Portlet Invalid handle exception -- URGENT PLEASE HELP

Question

I am deploying our Portal application and portlets in a clustered environment. We have three machines and following weblogic servers are started in each machine:
Machine1 - Admin Server
Machine2 - Portal1, Portlet1
Machine3 - Portal2, Portlet2
Portlets are deployed on portlet servers (portlet 1 and portlet 2). When I deployed the Portal application I intentionally registered portlet producer pointing to 127.0.0.1:8889, thinking that it will work for both portals since the portlet server is in same machine as well..
So my assumption is :
Portal1 will always load portlet from Portlet1 server and
Portal2 will always load portlet from Portlet2 server
but I am getting following error now... don;t have a clue what to do.. This is very urgent, I am working over the weekend over this.. any help would be highly appreciated..

Answer 1

Sak007,
Did u get the solution for this issue? I am also facing the similar kind of issue.
I have a portal server, that consumes the remote portlet which is deployed on a cluster environment (Server1 and Server2). When i register my remote portlet, sometimes the registration handle holds info about server1 and sometimes it is server2. When the registration handle holds info about Server1, my application is working fine in the portal. Whereas when the registration handle holds the info about Server2. It throws the exception as:
Invalid handle "C:10.10.0.42:-a3eb70c:130d71f8067:-7ff9".[[
oracle.portlet.server.containerimpl.ContainerObjectNotFoundException: Object named "registration" could not be found in the persistent store.
at oracle.portlet.server.containerimpl.persistence.SimplePersistentStorage.get(SimplePersistentStorage.java:47)
Any pointers will be helpful.
Note: I have visited the URl posted in above thread and it doesn't solve the issue.
Thanks.
