For Java based products

In addition, Java based products had to be reinstalled whenever NSJ issued a new product version. Therefore, starting with first version of NSJ4, HPE recommends that the JAR files associated with Java based products remain in a product-specific directory.

When you follow this recommendation, you must include the JAR files of the Java based product in either your CLASSPATH environment variable setting, or the -classpath (-cp) command-line argument.
