Next, the details of the port are specified. The Web service deployment

descriptor, called 

webservices.xml

, defines and declares the structural details for

the port of a Web service. This file contains the following information:

  A logical name for the port that is also unique among all port components 

(

port component name

 element)

  The service endpoint interface for the port (

service endpoint interface

element)

  The name of the class that implements the service interface 

(

service impl bean

 element)

  The WSDL file for the service (

wsdl file

 element)

  A 

QName

 for the port 

(wsdl port

 element)

  A correlation between WSDL definitions and actual Java interfaces and defi 

nitions using the mapping file (

jaxrpc mapping file

 element)

  Optional details on any handlers

The reference to the service implementation bean, specified using the

service impl bean

 element in 

webservices.xml

, is either a 

servlet link

 or an

ejb link

 depending on whether the endpoint is a JAX RPC or EJB service end
