Subject RE: serializable class not persisting (long email)

hmm, looks like a tomcat problem for sure. what happens if you stop the
context and the start it again, instead of initiating a reload.

does that make a difference?

putting the classes in common/lib is not a good solution if you want to
update them without stopping tomcat
