Samples and Tutorials

In addition to this document, Oracle 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. Start the Examples server from the Start menu on Windows machines. For Linux and other platforms, start the Examples server from the WL_HOME\samples\domains\wl_server directory, where WL_HOME is the top-level installation directory for WebLogic Platform.

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 included in the WebLogic Server distribution, and is accessed from the Start menu on Windows machines. For Linux and other platforms, start MedRec from the WL_HOME\samples\domains\medrec directory, where WL_HOME is the top-level installation directory for WebLogic Platform.
