installing older versions of java

Hello all,

I use older versions of java with access control systems. One system that i use requires java 1.42 I was able to use the 1.5 version with os x 10.5. With snow leopard it has been upgraded to 1.6 and all other versions are gone.

How can i install older versions of java. I have tried downloading, but they all say that they can not be installed on this machine.

Thanks

Mac OS X (10.6)

Hello,

Upgraded to 10.6 today and also need older version of java install. I use this for developing on eclipse. From what i am reading it does not look like its support <6.0 . Is this correct?

I was able to get Java 1.4.2 working with Safari in Snow Leopard tonight. Here's how to do it.

1. Install Java 1.4.2 as outlined in this link:
http://wiki.oneswarm.org/index.php/OSX_10.6_SnowLeopard

Alternatively, extract Java 1.4.2 from the Java For Mac OS X 10.5 Update 4 installation package, and install it in a similar manner:
http://support.apple.com/downloads/Javafor_Mac_OS_X_10_5_Update4

2. Make sure that Java 1.4.2 is the first 32-bit application in the list. Under Java Preferences, my list reads:

Java SE 6 64-bit
J2SE 1.4.2 32-bit
Java SE 6 32-bit

3. Open Safari in 32-bit mode via the Get Info window for Safari. This is where I was getting screwed up. It finally occurred to me that Java 1.4.2 is a 32-bit application, but if Safari was opening in 64-bit mode, it wouldn't use the 32-bit Java apps.

Once I opened Safari in 32-bit mode, Safari was able to use Java 1.4.2.

I just copied 1.5.0 from my backup and deleted the symbolic link from Versions and put the 1.5.0 directory in its place. It works, but I keep getting this in my logs for my 1.5 Java programs:

\[java\] Shared archive: uninstalled generation

It makes me suspicious.

Thanks! This solved a problem I was having with MATLAB R2007a, which stopped working after I upgraded to Snow Leopard. Downgrading to Java 1.5.0 as described at http://wiki.oneswarm.org/index.php/OSX_10.6_SnowLeopard fixed me. I was getting errors after attempting certain actions involving new windows and a directory service. Now I'm back in business.
