Java 1.3.1 on new OSX versions

I read a lot of post about change current JVM, from 1.4.1 to 1.3.1, now I can do this, but I need more.

The problem is I did all OSX upgrade from 10.2 up to 10.2.8 so now I have 1.3.1 and 1.4.1, when I try to re-install 1.3.1 I'm not able to do it because the system says I don't need it.

My questions are:

1) is there a method to completely remove 1.3.1?
2) can I install 1.3.1 if I'd installed just 1.4.1 and never before 1.3.1?
 
Hmmm... no, not really. Which procedures aren't supported in 1.4.2 anymore that you're using? Perhaps there's a comparable procedure, or a simple fix...
 
In Terminal, this will show what vesion is running;

ls -l /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK

If you have both versions installed, 1.3.1 and 1.4.1, then this should get 1.3.1 running instead of 1.4.1;

cd /System/Library/Frameworks/JavaVM.framework/Versions
rm CurrentJDK
ln -s 1.3.1 CurrentJDK


To go back to 1.4.1 -

cd /System/Library/Frameworks/JavaVM.framework/Versions
rm CurrentJDK
ln -s 1.4.1 CurrentJDK
 
thank you bobw for answer but I already read it.

Maybe I can change my question.

Suppose that I have a MAC OSX wich have installed just 1.4.1, Can I install Java131Update1?

I ask this because I have 131 and 141 if I rename 131, or move to another folder and after try to install 131, the install package tell me that I don't need to install it because my java is updated!

I want to know if it minds that I have already the 131 or it refers to 141!!!!

thank you
 
I don't know, but if you have 1.3.1 running rather than 1.4.1, then take the Java 1.4.1 out of the Receipts folder in the Library and try updating.
