Hi myself ;),
Forget my last post. I remembered my experience with RMI and checked
that my Bean was really serializable, it wasn't. Even though the class
is found, sometimes non seriable classes that should be serializable
give this "Class not found" exception so in case it helps somebody, the
mantra I learnt from RMI is that "A class is serializable if it
implements Serializable AND all it's members in RUNTIME are either
transient or serializable". This usually gives people headaches when non
serializable elements are put inside hashtables in runtime, the class
then becomes non serializable. I hope somebody can benefit from this
experience as well.
Regards,
Dan
