This document is intended for JEUS® (hereafter JEUS) system administrators and developers who want to deploy J2EE Enterprise JavaBeans to the JEUS system.
This guide describes not only the concept of EJB, but also EJB engines, EJB modules, and EJB clients. To fully understand this guide, users must have knowledge of the following.
Java EE specifications
Basic concept of EJB
To understand the basic usage and concepts of JEUS, refer to the following guides.
This guide includes examples and environment settings in UNIX. To use them in other environments such as Microsoft Windows™ (hereafter Windows), users need to consider several conditions.
For example, the Unix delimiter "/" should be replaced with the Windows delimiter "\". The environment variables also need to be specified using (%%). Note that JEUS_HOME referred to in this guide is the home directory of JEUS.
This guide does cover basic technologies of EJB. Refer to other related documents. Entity Bean is replaced by JPA from EJB 3.0. For more information, refer to the JEUS JPA Guide.
This guide consists of 12 chapters and 2 appendices.
Descriptions of each are as follows:
"Chapter 1. Introduction to EJB"
Describes the components and characteristics of EJB, and how to install EJB and to configure its environment.
Describes basic knowledge of the EJB engine. It also describes the top-level concepts of JEUS EJB, such as its structure, configuration, operation, monitoring, and tuning.
Describes EJB module structure and how to manage the modules.
"Chapter 4. Common Characteristics of EJB"
Describes the common characteristics of EJBs in JEUS environment.
"Chapter 5. Interoperability and RMI-IIOP"
Describes interoperability and RMI-IIOP protocol used by EJB.
Describes the concept of EJB clustering and how to configure main functions of EJB.
Describes stateless session beans and stateful session beans in detail.
Describes everything about configuring and tuning entity beans in JEUS EJB engine.
"Chapter 9. Message Driven Beans (MDBs)"
Describes some precautions for using Message Driven Beans (MDBs) in the JEUS engine.
"Chapter 10. EJB Timer Service"
Describes explanation and setting of the timer service in JEUS EJB.
Describes an example of EJB client programming and how to configure the InitialContext object.
"Chapter 12. Additional Functions"
Describes additional functions that are used to implement EJB in JEUS.
"Appendix A. Basic Java Type and Database Field Mappings"
Describes the basic mapping between a Java field type specified by JEUS and a database column type from the main Database vendors supported by JEUS.
"Appendix B. Instant EJB QL API Reference"
Describes how to use the instant EJB QL API methods and interfaces.
