In Java, variables that are not Java primitive types (like int, long, etc.)
are *always* references to objects (they act basically like pointers in C and
C++). Thus, session.getValue("mybean") will return a reference to exactly the
same object you originally stored in the session -- it does not create a
clone.
If you are not seeing this behavior, then you are doing something wrong --
probably with how your "session" variable is getting set. We'll need to see
more of the code to help figure out what's happening.
