Preface

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.

Audience

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.

Access to Oracle Support

Oracle customers that have purchased support have access to electronic support through My Oracle Support. For information, visit http://www.oracle.com/pls/topic/lookup?ctx=acc&id=info or visit http://www.oracle.com/pls/topic/lookup?ctx=acc&id=trs if you are hearing impaired.

Diversity and Inclusion

Oracle is fully committed to diversity and inclusion. Oracle respects and values having a diverse workforce that increases thought leadership and innovation. As part of our initiative to build a more inclusive culture that positively impacts our employees, customers, and partners, we are working to remove insensitive terms from our products and documentation. We are also mindful of the necessity to maintain compatibility with our customers' existing technologies and the need to ensure continuity of service as Oracle's offerings and industry standards evolve. Because of these technical constraints, our effort to remove insensitive terms is ongoing and will take time and external cooperation.

Samples and Tutorials

In addition to this document, Oracle 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.

Oracle 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 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 about the WebLogic Server samples, see Sample Applications and Code Examples in Understanding Oracle WebLogic Server.

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 the ORACLE_HOME\wlserver\samples\server\examples\src\examples directory, where ORACLE_HOME represents the directory in which you installed WebLogic Server. For more information about the WebLogic Server code examples, see Sample Applications and Code Examples in Understanding Oracle WebLogic Server.

New and Changed WebLogic Server Features

This section includes new and changed features for recent patch sets of WebLogic Server:

New WebLogic RMI annotations that provide remote access to plain java objects. See Using WebLogic RMI Annotations.
A new connection attribute, WLContext.CONNECT_TIMEOUT, to define the length of time a client waits for connections to the server to be bootstrapped or re-established. WLContext.REQUEST_TIMEOUT is deprecated. See Using a Connect Timeout.
A new connection attribute, WLContext.RESPONSE_READ_TIMEOUT, to define the length of time that a client waits to receive a response from a server. WLContext.RMI_TIMEOUT is deprecated. See Using a Read Timeout.

For a comprehensive listing of the new WebLogic Server features introduced in this release, see What's New in Oracle WebLogic Server.
