I am not familiar with JWS. But this might be of help for ClassCast Exception.
The servlet engines normally use their own custom classloaders. The classes
available from System CLASSPATH environment variable are loaded using System
ClassLoader. If you try to set an object from a servlet to an object loaded
from the System Class Loader, you get the other error. So check up to see if
you are doing so.
