[[WS-Addressing]]
= WS-Addressing

JBoss Web Services inherits full WS-Addressing capabilities from the
underlying Apache CXF implementation. Apache CXF provides support for
2004-08 and http://www.w3.org/TR/ws-addr-core/[1.0] versions of
WS-Addressing.

[[enabling-ws-addressing]]
== Enabling WS-Addressing

WS-Addressing can be turned on in multiple standard ways:

* consuming a WSDL contract that specifies a WS-Addressing assertion /
policy
* using the `@javax.xml.ws.soap.Addressing` annotation
* using the `javax.xml.ws.soap.AddressingFeature` feature

[IMPORTANT]

The supported addressing policy elements are:

....
[http://www.w3.org/2005/02/addressing/wsdl]UsingAddressing
[http://schemas.xmlsoap.org/ws/2004/08/addressing/policy]UsingAddressing
[http://www.w3.org/2006/05/addressing/wsdl]UsingAddressing
[http://www.w3.org/2007/05/addressing/metadata]Addressing
....

Alternatively, Apache CXF proprietary ways are also available:

* specifying the  _[http://cxf.apache.org/ws/addressing]addressing_
feature for a given client/endpoint
* using the `org.apache.cxf.ws.addressing.WSAddressingFeature` feature
through the API
* manually configuring the Apache CXF addressing interceptors (
`org.apache.cxf.ws.addressing.MAPAggregator` and
`org.apache.cxf.ws.addressing.soap.MAPCodec`)
* setting the _org.apache.cxf.ws.addressing.using_ property in the
message context

Please refer to the the Apache CXF documentation for further information
on the proprietary
http://cxf.apache.org/docs/ws-addressing.html[WS-Addressing setup] and
http://cxf.apache.org/docs/wsaconfiguration.html[configuration details].

[[ws-addressing-policy]]
== WS-Addressing Policy

The WS-Addressing support is also perfectly integrated with the Apache
CXF WS-Policy engine.

This basically means that the WSDL contract generation for code-first
endpoint deployment is policy-aware: users can annotate endpoints with
the `@` `javax.xml.ws.soap.` `Addressing` annotation and expect the
published WSDL contract to contain proper WS-Addressing policy (assuming
no `wsdlLocation` is specified in the endpoint's `@WebService`
annotation).

Similarly, on client side users do not need to manually specify the
`javax.xml.ws.soap.AddressingFeature` feature, as the policy engine is
able to properly process the WS-Addressing policy in the consumed WSDL
and turn on addressing as requested.

[[example]]
== Example

Here is an example showing how to simply enable WS-Addressing through
WS-Policy.

[[endpoint]]
=== Endpoint

A simple JAX-WS endpoint is prepared using a java-first approach;
WS-Addressing is enforced through `@Addressing` annotation and no
`wsdlLocation` is provided in `@WebService`:

[source, java]
----
package org.jboss.test.ws.jaxws.samples.wsa;
 
import javax.jws.WebService;
import javax.xml.ws.soap.Addressing;
import org.jboss.logging.Logger;
 
@WebService
(
   portName = "AddressingServicePort",
   serviceName = "AddressingService",
   targetNamespace = "http://www.jboss.org/jbossws/ws-extensions/wsaddressing",
   endpointInterface = "org.jboss.test.ws.jaxws.samples.wsa.ServiceIface"
)
@Addressing(enabled=true, required=true)
public class ServiceImpl implements ServiceIface
{
   private Logger log = Logger.getLogger(this.getClass());
 
   public String sayHello(String name)
   {
      return "Hello " + name + "!";
   }
}
----

The WSDL contract that's generated at deploy time and published looks
like this:

[source, xml]
----
<wsdl:definitions ....>
...
  <wsdl:binding name="AddressingServiceSoapBinding" type="tns:ServiceIface">
    <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
    <wsaw:UsingAddressing wsdl:required="true"/>
    <wsp:PolicyReference URI="#AddressingServiceSoapBinding_WSAM_Addressing_Policy"/>
 
    <wsdl:operation name="sayHello">
      <soap:operation soapAction="" style="document"/>
      <wsdl:input name="sayHello">
        <soap:body use="literal"/>
      </wsdl:input>
      <wsdl:output name="sayHelloResponse">
        <soap:body use="literal"/>
      </wsdl:output>
    </wsdl:operation>
 
  </wsdl:binding>
  <wsdl:service name="AddressingService">
    <wsdl:port binding="tns:AddressingServiceSoapBinding" name="AddressingServicePort">
      <soap:address location="http://localhost:8080/jaxws-samples-wsa"/>
    </wsdl:port>
  </wsdl:service>
    <wsp:Policy wsu:Id="AddressingServiceSoapBinding_WSAM_Addressing_Policy"
       xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
      <wsam:Addressing xmlns:wsam="http://www.w3.org/2007/05/addressing/metadata">
        <wsp:Policy/>
      </wsam:Addressing>
    </wsp:Policy>
</wsdl:definitions>
----

[[client]]
=== Client

Since the WS-Policy engine is on by default, the client side code is
basically a pure JAX-WS client app:

[source, java]
----
QName serviceName = new QName("http://www.jboss.org/jbossws/ws-extensions/wsaddressing", "AddressingService");
URL wsdlURL = new URL("http://localhost:8080/jaxws-samples-wsa?wsdl");
Service service = Service.create(wsdlURL, serviceName);
ServiceIface proxy = (ServiceIface)service.getPort(ServiceIface.class);
proxy.sayHello("World");
