Despite I added all necessary .jar files to project, I always take boring exception warnings that say "class not found". I added the code and exception output below. I'll be so happy if someone can help me.
Are you deploying all the dependencies of those libraries? I thought Hibernate had a number of other dependencies.
In any case, I'd both (a) make *sure* you're deploying the libraries you believe you are, (b) make sure the transitive dependencies are also deployed , and (c) turn debug logging on and check your application startup logs to determine the root cause of the failure.
