First, you need to run Tomcat in debugging mode. The easiest way to do that is to modify the startup file (.bat or .sh depending if you are Windows or not). Find the line near or at the end of the file that contains the start command, and change it to jpda start. This will cause Tomcat to start in debugging mode listening on port 8000.

Next, to connect to this process via Eclipse, select the Run menu and choose Debug Configurations.... In the pane on the left, choose Remote Java Application and click the New launch configuration button above the list. The important settings to note are the Host and Port fields. The host value must match the hostname of the Tomcat process, and the port should be 8000. You also might need to add entries on the Source tab to ensure that all of the source code is available to step through.
