Check exception message carefully.

So the problem is not in WebObjects or what software is installed, on the class path, etc.   It simply can’t talk to the database server.  Is it running?  If so, the URL, database name, user name, or password is wrong.  Or if the database supports it, it is refusing connections from that machine.
