For information about product changes for this version, see New and Changed Information. For users
migrating from NonStop Server for Java 3.1.x or earlier versions, also see "New and Changed
Information" in the NonStop Server for Java Programmer's Reference under NonStop Server for Java 4.0
in the NonStop Technical Library.
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 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.
Java Based JAR File Locations
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.
