Don't repeat yourself. If someone here knows, you'll get a response.

And what made you think this is a 'Java Announcement' anyways?

db

Linux:
which java
or
echo $JAVA_HOME

Windows:
type "set" <enter> at the command prompt. This will scroll a bunch of text, look for the "java" in your path
or
echo %JAVA_HOME%
or echo %PATH%
