window ...



... click on sideways white triangle in green circle to start GlassFish and see the output console as ...



See how GlassFish starts up in less than 1 sec - and it is modular (OSGi compliant), embedable (run in-VM) and extensible (non-Java apps).

And as Ludo reported, it also runs in embedded mode.

GlassFish Book Review

A book on GlassFish: "Java EE 5 Development using GlassFish Application Server" by David Heffelfinger, was released last month. The publisher sent a courtesy copy for review, thank you for that. I read good part of the book on my several flights in past two weeks. First of all, I'd like to thanks the author, publisher and rest of the team for writing this book. Overall I liked the book because of it's simplicity and a good flow through out the book. This is a great book for first timers!

Here are some of the points that I'd like to highlight:

1. Community is a very strong aspect of GlassFish. And "Who's Who ?" of this book endorses that point. The Author, Reviewer, Editor or anybody else is not involved with Sun. That is a good community feeling and we hope to see more books on the similar lines with a different perspective.
2. The GlassFish-specific notes sprinkled through out are very helpful. Even though the book is mainly about Java EE 5 concepts but the notes allow to think from GlassFish perspective. For example, there are GlassFish admin console screenshots at relevant points.
3. The book uses simple English to explain the concepts. The flow of the chapters is easy to understand and very good for the Java EE 5 first timers. This is very clearly marked in the beginning sections of the book which says "This book is aimed at Java developers wishing to become proficient with Java EE 5, who are expected to have some experience with Java and to have developed and deployed applications in the past, but need no previous knowledge of Java EE or J2EE. It teaches the reader how to use GlassFish to develop and deploy applications."
4. Some book authors take the approach of building a complete application from scratch and explain the concepts using that application. This approach typically requires to understand the application and the actual technology details may get lost. I personally like the Hello World approach with small and simple samples. This book follows that approach and I personally feel it's more beneficial where the readers can focus on the technology.

Here are some potential improvements:

1. The first chapter provide a very simple explanation of GlassFish installation with different screenshots. The different alternatives to deploy and undeploy an application are discussed in very simple language. However only the asadmin-way to create JDBC connection pools & resources is explained. It would be nice to provide asadmin commands to do the same tasks as well.
2. NetBeans and GlassFish integration is explained in 2 pages only. The NetBeans IDE provides a much tighter integration with GlassFish including deploying/undeploy apps, monitoring and configuration. Multiple screencasts and docs explain that relationship already but it would be nice to provide a slightly more detailed overview in this book. OTOH, Eclipse integration is still using an older version of Eclipse. The screencast #ws6 shows how Eclipse 3.3 can be used to integrate GlassFish and create simple applications.
3. I understand the time/resource balance but feel the Web services chapter is pretty minimal. It merely introduces the basic Web services support in GlassFish and does not talk about about any of the Security, Reliability, Transactions and .NET 3.0 interoperability. Anyway, you can find the details in tutorial and numerous screencasts about Metro (the Web services stack in GlassFish).
4. A minor nitpick - The GlassFish on the book's main page is looking right where as the GlassFish logo is looking left.

Send feedback to feedback@packtpub.com, making sure to mention the book title in the subject of your message.

In a nutshell - Great book, must buy for first timers, buy your copy here.

Happy reading!
