That problem indicates that you have incompatible versions of javax.crypto.spec.SecretKeySpec. This happens when you try to serialize an object of a particular class and the serialVersionUID is different on the the receiving end of the socket. You need to be sure that javax.crypto.spec.SecretKeySpec is the same on Tomcat and WebSphere, which it wouldn't be in your case since Tomcat 4.1 uses Java 1.4 and WebSphere 3.5.6 uses 1.2 I believe. I don't believe that SecretKeySpec was around until 1.4. Is the exception being thrown in WebSphere?

The Exception is thrown in Tomcat and not in Websphere.
I agree. Here's the link: http://ej-technologies/jprofiler - if it wasn't for jprofiler, we would need to
run our stuff on 16 servers instead of 3.
