Visual Editor problem in Eclipse 3.2

Helo, I install Visual Editor vi Callisto in Eclipse 3.2 but when I try
to add Visual Class to my project I get:

IWAV0138E Remote VM terminated too soon. See .log file for trace of
output. For VM "Project (c)-VM for c".

does anyone knows what couses this error
in log file:
