Re: having a problem with Dr Java

thank u for replying, but I have already done this and the problem is still there, I downloaded Drjava and ran it, then I go to "edit"> "preferences" >"resource location" and locate Tools.jar Location to C:\Program Files\Java\jdk1.5.0_04\lib\tools.jar.
that's how I set up it, and I have already installed JDK 5.0 update 4 on my computer, as well as JRE 5.0 update 10. Are there anything wrong with my setup?
