what I did ; instead of using the rpm.bin, I used the Linux.tgz file and got it working, hopefully you will find this info helpful, also you should check the sticky thread in this forum about the java install, because there are a couple of things you need to do after you get it installed.
One more thing, I didn't use 1.4.2, I used the JDK5.0 you can find it here;
http://java.sun.com/j2se/1.5.0/download.jsp
Again I hope you find this info. helpful
Yours Trully,
