Introduction and Roadmap

This section describes the contents and organization of this guide—Programming WebLogic RMI.

Document Scope and Audience

This document is written for application developers who want to build e-commerce applications using Remote Method Invocation (RMI) and Internet Interop-Orb-Protocol (IIOP) features. It is assumed that readers know Web technologies, object-oriented programming techniques, and the Java programming language. This document emphasizes the value-added features provided by WebLogic Server® and key information about how to use WebLogic Server features when developing applications with RMI.

Guide to this Document

This document describes the BEA WebLogic Server RMI implementation of the JavaSoft^TM Remote Method Invocation (RMI) specification from Sun Microsystems. The BEA implementation is known as WebLogic RMI.

This chapter, Introduction and Roadmap, introduces the organization of this guide.
Understanding WebLogic RMI, is an overview of WebLogic RMI features and its architecture.
WebLogic RMI Features, describes the features that you use to program RMI for WebLogic Server.
Using the WebLogic RMI Compiler, provides information on the WebLogic RMI compiler.
How to Implement WebLogic RMI, provides a simple step by step example of how to implement WebLogic RMI.
Using RMI over IIOP, defines RMI over IIOP and provides general information about the WebLogic Server RMI-IIOP implementation.
Configuring WebLogic Server for RMI-IIOP, describes concepts, issues, and procedures related to using WebLogic Server to support RMI-IIOP applications.
Best Practices for Application Design, describes recommended design patterns when developing RMI and RMI over IIOP applications.
CORBA Support for WebLogic Server, provides information on CORBA support for WebLogic Server.

Samples and Tutorials

In addition to this document, BEA Systems provides a variety of code samples and tutorials for developers. The examples and tutorials illustrate WebLogic Server in action, and provide practical instructions on how to perform key development tasks.

BEA recommends that you run some or all of the RMI examples before developing your own applications.

Avitek Medical Records Application (MedRec) and Tutorials

MedRec is an end-to-end sample Java Platform, Enterprise Edition (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 BEA-recommended best practices. MedRec is included in the WebLogic Server distribution, and can be accessed from the Start menu on Windows machines. For Linux and other platforms, you can start MedRec from the WL_HOME\samples\domains\medrec directory, where WL_HOME is the top-level installation directory for WebLogic Platform.

MedRec includes a service tier comprised primarily of Enterprise Java Beans (EJBs) that work together to process requests from web applications, web services, and workflow applications, and future client applications. The application includes message-driven, stateless session, stateful session, and entity EJBs.

Examples in the WebLogic Server Distribution

WebLogic Server optionally installs API code examples in WL_HOME\samples\server\examples\src\examples, where WL_HOME is the top-level directory of your WebLogic Server installation. You can start the examples server, and obtain information about the samples and how to run them from the WebLogic Server Start menu.

Additional Examples Available for Download

Additional API examples for download at http://dev2dev.bea.com/. These examples are distributed as .zip files that you can unzip into an existing WebLogic Server samples directory structure. You build and run the downloadable examples in the same manner as you would an installed WebLogic Server example. See the download pages of individual examples for more information.

New and Changed Features in This Release
