Tomcat is an open source servlet runner which aims to conform to the latest servlet and jsp specifications.

I contributed a Securing Tomcat article to the OWASP to help system administrators setup tomcat securely.

If you are looking to roll out a web application and want to use JNDI to allow customers to configure resources easily, you can! I found the documentation a little confusing though, so I wrote the following article on Configuring JNDI Resources in Tomcat.
