mac os-x java 1.4.1 beta 10 help

So after downloading around 500 megs of files from apple, I have finally been able to 1.4.1 install on my home machine, yeah. The problem I have been having is that it appears they have stopped developing javac (is this true?) and have been using ibm’s jikes. Now that should be fine, but jikes, when at the command line wants to know were the java/lang classes exist. Anyone know off hand where they are in a 10.2.3 distribution?.. I’m sure I’ll find them soon, but I’d be greatful for any suggestions.

thanks
