Overview
The HP-UX Software Development Kit for the Java™ 2 Platform Version 1.4.2.28 release
provides the tools for developing and deploying Java applications on HP-UX 11i v1
(11.11), 11i v2 (11.23), 11i v3 (11.31) HP9000 PA-RISC, and HP-UX 11i v2 (11.23) and
11i v3 (11.31) HP Integrity systems. See HP-UX PA-RISC System Requirements (page 10)
and HP-UX HP Integrity System Requirements (page 10) for HP-UX releases that are
not supported.
Release notes are no longer included in the software kit, and instead, this online version
is your source of information for the release. It has the most up-to-date information,
especially regarding known defects, so you may want to check it occasionally for
updates. Information about the Runtime Plug-in and Java Web Start are also included
in these release notes.
There are two principal products in the Java 2 Platform Standard Edition family::
• J2SE Runtime Environment (RTE)
The RTE provides the libraries, HotSpot Java virtual machine, and other
components necessary for you to execute a Java application. You may include the
runtime environment with your Java applications as long as you adhere to the HP
software license agreement and supplemental restrictions provided in the LICENSE
file. The RTE is provided as a separate product, and it is also included in the SDK
download package. Java WebStart technology is also included in the RTE. The
Java Runtime Plug-in for Mozilla is a separate download.
• J2SE Development Kit (SDK)
The SDK is a superset of the RTE, and includes additional tools such as compilers
and debuggers that are necessary for developing applets and applications. The
SDK download package includes the RTE.
