Netscape Navigator/Communicator does not currently support Java 1.1. For best results, use Internet Explorer 4.0 with Apple's MRJ 2.0. After you have installed Internet Explorer and MRJ 2.0, set the JAVA preferences in Internet Explorer to use Apple MRJ.
Windows 95/98/NT and UNIX users
If you are using Navigator/Communicator please visit the Netscape Communicator 4.0 Download Central for JDK 1.1.
