Problems running WebSphere® Pluggable Application Clients on the same host machine as WebSphere Enterprise Edition
 Technote (troubleshooting)
 
Problem(Abstract)
In testing the WebSphere pluggable application client on a host machine where WebSphere Application Server Enterprise Edition was also installed, exceptions occurred during Object Request Broker (ORB) initialization. However, the client did continue and complete.
 
Cause
The workload management (WLM) plug-in for the ORB is different, if you are accessing the Enterprise Edition server instead of the Base or Network Deployment editions. The WLM plug-in also has some different requirements for accessing an enterprise bean from a WLM client through Remote Method Invocation Internet Inter-ORB Protocol (RMI/IIOP).

The following exceptions occurred:

Resolving the problem
Modify the BOOTCLASSPATH to pick up the appropriate Java archive (JAR) files that are required for the Enterprise Edition. After placing the following JAR files in the BOOTCLASSPATH, no exceptions occur:
