Hechun,
This is really a question for the Hibernate forums, not MyEclipse... I'm not saying this because I don't want to help, but becuase I don't know and it really is an issue dealing with hibernate functionality and the oracle driver. I'm sure people that have run into this can help you more effective there.Hechun - Nov 08, 2004 - 05:29 PM Post subject:
OK, Thanks.
