I just ran into this problem that eclipse wouldn’t display the J2EE module dependencies for a couple of my projects. The solution I found was to open the MANIFEST.MF files for those projects and delete the classpath entries. I suspect I had some old classpath entries in there which were no longer valid, and the property page code was flipping out about it.
Hope this helps someone …

Well that definitely helped me a lot.
I’m using “BEA WorkSpace Studio Version: 1.1″.
And in that some of my projects were not displaying the entries in J2EE Module Dependencies saying it has invalid entries.
Thanks a lot

Thank you! This helped me to resolve the problem with RAD 7.0 (Rational Application Developer). But … I had to make a restart after replacing the MANIFEST.MF file.
