1 Introduction and Roadmap

This chapter describes the contents and organization of this guide—Developing JTA Applications for Oracle WebLogic Server.

This chapter includes the following sections:

1.1 Document Scope and Audience

This document is written for application developers who are interested in building transactional Java applications that run in the WebLogic Server environment. It is assumed that readers are familiar with the WebLogic Server platform, Java Platform, Enterprise Edition (Java EE) programming, and transaction processing concepts.

1.2 Guide to this Document

1.3 Related Documentation

This document contains JTA-specific design and development information. For comprehensive guidelines for developing, deploying, and monitoring WebLogic Server applications, see the following documents:

1.4 Samples and Tutorials

In addition to this document, Oracle optionally provides a variety of code samples and tutorials for developing transactional applications. The examples and tutorials illustrate WebLogic Server in action, and provide practical instructions on how to perform key application development tasks. You can start the Examples server from the ORACLE_HOME\user_projects\domains\wl_server directory, where ORACLE_HOME is the directory you specified as Oracle Home when you installed Oracle WebLogic Server. See Sample Applications and Code Examples in Understanding Oracle WebLogic Server.

1.4.1 Avitek Medical Records Application (MedRec) and Tutorials

MedRec is an end-to-end sample Java EE application shipped with WebLogic Server that simulates an independent, centralized medical record management system. The MedRec application provides a framework for patients, doctors, and administrators to manage patient data using a variety of different clients.

MedRec demonstrates WebLogic Server and Java EE features, and highlights Oracle-recommended best practices. MedRec is optionally installed in the WebLogic Server installation. You can start MedRec from the ORACLE_HOME\user_projects\domains\medrec directory, where ORACLE_HOME is the directory you specified as Oracle Home when you installed Oracle WebLogic Server. For more information, see Sample Applications and Code Examples in Understanding Oracle WebLogic Server.
