I'm guessing that in your experimenting, you set up two projects with overlapping directories... Eclipse does not like this...
At least one person in our group (Rowland) got Eclipse sufficiently confused that he had to re-install Eclipse...
(BTW, I use Eclipse every day on the Ptolemy tree, and it works great).

Thanks for your help, I also tried the method described but I can not get the project compiled, here is what I tried :
tar xfz ptII3.0.2.src.tar.gz mv ptII3.0.2 ptII
export PTII="/home/franck/bin/my_PTII/ptII" cd $PTII ./configure
cd ~/bin/my_PTII eclipse&
File->New Project Project Name : ptII Directory : /home/franck/bin/my_PTII Finish
-->> An error occured while creating the java project Reason : invalid project description /home/franck/bin/my_PTII and /home/franck/bin/my_PTII/workspace overlap
If I change the directory with : /home/franck/bin/my_PTII/ptII
-->> An error occurred while creating the java project See error log for more details. (java.lang.NullPointerException in the .log of Eclipse !)
I tried other thinks but I can only compile and run (make fast install) without Eclipse !
