1 Introduction
Unless stated otherwise, the information in this Programmer's Guide applies to HP-UX,
PA-RISC, and HP-UX Itanium® Processor Family systems.
Java™, the programming language, creates a new paradigm of platform independence,
meaning that Java™ applications, once written, can be executed on any computer
system.
The HP-UX Programmer's Guide for Java™ 2 provides information on how to use the
HP-UX JDK and the HP-UX Java™ Runtime Environment for the Java™ 2 Platform to
develop or deploy performance-enhanced Java™ applications on HP servers series
rp5400, rp7400, rp8400, and superdome, and PA-RISC and Itanium based workstations.
It contains information on HotSpot options, HP-specific options and features,
suggestions and examples for allocating memory, how to use wdb to examine backtraces
in Java threads, code examples for using Java Native Interface, and more.
This guide supplements other HP-UX Java™ Documentation and industry-standard
Java™ documentation, such as the following:
• The Java™ Series books published by Addison-Wesley
• "Java™ in a Nutshell (fourth edition)" by David Flanagan
• “Sam's Teach Yourself Java™ 2 in 21 Days, Professional Reference Edition (3rd
