Creating a Service Object

The javax.xml.ws.Service class represents the wsdl:service element which contains the definition of all of the endpoints that expose a service. As such, it provides methods that allow you to get endpoints, defined by wsdl:port elements, that are proxies for making remote invocations on a service.

[Note]Note

The Service class provides the abstractions that allow the client code to work with Java types as opposed to working with XML documents.

The Service class has two static create() methods that can be used to create a new Service object. As shown in Example 2.1, both of the create() methods take the QName of the wsdl:service element the Service object will represent, and one takes a URI specifying the location of the WSDL contract.

[Tip]Tip

All services publish their WSDL contracts. For SOAP/HTTP services the URI is usually the URI for the service appended with ?wsdl.


The value of the serviceName parameter is a QName. The value of its namespace part is the target namespace of the service. The service's target namespace is specified in the targetNamespace property of the @WebService annotation. The value of the QName's local part is the value of wsdl:service element's name attribute. You can determine this value in one of the following ways:

  1. It is specified in the serviceName property of the @WebService annotation.

  2. You append Service to the value of the name property of the @WebService annotation.

  3. You append Service to the name of the SEI.

Example 2.2 shows code for creating a Service object for the SEI shown in Example 1.7.


The code in Example 2.2 does the following:

1

Builds the QName for the service using the targetNamespace property and the name property of the @WebService annotation.

2

Calls the single parameter create() method to create a new Service object.

[Note]Note

Using the single parameter create() frees you from having any dependencies on accessing a WSDL contract.
