Using JBoss with Portlet Factory

On several projects I've had to develop portlets using WPF that are deployed to a Websphere Portal environment, but the options for executing in a development environment are a little limited. I can choose Websphere CE, Websphere Portal or Tomcat, and my first choice is usually Tomcat because it has a small footprint and fires up quickly. But in some cases I need to test some portal specific features like wiring or portlet configuration, and this requires a portal server. Websphere Portal is great for a production environment, but running it locally is not practical since it takes so many resources and has a long startup time.

Running JBoss

At one point I was really under pressure to get some work done and I finally gave up on Websphere Portal and turned to JBoss Portal Server (looks like that project has been merged into project Gateln). Unfortunately WPF doesn't have a configuration option for JBoss so I had to roll my own.

Step 1
The platform definitions that show up in the project properties originate from files located in \IBM\Portlet Factory\Designer\FeatureSets\Web-App_7.0.0\Deployment\antscripts\platformdefs (or wherever WPF is installed). All I need to do is add my own file called JBoss.pfConfig, which is a copy of the Tomcat file looks something like this:
wpf.installedappsdir=C:\jboss-portal-2.7.2\server\default\deploy
wpf.serverport=8080
wpf.serverUrl=localhost
wpf.servertype=appserver
wpf.servername=JBoss
wpf.config.antfile=JBoss.xml
wpf.config.publishtarget=publishJBoss
wpf.webxml.file=standalone.web.xml
wpf.autodeploy=false
wpf.configid=3
wpf.description=CreateServerDialog.TomcatDescription


Step 2
The pfConfig refers to an ant file JBoss.xml which lives in \IBM\Portlet Factory\Designer\FeatureSets\Web-App_7.0.0\Deployment\antscripts\publish. Here again I copy from the Tomcat version and make a few changes:
<!--Ant implementation for deploying to JBoss server.-->

<project name="jboss" basedir=".">
 <!-- Target for deploying project to JBoss server. -->
 <target name="publishJBoss">
  <echo message="Publishing to JBoss server..." />

  <!-- Copy project contents to server. -->
  <copy todir="${wpf.installedappsdir}/${project.name}.war" preservelastmodified="yes">
   <fileset dir="${webcontent.location}">
    <include name="**/**" />
    <excludesfile name="${webcontent.location}/.excludeFromServer" />
    <excludesfile name="${webcontent.location}/../.deployment/excludes/allServers.excludes" />
    <excludesfile name="${webcontent.location}/../.deployment/excludes/JBoss.excludes" />
   </fileset>
  </copy>

  <!-- Copy the standalone web.xml file to the server. -->
  <copy file="${webcontent.location}/WEB-INF/bin/deployment/standalone.web.xml" tofile="${wpf.installedappsdir}/${project.name}.war/WEB-INF/web.xml" />


 </target>
</project>
This is the script that the designer will invoke when publish application (V7) or build war for dev testing (V6.1.2) is selected.

Step 3
Well actually there is no step 3, I think that's all that is needed. When I look at my project properties I can now see JBoss as an available server:


There are a few caveats:
- In some earlier versions of WPF, the designer treats the JBoss configuration like Tomcat and strips off the .war file extension. Every time I explicitly deploy I get an error message and have to go back into the properties and put the extension back on. This doesn't happen when auto sync runs, only when an explicit deploy is requested.
- In WPF V7 the designer will complain about a missing exclude file the first time. Just add an empty file named \myproject\.deployment\excludes\jboss.excludes.

  1. Hi Carl ,
    Thats an awesome article, Thank you for that, we know exactly why you wanted a non-websphere portal dev enviroment :-), are there any pointers/guidelines you have for us in order to develop server independent JSR 286 compliant portlet using WPF 7.0 ? that will great information, Thank you once again.

    Ven.

  2. Hello,

    I want to thank you on the share, very useful for us, I'm learning about Jboss Portal Development in this blog. Looking forward to many interesting and helpful articles from you.

    Thanks!
