We have seen this error with users who have installed JDK 6.0. Setting
the tools.jar path should solve this problem.

Select "Edit -> Preferences..." and click on the "..." to the right of
the "tool.jar" field. This will display a file selection dialog.

Now that the selection dialog is open, navigate through your file
system and select your "tools.jar". On Windows, it can often be found
in "C:\Program Files\Java\<jdk version>\lib\tools.jar". If you cannot
find it here, search for "tools.jar" across all your hard drives. On
Linux\Unix and Mac OS X, typing "locate tools.jar" at a command line
can help you locate it.

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?

Are you running DrJava with JRE 1.5.0_04 as well? The compiler and JRE
need to be the same version.

Thank u Chris, the problem has been resolved. Since i ve upadated my JRE to the newest version, Dr java can't recognize the tools.jar file. So I just deleted my JRE and setuped an older version, everything seems fine now
