| Oracle Application Server Containers for J2EE Servlet Developer's Guide 10g (9.0.4) Part Number B10321-01 |
|
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 (9.0.4) is a complete implementation of the Sun Microsystems Java Servlet Specification, Version 2.3.
This document also provides an overview of OC4J deployment and configuration, with detailed descriptions of key configuration files.
Because this manual is intended for developers, its content is largely targeted for users of the OC4J standalone development environment; however, there is ample consideration of OC4J within an Oracle Application Server production environment.
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).
Because this is a developer's guide, and development and testing are more convenient in an OC4J standalone environment, key aspects of OC4J standalone are discussed, and the assumption is that most developers will be using a standalone environment at some point in their development.
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.
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. Standards will continue to evolve over time, and Oracle Corporation 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.

JAWS, a Windows screen reader, may not always correctly read the code examples in this document. The conventions for writing code require that closing braces should appear on an otherwise empty line; however, JAWS may not always read a line of text that consists solely of a bracket or brace.
This documentation may contain links to Web sites of other companies or organizations that Oracle Corporation does not own or control. Oracle Corporation neither evaluates nor makes any representations regarding the accessibility of these Web sites.
This document contains:
Summarizes servlet technology and servlet development in general, introduces the OC4J servlet container, and provides a simple "Hello World" example.
Describes how the OC4J servlet container supports servlet development and invocation, including a discussion of key development considerations, a summary of servlet SSL features, and related examples. This chapter also introduces the OC4J standalone environment for the development stages.
Explains the use of filters to affect servlet input or output, and event listeners to track session and application events and manage resources accordingly. These features were introduced in the servlet 2.3 specification.
Provides examples for using JDBC calls and EJB calls from servlets.
Discusses how to build and deploy a Web application in OC4J, and provides an overview of files for servlet and Web site configuration. This chapter is primarily useful for OC4J standalone users but also considers Oracle Application Server.
Documents all the elements and attributes of the global-web-application.xml and orion-web.xml files for servlet configuration, and the default-web-site.xml file (or other Web site XML files) for Web site configuration. This level of detail is primarily useful for OC4J standalone users.
Shows and describes Oracle Enterprise Manager pages for servlet and Web site configuration for deployment to an Oracle Application Server environment.
This appendix has instructions for an OC4J standalone environment for installing and running open source framework utilities you can use with OC4J. For the OC4J 9.0.4 implementation, this consists of Struts and log4j from the Apache Jakarta Project.
This appendix includes the Third Party License for third party products included with Oracle Application Server and discussed in this document.

Additional OC4J documents available from the Oracle Java Platform Group:
This book provides some overview and general information for OC4J; primer chapters for servlets, JSP pages, and EJBs; and general configuration and deployment instructions.
This version of the user's guide is specifically for the standalone version of OC4J, and is available when you download the standalone version from OTN. OC4J standalone is used in development environments, but not typically in production environments. (Because a servlet developer will often find it useful to use OC4J standalone during development, considerations for the standalone version are discussed throughout the Oracle Application Server Containers for J2EE Servlet Developer's Guide.)
This book provides information for JSP developers who want to run their pages in OC4J. It includes a general overview of JSP standards and programming considerations, as well as discussion of Oracle value-added features and steps for getting started in the OC4J environment.
This book provides conceptual information and detailed syntax and usage information for tag libraries, JavaBeans, and other Java utilities provided with OC4J. There is also a summary of tag libraries from other Oracle product groups.
This book provides information about standards-based Java services supplied with OC4J, such as JTA, JNDI, JMS, JAAS, and the Oracle Application Server Java Object Cache.
This document (not to be confused with the Oracle Application Server 10g Security Guide), describes security features and implementations particular to OC4J. This includes information about using JAAS, the Java Authentication and Authorization Service, as well as other Java security technologies.
This book provides information about the EJB implementation and EJB container in OC4J.
