EE5 Deployment

EE5 --Servlet2.5 ---EE5_Containers

Deployment Descriptor Elements:The following additional elements exist in the Web application deployment descriptor to meet the requirements of Web containers that are JSP pages enabled or part of a Java EE application server. They are not required to be supported by containers wishing to support only the servlet specification:

  • jsp-config
  • Syntax for looking up JNDI objects (env-entry, ejb-ref, ejb-local-ref, resource-ref, resource-env-ref)
  • Syntax for specifying the message destination (message-destination, message-destination-ref)
  • Reference to a Web service (service-ref)

Packaging and Deployment of JAX-WS Components:Web containers may choose to support running components written to implement a
Web service endpoint as defined by the JAX-RPC and/or JAX-WS specifications. Web containers embedded in a JavaEE conformant implementation are required to support JAX-RPC and JAX-WS web service components. This section describes the packaging and deployment model for such JAX-RPC and JAX-WS Web component implementations.

Rules for Processing the Deployment Descriptor:The containers and tools that are part of Java EE technology-compliant implementation are required to validate the deployment descriptor against the XML schema for structural correctness. The validation is recommended, but not required for the web containers and tools that are not part of a Java EE technology compliant implementation.
