This chapter includes the following sections:
This document is a resource for software developers who develop Web applications and components such as HTTP servlets and JavaServer Pages (JSPs) for deployment on WebLogic Server. This document is also a resource for Web application users and deployers. It also contains information that is useful for business analysts and system architects who are evaluating WebLogic Server or considering the use of WebLogic Server Web applications for a particular application.
The topics in this document are relevant during the design and development phases of a software project. The document also includes topics that are useful in solving application problems that are discovered during test and pre-production phases of a project.
This document does not address production phase administration, monitoring, or performance tuning topics. For links to WebLogic Server documentation and resources for these topics, see Related Documentation.
It is assumed that the reader is familiar with Java EE and Web application concepts. This document emphasizes the value-added features provided by WebLogic Server Web applications and key information about how to use WebLogic Server features and facilities to get a Web application up and running.
This chapter, Chapter 1, "Introduction and Roadmap," introduces the organization of this guide.
Chapter 2, "Understanding Web Applications, Servlets, and JSPs," provides an overview of WebLogic Server Web applications, servlets, and Java Server Pages (JSPs).
Chapter 3, "Creating and Configuring Web Applications," describes how to create and configure Web application resources.
Chapter 4, "Creating and Configuring Servlets," describes how to create and configure servlets.
Chapter 5, "Creating and Configuring JSPs," describes how to create and configure JSPs.
Chapter 6, "Configuring JSF and JSTL Libraries," describes how to configure JavaServer Faces (JSF) and the JSP Tag Standard Library (JSTL).
Chapter 7, "Configuring Resources in a Web Application," describes how to configure Web application resources.
Chapter 8, "WebLogic Annotation for Web Components," describes how to simplify development by using annotations and resource injection with Web components.
Chapter 9, "Servlet Programming Tasks," describes how to write HTTP servlets in a WebLogic Server environment.
Chapter 10, "Using Sessions and Session Persistence," describes how to set up sessions and session persistence.
Chapter 11, "Application Events and Event Listener Classes," discusses application events and event listener classes.
Chapter 12, "Using the HTTP Publish-Subscribe Server," provides an overview of the HTTP Publish-Subscribe server and information on how you can use it in your Web applications
Chapter 13, "WebLogic JSP Reference," provides reference information for writing JavaServer Pages (JSPs).
Chapter 14, "Filters," provides information about using filters in a Web application.
Chapter 15, "Using WebLogic JSP Form Validation Tags," describes how to use WebLogic JSP form validation tags.
Chapter 16, "Using Custom WebLogic JSP Tags (cache, process, repeat)," describes the use of three custom JSP tags—
process—provided with the WebLogic Server distribution.
Chapter 17, "Using the WebLogic EJB to JSP Integration Tool," describes how to use the WebLogic EJB-to-JSP integration tool to create JSP tag libraries that you can use to invoke EJBs in a JavaServer Page (JSP). This document assumes at least some familiarity with both EJB and JSP.
Appendix A, "web.xml Deployment Descriptor Elements," describes the deployment descriptor elements defined in the
web.xml schema under the root element
Appendix B, "weblogic.xml Deployment Descriptor Elements," provides a complete reference for the schema for the WebLogic Server-specific deployment descriptor
Appendix C, "Support for GlassFish Deployment Descriptors," provides a list of the GlassFish deployment descriptors that are supported in WebLogic Server.
Appendix D, "Web Application Best Practices," contains Oracle best practices for designing, developing, and deploying WebLogic Server Web applications and application resources.
This document contains Web application-specific design and development information.
For comprehensive guidelines for developing, deploying, and monitoring WebLogic Server applications, see the following documents:
Developing Applications for Oracle WebLogic Server is a guide to developing WebLogic Server applications.
Deploying Applications to Oracle WebLogic Server is the primary source of information about deploying WebLogic Server applications.
Upgrade Guide for Oracle WebLogic Server contains information about Web applications, JSP, and servlet compatibility with previous WebLogic Server releases.

In addition to this document, Oracle provides examples for software developers within the context of the Avitek Medical Records Application (MedRec) sample, discussed in the next section.
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 (select Server Examples in the custom installation) with 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 Server.
WebLogic Server optionally installs API code examples in
WL_HOME is the top-level directory of your WebLogic Server installation. Select Server Examples in the custom installation. You can start the Examples Server, and obtain information about the samples and how to run them from the WebLogic Server Start menu.
Oracle provides several Web application, servlet, and JSP examples with this release of WebLogic Server. Oracle recommends that you run these Web application examples before developing your own Web applications.
This release of WebLogic Server supports a subset of GlassFish deployment descriptors so that basic Web applications which deploy and run on GlassFish Server can be deployed on WebLogic Server. For more information and to see the list of supported deployment descriptors, see Appendix C, "Support for GlassFish Deployment Descriptors."
