For a jre you could create a file called /etc/profile.d/java.sh containing the following (JAVA_HOME path will need to point to the correct directory for your particular Java version):

#!/bin/sh
JAVA_HOME=/usr/java/jre1.5.0_08
export JAVA_HOME
JAVA_BIN=$JAVA_HOME/bin
CLASSPATH=$CLASSPATH:$JAVA_HOME:$JAVA_HOME/lib PATH=$JAVA_BIN:$PATH
export JAVA_BIN CLASSPATH PATH

Before I do that, I would need to remove the gcj stuff that are in /usr/bin. If I know how to remove gcj, I'd gladly do that. However, for the particular version of the OS, the entire GCC seems to be bundled into one rpm, and I could not remove just the gcj component. Neither do I wish to mess with files that are part of some RPMs--- in my experience that's invitation for trouble later.

Best,
Andy
