Even though the NetWare graphical interface (called Console 1) looks like X Window, it is a Java-based approximation, not the real thing. You can’t run X Window programs on a NetWare server. You can, however, run programs written in Java.

Java, Anyone?


Java is a programming language similar to BASIC, Pascal, COBOL, C+, and C++, but with one major distinguishing feature: Programs written in Java run on any platform that has a Java Virtual Machine (JVM) installed.


JVM is software that creates a virtual Java computer. Most (if not all) operating systems have a JVM. This means that a programmer writes a program once, without having to recompile or rewrite the same program for all platforms. One of Java’s slogans is «Write Once, Run Anywhere.» Java was developed by Sun Microsystems and is beginning to be widely used on corporate networks.


The reason Java should be important to you is that Java programs are being used more and more. Although programs written in Java can be written once and run anywhere, they do run more slowly than their non-Java counterparts. You can usually tell you are running a Java program because a little «coffee cup» icon will appear in the upper-left corner of the window in which the program is running.


Scalable Hardware Requirements


In the days of NetWare 3.x, you could run NetWare on a server that had as little as 4MB of RAM; other network operating systems of the time required a minimum of 24MB. This made NetWare popular among hardware buyers, but not with those who made the hardware.
