["J.Hwan.Kim" <j.hwan.kim99@gmail.com>]

Hi, everyone

My system is lenny 5.03 and when I installed eclipse, the development 
tools are installed, too.
But now I want to unistall the java development tools of eclipse. So, I 
did it, but the  java tools of eclipse is not installed.
When I overwrite sun java packages, the java tools of eclipse remains.
How can I uninstall the java tools for eclipse completely?

Thanks in advance

Best Regards,
