Classloader or Security Issue?

[Suneet Shah <su...@gmail.com>]

Hello,

I am trying to call an EJB from tomcat 5.5.20. The EJB is is located on
Websphere 6.1. I am able to get the JNDI context, but when I lookup the
bean, I get the exception below. I confirmed that its not a classpath issue
as the ibmorb.jar, which contains the UtilDelegateImpl class, is in the
common/lib directory in tomcat. This problem is only happening on Solaris.
Both tomcat and WAS 6.1 are on Solaris. When I run this on Windows, it works
just fine.

Any thoughts on what this could be and how I can get around this?

Thanks in advance.

which JDK are you using on Solaris?
SUN JDK (version)
IBM JDK (from the WebSphere AppClient, version?)
