Answer 1

You aren’t running JBOSS; you’re running Tomcat.

The package net.hibernate is pretty old. Hibernate 3 packages all start with org.hibernate. I’d recommend upgrading those right away.

I’d recommend looking at this answer. If you must have JTA, be sure to have the JTA JARs in your WEB-INF/lib and some implementation like JOTM, too.
