Where is the Java runtime .jar?
What is the name and what is the location of the Java runtime .jar file?
I'm trying to find this because of a conflict between Mathematica (version 8.0.4) and McAfee Security. Apparently, on-access scan of some Java-related files i preventing necessary communication between Mathematica's "front end" and its "kenel" calculating engine that uses Java for the communication. And definitively turning off McAfee on-access scan allows the communication whereas enabling it (the normal state) prevents it.
