While trying to debug a servlet I get an error dialog (no details other then “Error”) regarding the source display. No source is displayed and the log has the following exception in it.

The container is Tomcat 6 (not the MyEclipse Tomcat). First I thought it was a class/VM mismatch, but I have tried many variations of JDKs for both the project and the container with no success.

Any ideas would be appreciated. Thanks …

This is happening on any Java I try and debug not just servlets.

[mikewener]

I found the problem. I had an incompatible JRE in my path.
