This document introduces and explains the Oracle implementation of Java servlet technology, specified by an industry consortium led by Sun Microsystems. It summarizes standard features and covers Oracle implementation details and value-added features. The discussion includes basic servlets, data-access servlets, and servlet filters and event listeners.

Servlet technology is a component of the standard Java 2 Enterprise Edition (J2EE). The J2EE component of the Oracle Application Server is known as the Oracle Application Server Containers for J2EE (OC4J).

The OC4J servlet container in Oracle Application Server 10g Release 2 (10.1.2) is a complete implementation of the Sun Microsystems Java Servlet Specification, Version 2.3.

This preface contains the following sections:


The guide is intended for J2EE developers who are writing Web applications that use servlets and possibly JavaServer Pages (JSP). It provides the basic information you will need regarding the OC4J servlet container. It does not attempt to teach servlet programming in general, nor does it document the Java Servlet API in detail.

You should be familiar with the current version of the Java Servlet Specification, produced by Sun Microsystems. This is especially true if you are developing a distributable Web application, in which sessions can be replicated to servers running under more than one Java virtual machine (JVM).

If you are developing applications that primarily use JavaServer Pages, refer to the Oracle Application Server Containers for J2EE Support for JavaServer Pages Developer's Guide.

Documentation Accessibility

Our goal is to make Oracle products, services, and supporting documentation accessible, with good usability, to the disabled community. To that end, our documentation includes features that make information available to users of assistive technology. This documentation is available in HTML format, and contains markup to facilitate access by the disabled community. Accessibility standards will continue to evolve over time, and Oracle is actively engaged with other market-leading technology vendors to address technical obstacles so that our documentation can be accessible to all of our customers.
