Linux, multiple versions of java

I am using RHEL  6.4

If I have multiple versions of java, and I want to make one of the versions that is not the currentl primary version to become the new primary version, is there an easy way to perform this ?

Thanks

cd /etc/alternatives
ln -sf /path/to/your/new/java/location/bin/java java


That will create a symbolic link to the location of your new java and remove the old one.

You can find out where the the location is by doing "rpm -ql <java package name>" which will list all the files in the RPM.

Looks like I can do this with the alternatives command, are there any other ways to do this?
