Try rpm -qa | grep ^j to get a listing of all RPM packages beginning 
with 'j', so you can be sure of the package name.  Then do the "rpm -ql 
jdk" or whatever it turns out to be.

Let me suggest "locate bin/java", as the JVM is almost certainly in some 
bin directory, and this will prevent locate from spewing out the entire 
listing of the java installation.

For speeding things up and reducing the chance of hitting those mounted
directories (if any -- if he's downloading Limewire I'm guessing it's a
home machine, so not that likely he's got NFS going on, but anyway), I'd
suggest "find /opt /usr -type f -name java", as it usually gets
installed somewhere under one of those two directories.

I seem to be obsessed with optimizations today.
