[Claude Cundiff]

Hello everyone. I'm trying to run my first Hibernate 3.0 program. I've searched the world of google but I'm still stuck. Any assistance is greatly appreciated! My apologies for the length.

hi,

remove <session-factory> tag and </session-factory> from hbm.xml file,and check it,

regards,

[Claude Cundiff]

Good catch!

However, I'm still getting the same stack trace

[aswin kumar]

hi,
have you saved and executed again? the same error will not repeat .

regards

[Claude Cundiff]

Here is the stack trace after making the suggested adjustments:

I figured the InvalidMappingException problem. It was in the book.hbm.xml. Here is the new version.

Now it throws a HibernateException (JDBC driver not found)

...slowly getting there.

Hi,

just check whether you added mysql driver jar file in your classpath,

regards,

[Claude Cundiff]

I added the driver and got it up and running. Had to work the DoIt class a bit but finally!

Happy New Year!
