Any one can give some suggestion the pros and cons for each version?
I am using 3.3 now. Thinking of using 4.0 for it. What should I do and does it worth to have some hassle to upgrade it? Thanks!

Depends on what you want to do. Version 4 supports the latest JSP & Servlet APIs, so if you're planning on using any of that functionality (filters, session listeners), you will need v4. You won't have much of a hassle upgrading...

To be specific, Tomcat 3.3 runs on Servlet 2.2/JSP 1.1 while Tomcat 4 uses Servlet 2.3/JSP 1.2.
