How about e.printStackTrace()? Post the entire message and full stack trace.
I can see a whole bunch of things wrong with your original code:
1. You re-register the driver for every request (Class.forName) which
isn't that big of a deal... just a waste of time at least for the
MySQL driver. It's mostly just bad coding practice.
2. You create a new Connection for every request. You would be much
better off using pooled connections. Look at the Tomcat documentation
for using JNDI DataSources.
3. You swallow nearly all exceptions. At least log them.
System.err/System.out doesn't count.
4. You shouldn't have any Java code in a JSP (debatable).
5. Everything is hard-coded. Of course, this looks like a test page
so you can be excused for that :)
