Ultradev and PostgreSQL on SuSE

Hi

I'm using JDBC driver to connect Ultradev to postgresql database and
everything works fine but when I try to open the index.jsp file with
a web browser I get these:

Error: 500

Location: /phone_book/index.jsp

Internal Servlet Error:

I'm not sure where to look at to fix the problem.
Any help is highly appreciate.

Thanks
