Hmm... that's going to make it pretty hard to debug. Any error message
along with the InvocationTargetException itself?
This kind of thing usually happens because of some tiny misconfiguration
of a JNDI DataSource, but it looks like you are probably registering the
driver yourself. Can you give us a bit larger code sample?
If you are able to modify the code, you could just put a try/catch block
around the Class.forName(...).newInstance() line and print any
InvocationTargetExceptions thrown to stdout:
try { Class.forName(...).newInstance(); }
catch (InvocationTargetException ite) { ite.printStackTrace();
throw ite; }
WTF JAR file placement, make sure that your Connector/J JAR file is in
common/lib and /nowhere else/: check your webapp. Check shared/lib.
Check server/lib. Check for multiple versions of the same driver (like
mysql-connector-3.1.4.jar AND mysql-connector-3.1.5.jar).
Also, Connector/J 3.x is super old. Any chance of upgrading? They're on
5.1 these days...

If the error is happening on the server, then you'll have a hard time
getting a client to give you the full stack trace: you'll have to check
the server's logs.
