Abstract
This redbook covers many aspects of Java in relation to the OS/390 platform. It
focuses mainly on running server-side Java in the form of servlets or Java Server
Pages, and provides a technical overview of the new native code compiler for Java
on OS/390. It also explains SQLJ, which is a new technique for accessing DB2
databases.
A CD-ROM is included that provides easy-to-use sample applications.
The sample code associated with this redbook is also available in
softcopy on the Internet from the redbooks Web server.

An earlier redbook, "Integrating Java with Existing Data and Applications on OS/390",
SG24-5142, covers general topics regarding running Java on OS/390 and gives
examples of solutions that use Java applets to communicate with OS/390 back-end
systems. For the most complete understanding of how to use Java on OS/390, we
recommend that you have both redbooks and the CD-ROM on your bookshelf.
This redbook is divided into several parts:
Part 1. Overview of the Java Application Environment on OS/390
In this part we introduce you to the environment in which a Java
enterprise application is likely to be implemented. We present the most
widely used components and back-end subsystems and describe how
they can be integrated with Java.
Part 2. Configure the Java Application Environment on OS/390
In this part we describe the configuration of the most essential
components on OS/390 and explain how to configure your workstation
environment for developing your applications using VisualAge for Java
Version 2 for OS/390 and NetObjects Fusion.
Part 3. Develop Application Solutions for OS/390 using Java
In this part we show how you can build applications in Java using
existing transactions and databases. Our focus is on the usage of
servlets and JavaServer Pages to connect to DB2, IMS and CICS.
In Chapter 9, DB2 Access on page 131, we focus on a
new way of accessing DB2 from Java: SQLJ.
In Chapter 10, Developing Java Solutions for CICS on OS/390 on
page 169, we show how you can develop and test on Windows NT and
run the same application on an OS/390.
In Chapter 11, Accessing IMS Transactions from the Web on
page 223, we show how you can access IMS from a Webserver via
different methods.
Part 4. Using Servlets and JavaServer Pages on OS/390
In this part we give an overview of servlets and JavaServer Pages and
how they compare.
Part 5. Using VisualAge for Java ET/390 and HPJ/390
In this part we explain how VisualAge for Java supports the OS/390
platform with some specific features especially designed for developers
who want to use OS/390 as the runtime platform.
