Deploying and Packaging a Service Endpoint

  A port component (also called a port) gives a view of the service to clients such 

that the client need not worry about how the service has been implemented.

  Each port has an associated WSDL.

  Each port has an associated service endpoint (and its implementation). The 

endpoint services all requests that pass through the location defined in the 

WSDL port address.

To begin, the service implementation declares its deployment details in the

appropriate module specific deployment descriptors. For example, a service

implementation that uses a JAX RPC service endpoint declares its details in the

WEB INF/web.xml

 file using the 

servlet class

 element. (See Code Example

3.21.)

web.xml

 File for a JAX RPC Service Endpoint

Note that when you have a service that functions purely as a Web service

using JAX RPC service endpoints, some specifications in the 

web.xml

 file, such

as 

 and 

, have no effect.

A service implementation that uses an EJB service endpoint declares its

deployment details in the file 

META INF/ejb jar.xml

 using the 

session

 element.
