You should try rebuilding the Jpackage "nosrc" rpm of the Sun JRE and
installing that, instead of using the JRE directly -- instructions at
http://www.jpackage.org/rebuilding.php

Once you've done that, you can change where the "alternatives" link
for java as follows (as root):
    /usr/sbin/alternatives --set java /usr/lib/jvm/jre-1.5.0-sun/bin/java

Then "/usr/bin/java" will be the Sun JRE, and all your apps should use
it by default.

There's no GUI config tool for alternatives, is there; it would be nice ...
