Deployment Descriptor

This chapter specifies the JavaTM Servlet Specification version 2.5 requirements for Web container support of deployment descriptors. The deployment descriptor conveys the elements and configuration information of a Web application between Application Developers, Application Assemblers, and Deployers. For Java Servlets v.2.4 and greater, the deployment descriptor is defined in terms of an XML schema document. For backwards compatibility of applications written to the 2.2 version of the API, Web containers are also required to support the 2.2 version of the deployment descriptor. For backwards compatibility of applications written to the 2.3 version of the API, Web containers are also required to support the 2.3 version of the deployment descriptor. The 2.2 and 2.3 versions are defined in the appendices.
