TOTD# 86: Getting Started with Apache Wicket on GlassFish

This Tip style="font-weight: bold;">Of style="font-weight: bold;">The style="font-weight: bold;">Day (TOTD) shows how
to create a simple Wicket application and get it
running on GlassFish:

1. Create a Wicket project as:
   
   
   
   style="text-align: left; background-color: rgb(204, 204, 255); width: 100%;"
   cellpadding="2" cellspacing="2">
   ~/samples/wicket
   >mvn
   archetype:create -DarchetypeGroupId=org.apache.wicket
   -DarchetypeArtifactId=wicket-archetype-quickstart
   -DarchetypeVersion=1.3.6 -DgroupId=org.glassfish.samples
   -DartifactId=helloworld

   instead

2. Run it using the pre-configured Jetty plugin as:
   
   
   
   style="text-align: left; background-color: rgb(204, 204, 255); width: 100%;"
   cellpadding="2" cellspacing="2">

   And the default web page is available at
   "http://localhost:8080/helloworld" and looks like:

   A later blog will show how to run this application using href="http://embedded-glassfish.dev.java.net/">Embedded
   GlassFish. But for now lets package the application as a WAR
   file and deploy it on GlassFish.

3. Download href="https://glassfish.dev.java.net/downloads/v3-preview.html">GlassFish
   v3 Preview and unzip.
4. Create a WAR file as:
   
   
   
   style="text-align: left; background-color: rgb(204, 204, 255); width: 100%;"
   cellpadding="2" cellspacing="2">
   ~/samples/wicket/helloworld
   >mvn package

   [INFO] Final Memory: 14M/80M
   
   [INFO]
   ------------------------------------------------------------------------

   
   
   and deploy as:
   
   
   

   style="text-align: left; background-color: rgb(204, 204, 255); width: 100%;"
   cellpadding="2" cellspacing="2">
   ~/samples/wicket/helloworld
   >~/tools/glassfish/v3/preview/glassfishv3/bin/asadmin deploy
   target/helloworld-1.0-SNAPSHOT.war
   
   
   
   Command deploy executed successfully.

   
   
   The app is now accessible at
   "http://localhost:8080/helloworld-1.0-SNAPSHOT" and looks like:
   
   
   
   alt=""
   src="http://blogs.sun.com/arungupta/resource/images/wicket-helloworld-output-gfv3-preview.png">

Cool, that was pretty straight forward!



Now that's a very vanilla application but at least shows that Wicket
applications can be deployed on GlassFish out-of-the-box. A slightly
more complex application will be shared on
this blog in future.



Here are some more useful links for Wicket:

• Wicket
  Quickstart shows how to create a Wicket application and get
  started easily.
• Wicket
  Examples provide a flavor of how the code is structured.
• Wicket in
  Action is a great book that explains the concepts very well.
• May want to look at href="http://www.wicketframework.org/wicket-extensions/index.html">wicket-extensions
  for a list of gadgets/widgets that extend the core capability of the
  framework.

A few related blog posts planned:

• Run Wicket application using Embedded GlassFish
• Use href="http://blogs.sun.com/swchan/entry/servlet_3_0_web_fragment">Servlet
  3.0 web-fragments.xml and leverage GlassFish v3 Pluggability
  to run Wicket applications
• A Wicket version of href="http://blogs.sun.com/arungupta/entry/track_your_running_miles_using">Track
  your running miles application
• Deploying href="http://www.netbeans.org/kb/60/web/quickstart-webapps-wicket.html">Wicket
  applications from NetBeans to GlassFish

In the meanwhile, href="http://forums.java.net/jive/forum.jspa?forumID=56&start=0">let
us know if you are deploying your Wicket applications on
GlassFish.
