Tomcat servlet Cacheing

Hi all,
First let me say that I am EXTREMELY new to Java and even more so Tomcat. I am writing my servlets and placing them in the proper directory. I can load them once, but after that, if I make any changes to the file, and recompile it, I must completly restart Tomcat in order to view the changes.
I quesss my question is, is there anything that can be done about this. It is very frustrating to have to restart the server everytime I change something during development.
Thanks

Tomcat has a management application that lets you start and stop web applications - it is documented in the Tomcat installation - see Manager App from the documentation index page (a good page to get familiar with.)
