Document Scope and Audience
This document is a resource for developers who want to create standalone client applications that interoperate with WebLogic Server.
This document is relevant to the design and development phases of a software project. The document also includes solutions to application problems that are discovered during test and pre-production phases of a project.
It is assumed that the reader is familiar with Java Platform, Enterprise Edition (Java EE) concepts. This document emphasizes the value-added features provided by WebLogic Server and key information about how to use WebLogic Server features and facilities when developing standalone clients.

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 examples before developing your own applications.
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
\user_projects\domains\medrec directory, where
ORACLE_HOME is the directory you specified as the Oracle Home when you installed Oracle WebLogic Server. See Sample Applications and Code Examples in Understanding Oracle WebLogic Server.
MedRec includes a service tier consisting 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
\wlserver\samples\server directory. For more information about the WebLogic Server code examples, see Sample Applications and Code Examples in Understanding Oracle WebLogic Server.
