I've prepared an Eclipse project, with JBoss IDE Packaging configuration for an
EAR file that deploys a portlet instance of the "Guess a Number" sample
application from the jboss seam source.
It works with the following configuration:
JBoss AS 4.0.4RC1 from source in JDK 1.5
JBoss Portal 2.4 from source ( it might work with 2.2.x also )
JBoss SEAM latest from source
JBoss EJB3 implementation (part of AS 4.0.4RC1)
JBoss jBPM as packaged in SEAM (jBPM 3.1.1)
Facelets and MyFaces as deployed in Portal 2.4 for administration.
The key differences between this and the standard Guess a Number sample
application are in the following areas:
1) View pages
I've re-tagged the view pages as Facelet based view definitions instead of JSP
based view definitions.
2) Bean implementation
I've changed the numberGuess class to be EJB3 Bean based. It is packaged in a
sample-portlet-bean.jar for demonstration purposes.
3) Packaging configuration
All of the standard JBoss and JSR 168 portlet descriptors are included in the
packaging.
It is packaged as an EAR file - with a single bean JAR, and and a single web
app WAR file. The jboss-seam.jar file is packaged in the EAR file, along with
the jBPM-3.1.1.jar file and both are classpath'ed in the MANIFEST.MF that is
packaged in the WAR and JAR files.
The full packaging-build.xml for JBoss IDE is included in the Eclipse project.
You will need to adjust the paths for your local install of Seam and also the
library references will need to be adjusted for your local JBoss install.
4) Changes to faces-config.xml
The following faces-config.xml changes are necessary:
| <!-- Facelet Portlet View Handler -->
| <!-- Critical for Facelet Portal Support -->
| <application>
| <view-handler>
| com.sun.facelets.FaceletPortletViewHandler
| </view-handler>
| </application>
|
| <!-- JSF Phase Listener for SEAM based Portlets -->
| <!-- Install's Seam Contextual compoent support for Portlet -->
| <!-- Critical difference from standard Seam Application -->
| <!-- deployment. -->
| <lifecycle>
| <phase-listener>
| org.jboss.seam.jsf.SeamPortletPhaseListener
| </phase-listener>
| </lifecycle>
|
And the following changes were made in web.xml to allow for both the switch to
an EJB3 based logic layer :
| <!-- JNDI name pattern for EJB3 (change for other servers) -->
| <context-param>
| <param-name>
| org.jboss.seam.core.init.jndiPattern
| </param-name>
| <param-value>
| sample-portlet/#{ejbName}/local
| </param-value>
| </context-param>
|
And the following change - commenting out the the StartupServletContextListener
- is the only other difference from a standard Seam web.xml configuration.
| <!-- MyFaces Context Listener -
| Commented out because Portal
| Loads this Context Listener
| <listener>
| <listener-class>
| org.apache.myfaces.webapp.StartupServletContextListener
| </listener-class>
| </listener>-->
|
I have posted the project to box.net for now (I am out of town, and can't get
at my machine to post it on my own server).

If there is a JBoss.org location for something like this, I can also post it
there. Outside of that - if you can't access it from box.net - let me know and
I'll find another way to get it to you.
Thanks
