The prefs tool doesn't change symbolic links. It simply affects GUI tools launched either as applets or by double clicking a jar. Rather than messing with your symlinks, just point your start scripts for command line tools that need 1.4.2 to the explicit 1.4.2 install at / System/Library/Frameworks/JavaVM.framework/Versions/1.4.2/Commands/ java instead or /usr/bin/java. However, even with 1.5 installed on Tiger Server, WebObjects apps start under the 1.4.2 VM, so you shouldn't really need to do anything.

Hi Joe,

That was the first thing I did ..... and I even restarted afterward and the symbolic links all stayed the same, plus java -version still showed 1.5! So, I had my doubts after that and asked the list about the symbolic links.

Thanks for helping Joe.

Regards, Kieran

The best way to do this is to run the Java Preferences application in
/Applications/Utilities/Java/J2SE 5.0

You select there the system default JVM (between 1.4.2 or 1.5)

Hi, I'm setting up a clean install of OS X Tiger and I want to switch
to 1.4.2 VM as the default for the OS (and hence my deployed woa's).


I guess I just change the symbolic link for CurrentJDK to point to
1.4.2, .... but what is the Current -> A directory??
