Hi,

I am having trouble getting IPC working between portlets.  The test event 
portlet in the default portal application works.  I am running the following 
software versions:

  | jboss 4.0.4 CR2
  | jboss portal 2.2.1RC3 built from src using jdk 1.5.0_06
  | 
  | 
  | First, I started with my own portlets, but then I downloaded the 
HelloWorldIPC.zip portlet from PortalSwap 
(http://labs.jboss.com/file-access/default/members/portletswap/downloads/portlets/samples/HelloWorldIPC.zip).
  I am getting the same error with the HelloWorldIPC portlets as with my custom 
code.  There are no deployment errors when deploying the .helloworldipc.sar 
file.

  | I've tried including more library files in the .sar, but it doesn't seem to 
make a difference.  Obviously, it has something to do with the fact it is an 
external .sar and not integrated with the portal app.  It looks like one of the 
.jar files is missing, but I have include every portal-*.jar file I can think 
of in the .sar/.war lib.
  | 
  | Any ideas?
