I don't know will the package ibm-java2-i386-jre-5.0-9.0.i386.rpm give you what you want because I never used it.I use Sun's jre which you can download from
here (the latest version is Java Runtime Environment (JRE) 5.0 Update 17) if maybe that's what you'll need.
You can try to change default version of jre on the system with this command;
Code:
/usr/sbin/alternatives --config java
Maybe a few more steps will be necessary to change default version of jre but only if the above command gives you any error/s.
