Installed Java 1.4.1 and now my video conferencing software won't work. Anyone know how to revert back to version 1.3.1?
Thanks

1.3.1 is still installed. It's just not "Current" anymore.
Just go to:
/System/Library/Frameworks/JavaVM.framework/Versions
and change the CurrentJDK symlink to point to "1.3.1"

This should switch the default VM to 1.3.1 :
sudo -s
cd /System/Library/Frameworks/JavaVM.framework/Versions
rm CurrentJDK
ln -s 1.3.1 CurrentJDK
edit : Arkham_c, you've been faster than me

This doesn't seem to work.
sudo -s
cd /System/Library/Frameworks/JavaVM.framework/Versions
rm CurrentJDK
ln -s 1.3.1 CurrentJDK
How do I change the symlink?
Thanks

did you enter your password after sudo -s ?
try this and post the result (just to see if the link has been changed) :
ls -l /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK

This is what I get;
[Bob-Woods-Computer:~] bob% ls -l /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK
lrwxr-xr-x 1 bob wheel 5 Mar 11 16:58 /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK -> 1.3.1

It looks correct. What is this video conferencing app? how do you launch it? Terminal ? Finder? Is this a application or just a jar file?

ISPQ is the software, just launches like any other app. The app launches ok, but can't connect to anyone. The only thing that's changed is Java.

Did you restart after changing the SymLink? I would think that you shouldn't need to, but the computer wanted to be restarted after installing 1.4.1 in the first place, so it could be the same in reverse.

iSPQ does not use Java. I've tested it with 1.4.1 installed and it works on my iBook. You should switch back to 1.4.1 (as it's not the culprit).
