Hi,
Thanks for your response,
I get the following error,
Uncaught exception from servlet
javax.jdo.JDOUserException: Persistent class "Class guestbook.Greeting does not
seem to have been enhanced. You may want to rerun the enhancer and check for
errors in the output." has no table in the database, but the operation requires
it. Please check the specification of the MetaData for this class.
