Well, the PATH variable usually contains the following by default
Code:
%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem
And you just have to append the path to Java bin directory to the existing value present in the PATH variable, like this
Code:
%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C>:\J2sdk1.4.2_13\
I hope you got it this time.
