Nothing really jumps out at me. Can you indicate which line the nullpointerexception occurs on?
Incidentally, there's a "Code" button on the message editor that can be used to wrap special tags around formatted data such as Java source code or XML. It keeps the message display from messing up your indentation.
An IDE is no substitute for an Intelligent Developer.
What line does the nullpointerexception occur? Is it when you create your preparedstatement? It could be your database driver/data.
Also, think you're supposed to use h:body in your facelets page. xml and doctype declaration? doubt that has anything to do with your problem though.
