MyEclipse is integrated with Eclipse, and embarrassingly I don’t know the answer to your “Eclipse or MyEclipse” question. My invoking string is…
C:\eclipse\eclipse.exe -product com.genuitec.myeclipse.product.ide -vmargs -Duser.language=en -Xms128M -Xmx512M -XX:PermSize=64M -XX:MaxPermSize=128M
And, when I start Eclipse this way, it errors when it can’t find the IncrementalJspBuilder class.
