Java on RH enterprise 4

[Michael Scully]

John:

	If the application can be pegged to a particular version, you can install as many different revisions of Java as you like.  You can download all of the archived versions from Oracle if you create a developer account.

	Java will install to /usr/java, with each version in its own directory.  Look in there to see what version(s) you have.  But if you need the /usr/bin/java to point to a particular one, change the symbolic link of any of the java command links there (java, javaws, javac, javadoc).
