删除JDK报错:Error: could not open `C:\Program Files\Java\jre6\lib\i386\jvm.cfg'

I find it surprising that it's so hard to remove. Anyway, to answer your question, I'd look for and delete:

• c:\windows\system32\java.exe
• c:\windows\system32\javaw.exe

Once those are deleted, you should be fine.

That said, I seem to be able to run GWT in hosted mode with Java 1.6.0_14 just fine.
