I'm not sure Java 1.5 is in the 9.2 update but it is on the Suse 9.3 ftp site.

Just add the 9.3 ftp area as an install source and then select Java 1.5 from there using install software in Yast.
Yast should do all the hard work for you.

Failing that download the RPMs from the Suse site and then use Yast to install them.

xgm: what did you type at the konsole?

As I told you, just download the latest version and follow the instruction for the "RPM self-extractin file.

First, as root, go to /usr and "md java".
Once there, copy the java file to this directory. The instructions don't deem it necessary, but I feel more comfortable having the culprit at hand, should the need arise.
Then you will have the correct file in /java. Just install it according to instructions.
Go to /home/<your name>/mozilla/plugins, or wherever do you have firefox, and create the symbolic link.
As I told you, don'forget the ".._02..", and the <space> dot at the end of the line
Make an "ls" to verify that the link is there, all blue!
And that's it.
Good luck!
