Document Scope and Audience
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 J2EE 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.
Guide To This Document
- This chapter, Introduction and Roadmap, introduces the organization of this guide.
- Understanding Web Applications, Servlets, and JSPs, provides an overview of WebLogic Server Web applications, servlets, and Java Server Pages (JSPs).
- Creating and Configuring Web Applications, describes how to create and configure Web application resources.
- Creating and Configuring Servlets, describes how to create and configure servlets.
- Creating and Configuring JSPs, describes how to create and configure JSPs.
- Configuring JSF and JSTL Libraries, describes how to configure JavaServer Faces (JSF) and the JSP Tag Standard Library (JSTL).
- Configuring Resources in a Web Application, describes how to configure Web application resources.
- WebLogic Annotation for Web Components, describes how to simplify development by using annotations and resource injection with Web components.
- Servlet Programming Tasks, describes how to write HTTP servlets in a WebLogic Server environment.
- Using Sessions and Session Persistence, describes how to set up sessions and session persistence.
- Application Events and Event Listener Classes, discusses application events and event listener classes.
- 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
- WebLogic JSP Reference, provides reference information for writing JavaServer Pages (JSPs).
- Filters, provides information about using filters in a Web application.
- Using WebLogic JSP Form Validation Tags, describes how to use WebLogic JSP form validation tags.
- Using Custom WebLogic JSP Tags (cache, process, repeat), describes the use of three custom JSP tags—cache, repeat, and process—provided with the WebLogic Server distribution.
- 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.
- web.xml Deployment Descriptor Elements, describes the deployment descriptor elements defined in the web.xml schema under the root element <web-app>.
- weblogic.xml Deployment Descriptor Elements, provides a complete reference for the schema for the WebLogic Server-specific deployment descriptor weblogic.xml.
- Web Application Best Practices, contains Oracle best practices for designing, developing, and deploying WebLogic Web applications and application resources.

Examples for the Web Application Developer
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.
Avitek Medical Records Application (MedRec)
MedRec is an end-to-end sample J2EE 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 J2EE features, and highlights Oracle-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 Server.
Web Application 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.
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.
New and Changed Features In This Release
