The EJB 2.1 architecture specifies how a bean developer can have the bean reference a Web service through a declaration in the bean's deployment descriptor. The deployer can then link the bean to a Web service installation. This implies that the Web service to be accessed is known at development time. However, the network endpoint (the host name and TCP/IP port number) may be provided by the deployer when deployment occurs. This mechanism is similar to the ejb-ref mechanism by which an enterprise bean can declare a reference to other enterprise beans.
For referencing Web services, the enterprise bean declares a service-ref element in its deployment descriptor. The service-ref element indicates the JNDI name—in the java:comp/env namespace—at which the lookup of the Web service endpoint is performed along with the expected Java type of the service interface for the Web service. This service interface has methods to return the proxy, or stub, object for each port type in the Web service. The proxy object implements the Java service endpoint interface to which the port type has been mapped. The Java service endpoint interface contains the methods for each operation in the port type. The EJB component can invoke these methods on the proxy object to send a request to the Web service.
The service-ref element also contains the location of the WSDL file from which the service interface was created and the location of the JAX-RPC mapping file. This mapping, which is itself an XML document, provides details of how the Java service interface was generated from the WSDL. Its format is the same as the mapping file provided by a stateful session bean that implements a Web service endpoint.
