[jboss-user] [JBoss Portal] - HelloWorldIPC example not working with JBoss-Portal 2.6.4

[elihusmails]

I downloaded and tried out the HelloWorldIPC portlet example.  I am using version 2.6.4 bundled with JBoss 4.4.2.GA on Windows XP.

Is there any documentation and/or a working example for getting this working?

Here is a snippet of the stack trace:
