I don't know of a way to list
invalid sessions, but I do know how
to solve your problem.
Create a class that implements
SessionBindingListener
which includes the method valueUnbound().
Add a String variable for the
filename.
Whenever you create a temp file,
put one of these into the session.
When the session expires the
valueUnbound() method will be called. Use this to delete the file.
