I would not expect CVS to have any impact on JSP debugging. Unfortunately we need more info to gain insight into your problem. Please review the posting guidelines for the basic info we need to assist you: http://www.myeclipseide.com/index.php?name=PNphpBB2&file=viewtopic&t=394
1) Describe how you are deploying your webapp
2) Verify that the Tomcat connector is configured to launching debug mode.
3) Within a JSP file where are you setting breakpoints, e.g., html content, scriptlet, include JSP.
4) Anything else you can think of, e.g., the problem only appears when facing east or listening to Rush at a high dB level 🙂
