1. This can't be the complete jsp code. If it is, you need to minimally
wrap it in <%   %> markers to indicate it's raw java code, not
jsp/html. Additionally your System.out.println() call would end up
going to the JVM's standard output instead of the browser.

2. The listed exception is really secondary to the main problem
occurring whenever the jsp compile fails to generate a .class file.
There has to be an earlier exception detailing the syntax problems with
the jsp.
