I think that the solution for this exception is to create a 
serialVersionUID member in the Serializable bean or class that you 
wish to store in a session.  This is easily accomplished using the 
serialver tool that comes with the JDK.  You run this command with 
the full name of the class that you wish to create a UID for.  It 
outputs the line of code that you should insert into the class file's 
source.  It is a classloader issue.  When you make changes to a class 
and recompile, any older versions of that class that are serialized 
will not be able to be deserialized as the same class without having 
the same serialVersionUID.  Does this make sense?  I am pretty sure 
that this is what is necessary.
