It means, that the ResultSet object you're getting cannot
be passed to the client because it is not serializable.
Generally it is bad style to try this as this gives your
client a direct database access.
One solution is to copy the data of the resultset into
as custom data structure (e.g. a java.util.List of FooDataObjects)
and pass this structure to your client.
Have a look at the mail-archive the www.theserverside.com,
you should find some more info to this topic there.
