How to activate changes made in JRE

My system has JRE 1.5.0 update 5 installed on it.

I want to include one of the directories (\jre\lib\zi) of update 6 into my current setup of update 5.

I have changed the directory, but how do I activate it?

If I reinstall JRE update 5, it is going to remove the changes I made.

Is there a way around it?

Thanks.

1. If you change java like that you can't distribute it.

2. Making changes like that means that you are on your own as to whether it works.

3. If you get it to work this time it doesn't mean it will work next time.

4. Each time you install something that might touch it you must manually move the files in and then retest to verify not only that your change works but that the rest of the VM still works.
