Answer 1

I fought with this problem for a while. I got it to work, although I'm completely satisfied with the method.
The problem, I think, stems from a mismatch between the J2SE version Jdeveloper is using and the Tools.jar. I started using J2SE 1.4.1 recently (which I installed via project setting - libraries - define)and this problem cropped up. I tried changing out tools.jar in my jdev/jdk/lib directory with the one from JDK 1.4.1 but to no avail.
I went back to 1.3.1_02 and restored tools.jar and the problem went away.
Hope this helps in some way.
