Updating java 1.5 on Solaris 10

Hello,
Could you, please, summarize how to ideally update the default java version ?

I have:

$ java -version
java version "1.5.0_07"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_07-b03)
Java HotSpot(TM) Server VM (build 1.5.0_07-b03, mixed mode)

But I need to update it in order to try to fulfill some requirements of sconadm for registering a machine as per ticket SR 3-4576198391.

So I was suggested to apply patch 118667-32 in order to reach jdk 5.0 update 30.

But after adding the patch, "java -version" didn't showed me the expected version.

Then I backed out the patch, removed the java packages and installed java 1.5
