This package name and location is determined by the user. For more information, see the Java documentation. This package must be distributed with the application in a place that is on the CLASSPATH for the Java interpreter. One technique is to place it in a subdirectory from the application files, and make sure the CLASSPATH has "." in it for the local directory.

For convenience, it makes sense to write a simple bourne shell script to set these variables before calling the Java interpreter, as shown below:

#!/bin/sh
LD_LIBRARY_PATH=$(LD_LIBRARY_PATH):.;export LD_LIBRARY_PATH
CLASSPATH=$(CLASSPATH):classes.jar:.;export CLASSPATH
