Use the nosrc packages from the JPackage project to create and install
an RPM of the JDK you wish to use.  I have done this successfully for
the Sun JDK 1.5.

JPackage is at:

	http://www.jpackage.org

and the Sun JDK 1.5 nosrc RPM is at:

	http://www.jpackage.org/rpm.php?id=2663

the IBM JDK 1.4 nosrc RPM is at:

	http://www.jpackage.org/rpm.php?id=2096

Instructions for converting a nosrc RPM into a binary RPM:
