Hi Zahid
If you are using windows, open a DOS window and type PATH
It will show the current PATH. Check in that list, whether your JDK1.2.2/bin directory is there or not. This is where all your
java compiler and other utilities exists.
If not add this
<drive>JDK1.2.2/bin like this
for eg. if your JDK is installed under C:\JDK1.2.2
SET PATH=C:\JDK1.2.2\bin;%PATH%; Cheers
