At this time, I do not believe that there are plans to implement JSR-168 on JBoss (AFAIK). However, you can try the eXo SourceForge portal server (it has a deployer for JBoss-Tomcat, I believe).
Thanks for pointing out the EXO platform and its plugin for eclipse.
I was looking for some sort of functionality to create and deploy a portal site using eclipse...
I hope that MyEclipse will be integrating portals/portlets very soon and that more application servers like JBoss will support JSR 168 so that we can use the connector withing MyEclipse to test/deploy portals to JBoss.
Keep up the good work Guys!!!
