To load NJVM (java.nlm), at the Server Console enter
load java
This loads NJVM into memory and allows the command interpreter to recognize when a Java application or applet is launched.
You can unload NJVM (java.nlm) from memory by entering the following command at the Server Console:
java -exit
This command is a clean unload. It lets the applications do a proper shutdown.
Or you can enter
unload java
This command sends a java -kill command on the applications.
