This sure does sound like a class loader issue. Possibly the EJB container instantiated the $Proxy133 object with one class loader and your code is using a different class loader, so even though both of the class loaders have the interface declaration, those interfaces are not the same.

I suggest moving the EJB JAR file out of the WAR file and placing it into the deploy directory. If that works, you can always repackage your app as an EAR containing the EJB JAR and your WAR.
