Dont use the version of Java that comes with Red Hat. Its old and incompatable with just about everything.
Here’s how to remove it:
yum remove | grep *java*
This will remove the java package and all of the dependancies. Make sure to follow the directions on setting up the Red Hat RPM CD as a yum repository first before doing this.
To make sure java is compleatly removed type
java -version
You shouldn’t get any information.
