My apologies for what will be my obvious ignorance. I am only a very new coder and have almost no experience with java itself.
In fact, my problem at the moment is trying to id and fix what seems to be a bad address when I try to use Release 9 to update J2SE 1.4.2 and J2SE 5.0. on a PPC G5 running 10.4.11. J2SE 1.4.2 and J2SE 5.0 show up in Java Prefs. When I use terminal java -version, it returns:
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_05-83)
Java HotSpot(TM) Client VM (build 1.5.0_05-48, mixed mode, sharing)
So I would think that the Release 9 installer would execute. But when I launch the installer pkg, I get the message to run Software Update and all previous updates for java. Since I am running the last version of Tiger, I tried to install all previous releases of Java updates, from Release 6 - 8, but I get the same message to use Software Update and install previous Java versions.
I am going through this because a jar that tried to launch would fail and thus an app dependent on the jar executing would not launch.
In looking at one set of log info, a "bad address" message appeared. Below is the top line summary. I have the entire thread, but I haven't included it here because it is so long. Glad to do so if it would help someone steer me to the solution.
