Concurrency Utilities for Java EE (JSR-236) executes and manages asynchronous tasks to be processed in parallel by enabling application servers to maintain contexts.
This guide is intended for developers who want to use Concurrency Utilities for Java EE in JEUS® (hereafter JEUS).
To understand the basic usage and concepts of JEUS, refer to the following guides.
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 document only discusses JEUS. For more information about the Java EE standard, refer to relevant documents.
This guide consists of 2 chapters.
Descriptions of each are as follows:
"Chapter 1. Concurrency Utilities for Java EE"
Describes Concurrency Utilities for Java EE and JEUS.
Describes managed objects, as well as how to execute asynchronous tasks using ManagedObjects in JEUS.
