Cheap Servlet Hosting?

deander2 asks: "I'm a Web developer specializing in Java servlets. I'm looking for a basic Web-hosting solution that can (cheaply) provide e-mail and the ability to test and run my own personal programs. However, everywhere I go the only packages available with servlet options cost $80+/month, MUCH more than justified for a personal Web site. I ask Slashdot: Are there any hosting companies which offer personal Web hosting with servlet capabilities in the sub $20/month category? Am I asking too much here? Is getting a corporate account the only way to go if I want to show off my work?"
