Thanks Jean for replying.. No, this complex object just contains a lot of ints,
doubles, strings, 2 vectors, and associated
accessor methods. I tracked down what was being stored in the two vectors that this
object has, and one just contains strings, the
other contains a set of another complex object, (defined in the same package) but this
second object is also serializable and only
contains strings, booleans, and ints. So there are no references to an "Eclipse"
object or any other non-seralizeable objects or
unknown objects. All these class definitions are contained within the jar file that is
registered to the codebase for the RMI
server. Also all these class definitions are stored within jar files that are placed
within the WEB-INF/lib directory of the servlet
context of the Tomcat server.
It was a good thought though :-) but I am still perplexed!.... Marc....
