I am calling EJB service in my code. It is working fine with web sphere WAS 7.0. But when tried to run the same code in WAS 8.5, am getting the below error.
Error 500: javax.servlet.ServletException: javax.naming.CommunicationException [Root exception is java.rmi.UnmarshalException: error unmarshalling arguments;
nested exception is: java.lang.ClassNotFoundException: com.ibm.osgi.jndi.fep.GatewayBundleContextProxy:
This error could indicate that a component was deployed on a cluster member but not other members of that cluster. Make sure that any component deployed on a server
that is part of a cluster is also deployed on all other members of that cluster]
How to resolve this issue? Why it is not working in 8.5?
