java.lang.NoClassDefFoundError while trying to access portlet over WSRP

Solution Unverified - Updated -


  • We are Migrating from Jboss Portal 5.1 to Jboss Portal 6.1 and getting exception in following scenario when we are trying to access remote portlet over WSRP :

java.lang.NoClassDefFoundError : org/gatein/wsrp/servlet/ServletAccess while trying to access portlet over WSRP because this class doesn't exist in JBoss EPP 6.1

In the earlier version jboss 5.1 it exists in wsrp-common-2.1.5-EPP521-GA.jar

We have portlets deployed on our servers and it is being accessed from a remote portal deployed on a separate machine. The same portlet is working on 5.1 server with similar integration.
