It turns out to be a documentation problem with Hibernate 3.0 in that one of the required jar libraries is not documented as being required. Once I added the asm.jar library, everything started to work properly. -david- - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
