16:25:26,828 INFO [STDOUT] me closing the session

Name and version of the database you are using:Firebird 1.5

The generated SQL (show_sql=true):No SQL generated .. the error is thrown before hibernate session saves the object

Debug level Hibernate log excerpt:


I can read from the table. The problem is when I try to write .. I am getting this error messages as Table unknown. Am I missing any jar files .. it seems something is fishy in creating generator ...

I did spend couple of days on this .. any help/hint appreciated.
Thanks.
