This document is intended for users who choose JEUS to develop application clients. The document describes the concept and usage of JEUS application clients and the concept of JNLP. An application client is an executable program as follows:
Java application client
Applet
JNLP client
The source codes for examples used in the document are executable and available in the JEUS_HOME\samples\client directory.
To understand the basic usage and concepts of JEUS, refer to the following guides.
For clients using web services, additional processes that are not discussed in this guide may be required.
All examples and environment configurations are written according to the UNIX style. Hence, a few considerations must be given when working in a non-UNIX environment such as Microsoft Windows™ (hereafter Windows).
For example, for path delimiters, the UNIX style "/" must be changed to the Windows style, "\". The environment variables must also be changed to the Windows style, (%%). JEUS_HOME, referred to throughout this guide, is the directory in which JEUS is installed.
This guide does not cover Java EE or Java specifications in detail. For more information, refer to relevant Java documents.
This guide consists of 4 chapters.
Descriptions of each are as follows:
"Chapter 1. Application Clients"
Describes application clients that are executed on a separate JVM from the JEUS server.
"Chapter 2. Advanced Application Clients"
Describes advanced modules of application client.
Describes how to create, configure, and execute an applet program in JEUS.
Describes how to deploy a client and its JNLP file to the web application, and how to execute a client.
