Debug level Hibernate log excerpt:

I was trying to run the example defined in the refrence.pdf in chapter 2. Not sure what lib/jar file is missing, since I included all the requested jar file in the class path. This example does not seem to require any J2EE server running.

Thanks

Hello i'am new user of Hibernate.
I have the same problem. Can you help me please?
Thanks

What jar is this class in:

org/javagroups/MessageListener

You need it if you're using it. And where is that JAR on your classpath?

This is why I hate tutorials that ask you to download a bunch of jar files and use a bunch of code that hides what is really going on. It's just not a sound way to learn. Sorry for the editorializing, but it really bugs me when people are trying to learn, but the resources make it impossible.

If you want some good learning resources, follow my signature links. You won't run into these types of problems.
