update java to version 6 update 24?

I am very new to linux so I am very clumsy here…

I want to update java from version 6 update 20 to version 6 update 24. I went through the steps on

How do I download and install Java for my Linux computer?

where I installed java in home>Java>jre1.6.0_24

but I also have version 20 installed I think as default when I installed openSUSE 11.4.

The reason I am trying to update is I cannot use this online chess against the computer java app:

Play Chess Against the Computer - Chess.com

but other online java apps work through firefox that I have tried…

please tell me what I need to do here—thanks!
