Questions: 

I understand that Netscape 3.0 beta with Java is 
available. My question is, when will the Java Virtual Machine be available to run Java server applets or 
is this available as part of Netscape Navigator for OpenVMS.

	The only Java that is currently available on the OpenVMS platform is the version that is embedded in the latest beta version of the Netscape Navigator for OpenVMS Alpha. This is based on Sun's 1.0.2 Java. You can download this version of the Navigator from the OpenVMS web site at www.openvms.digital.com. We have just started porting Java 1.1 to OpenVMS Alpha, but its going to be 2-3 months before you're likely to see betas available. This will be the complete JDK including compiler, run time, class libraries, debugger, applet viewer, etc., and will independent of any browser. At this point we do not know if we are ever going to be able to get Java running on the VAX architecture. Java assumes IEEE floating point number format is available in the hardware, and unfortunately the VAX architecture does not provide this. We will be doing our best to try and find a solution to this problem, but please bear in mind the following: (a) if a solution is found it will involve performing floating point format translations; this will make the VAX implementation even slower than one would expect, and (b) it may turn out that it just can't be done without native IEEE floating point support from the hardware.
