NonStop Server for Java 5.0 Programmer's Reference
When choosing a Java tutorial or book, check that the information is appropriate for use with
the JDK 5.0 implementation. Also, books and tutorials about how to write graphical user
interfaces are not useful because the NonStop Server for Java 5 is a headless implementation.
Learning About Open System Services (OSS)
OSS is the open computing interface to the HP NonStop operating systemthe operating system
for NonStop servers. Java applications run in the OSS environment.
The user interface in the OSS environment is called the OSS "shell." The OSS shell is a
program that interprets the commands you enter, runs the programs you ask for, and sends
output to your screen. The OSS shell supports the Korn shell (sh), a shell common to UNIX
systems.
The default shell prompt is a $ (dollar sign). (This is the default prompt for the Korn shell.)
Throughout this manual, a $ is used to represent the OSS shell prompt.
Depending on your programming experience with NonStop systems or UNIX systems, use the
following sources to gain the prerequisite knowledge to run Java applications on NonStop
systems.
Open System Services User's Guide●
UNIX Tutorials●
If you are familiar with using the Korn shell, you only need to peruse the Open System Services
User's Guide (especially Section 2, OSS File System) for pertinent platform-specific
information to get started using Java in the OSS environment.
The Open System Services User's Guide
The Open System Services User's Guide describes the OSS user environment; the shell, file
system, and user commands. Topics of particular interest for beginning users follow.
Note: Although this guide is available only for G-series RVUs in the NTL Library,
H-series users should read it, too. For H-series users, the definitive discussions are
in the Open System Services Programmer's Guide.
The OSS File System
Discusses OSS files, directories, subdirectories, and pathnames. Also, describes how files
in the OSS file system relate to the Guardian file system (for those familiar with the
Guardian file system).
The OSS Shell
Discusses the features and environment of the OSS shell and how they can be used and
modified.
