ClassNotFoundException on WAS 5.1.1.4

Hello

My app is on a WebSphere Application Server Base 5.1.1.4), AIX

The probleme is: everything works fine (during one week, one day or one hour) until I get a ClassNotFoundException.

My application tries to load classes with a Class.forName(className)
instruction every time it gets an XML message (the XML message contains the string className).
All the classes of my app are in a jar (in the WEB-INF/lib folder of my ear).

Most of the Class.forName are successful, but some failed I dont know why.
I traced all the package com.ibm.ws.classloader, check the classloading in
verbose mode but I cannot resolve the problem.

When I restart the server, all is normal until a ClassNotFoundException on a random (never the same class) class appears.

Here is the trace.log:

Try and replace your JAR from WEB-INF/lib into WAS's classpath. I've experienced similar problems with WAS 5.0, even if in my case the problem was about marshaling and not classpath...

Claude.
