What JVM are you running in the Ubuntu VM?
Make sure that you are using a Sun VM, not the GNU dito that often is distributed with Linux etc.
In one case I had to completely delete the GNU VM to resolve the problems I had.

Thank you Ivan. Your answers have been really helpful for me!
I'm also using your study notes to learn about securing web services.They are excellent.
I did what you said regarding this problem, but it could not solve it.
I also tried with a simple web service (with no hibernate nor connection to a db) and it worked fine.
It is only the web service with hibernate that doesn't work on my Ubuntu installation.
Any ideas of what I should do? or any advise of how I can troubleshoot this problem?
Thank you very much!

Regretfully, I have no idea where the problem may be but, if I were in your situation, I would try to run some other, non-web service, program that uses Hibernate in the same way as the web service in your Ubuntu VM. If possible, try make this test program a standalone program, that is, a program that does not need to run in a container.
