NonStop Server for Java Programmer's Reference (NSJ 4.2+)

Installation Changes
The standard location for the NonStop Server for Java 4 is a location of the form:
/usr/tandem/nssjava/jdk142_v20
where jdk142 refers to the version number of the Sun Microsystems update upon which
NonStop Server for Java 4 is based. The number v20 identifies the particular NonStop Server
for Java 4 PVU.
When the PAX file is extracted, a symbolic link is created at the standard location:
/usr/tandem/java.
If you want to install NonStop Server for Java 4 in a nonstandard location, you can do so as
with earlier releases. To do that kind of installation, use the File Transfer Protocol (FTP) to
transfer the file from the CD to the NonStop Kernel system. Then follow the directions in the
product Softdoc for a nonstandard installation.
HP recommends that NonStop Server for Java 4 be installed in the standard
location whenever possible.

For users of NonStop Server for Java 3.1.x or earlier versions, guidelines have changed for
placing Java Archive files (JAR or .jar) for both Java based products and user-provided JAR
files.
For Java Based Products
Before version 1 of the NonStop Server for Java 4, no guidelines were provided for where Java
based products should install their JAR files. Many of these products installed their JAR files in
the /usr/tandem/java/jre/lib/ext directory. Occasionally, the installation of a Java
based product would overwrite a JAR file required by another Java based product, possibly
causing a version mismatch.
In addition, Java based products had to be reinstalled whenever NonStop Server for Java issued
a new product version.
For these reasons, beginning with version 1 of the NonStop Server for Java 4, HP 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
