(In reply to comment #0) First time I installed Helios, I used to have this problem as well... but now it seems to work. I don't remember if I've updated Helios or not... maybe it's been fixed... Good luck!
I have recently had the same problem with Helios SR 2. I am simply doing the other user's step 4: 4. on web project select Export -> War File Below is my stack trace.

I just experienced this issue myself and was able to discover why it happened to me. I had a User library where I updated some of the jar files. I did the update by simply replacing the files in their directories with the newer versions. I had Eclipse open when I did this. Some of my projects that referenced this library started showing this error. I did not connect the two since they happened several days apart. Once I closed Eclipse and reopened, I got some build path errors that I tracked to the change. Once I removed and readded the updated jars, the error went away. Just wanted to let you know that changing jars in a User library outside of Eclipse while Eclipse is open can lead to this error.
