java.exe has generated errors

Hi all,
I have installed JRE 1.2 and Jdk 1.2.2 on my new machine (Pentium 4 ) with Windows 2000.
When i am running the java.exe or javac.exe from command prompt , I am getting following error messages.
"java.exe has generated errors and will be closed
by windows. You will need to restart the program.
An error log is being created."
Can any one experienced it and how to fix it.
regards
VanD

is there a special need for jdk 1.2 cause this one is rather old (beside it should also work). I think you can run in some problems when you want to develop new applications. Try to install jdk 1.4.2 then you are up-to-date.
