Chapter 5.  Addressing Tutorial

This tutorial will show you how to create client and endpoint communication with WS-Addressing enabled. Creating a WS-Addressing based service and client is very simple. The first step is to create regular JAX-WS service and client configuration; the last step is to configure the addressing on both sides.
The Service

We will start with the following endpoint implementation. 

package org.jboss.test.ws.jaxws.samples.wsa;
        
import javax.jws.WebService;
  @WebService
(
   portName = "AddressingServicePort",
   serviceName = "AddressingService",
   targetNamespace = "http://www.jboss.org/jbossws/ws-extensions/wsaddressing",
   endpointInterface = "org.jboss.test.ws.jaxws.samples.wsa.ServiceIface"
)
public class ServiceImpl implements ServiceIface
{
   public String sayHello()
   {
      return "Hello World!";
   }
}

The above endpoint implements the following endpoint interface: 
package org.jboss.test.ws.jaxws.samples.wsa;
 
import javax.jws.WebMethod;
import javax.jws.WebService;
 
@WebService
(
   targetNamespace = "http://www.jboss.org/jbossws/ws-extensions/wsaddressing"
)
public interface ServiceIface
{
   @WebMethod
   String sayHello();
}

Let's say that compiled endpoint and interface classes are located in directory /home/username/wsa/cxf/classes. The next step is to generate the JAX-WS artifacts and WSDL that will be part of the endpoint archive.
Generating WSDL and JAX-WS Endpoint Artifacts

We will use the wsprovide commandline tool to generate WSDL and JAX-WS artifacts. Here's the command: 

 
cd JBOSS_HOME/bin
./wsprovide.sh --keep --wsdl \
   --classpath=/home/username/wsa/cxf/classes \
   --output=/home/username/wsa/cxf/wsprovide/generated/classes \
   --resource=/home/username/wsa/cxf/wsprovide/generated/wsdl \
   --source=/home/username/wsa/cxf/wsprovide/generated/src \
   org.jboss.test.ws.jaxws.samples.wsa.ServiceImpl

The above command generates the following artifacts:
Compiled classes
SayHello.class
SayHelloResponse.class
Java Sources
SayHello.java
SayHelloResponse.java
Contract Artifacts
AddressingService.wsdl
All previously mentioned generated artifacts will be part of the endpoint archive, but before we create the endpoint archive, we need to reference generated WSDL from the endpoint. We will use the wsdlLocation annotation attribute. This is the updated endpoint implementation before it is packaged to the war file: 
package org.jboss.test.ws.jaxws.samples.wsa;
 
import javax.jws.WebService;
 
@WebService
(
   portName = "AddressingServicePort",
   serviceName = "AddressingService",
   wsdlLocation = "WEB-INF/wsdl/AddressingService.wsdl",
   targetNamespace = "http://www.jboss.org/jbossws/ws-extensions/wsaddressing",
   endpointInterface = "org.jboss.test.ws.jaxws.samples.wsa.ServiceIface"
)
public class ServiceImpl implements ServiceIface
{
   public String sayHello()
   {
      return "Hello World!";
   }
}

The created endpoint war archive consists of the following entries: 
     jar -tvf jaxws-samples-wsa.war

Writing Regular JAX-WS Client

The following is the regular JAX-WS client using endpoint interface to lookup the webservice: package.org.jboss.test.ws.jaxws.samples.wsa: 

package.org.jboss.test.ws.jaxws.samples.wsa:

import java.net.URL;
import javax.xml.namespace.QName;
import javax.xml.ws.Service;

public final class SimpleServiceTestCase
{
   private final String serviceURL = "http://localhost:8080/jaxws-samples-wsa/AddressingService";
   
   public static void main(String[] args) throws Exception
   {
      // create service
      QName serviceName = new QName("http://www.jboss.org/jbossws/ws-extensions/wsaddressing", "AddressingService");
      URL wsdlURL = new URL(serviceURL + "?wsdl");
      Service service = Service.create(wsdlURL, serviceName);
      ServiceIface proxy = (ServiceIface)service.getPort(ServiceIface.class);
      
      // invoke method
      proxy.sayHello();
   }
   
}

We have both endpoint and client implementations but without WS-Addressing in place. Our next goal is to turn on the WS-Addressing feature.

5.1.  Turning on WS-Addressing 1.0
复制链接

There are two steps remaining in order to turn on WS-Addressing in JbossWS-CXF.
  • Annotate service endpoint with @Addressing annotation.
  • Modify client to configure WS-Addressing using the JAX-WS webservice feature.
Updating Endpoint Code to Configure WS-Addressing

Now we need to update endpoint implementation to configure WS-Addressing. Here's the updated endpoint code: 

 
package org.jboss.test.ws.jaxws.samples.wsa;
 
import javax.jws.WebService;
import javax.xml.ws.soap.Addressing;
 
@WebService
(
   portName = "AddressingServicePort",
   serviceName = "AddressingService",
   wsdlLocation = "WEB-INF/wsdl/AddressingService.wsdl",
   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
{
   public String sayHello()
   {
      return "Hello World!";
   }
}
Copy to Clipboard Toggle word wrap
We have added the JAX-WS 2.1 Addressing annotation to configure WS-Addressing. The next step is to repackage the endpoint archive to apply this change.
Updating Client Code to Configure WS-Addressing

We need to update client implementation to configure WS-Addressing. Here's the updated client code: 

package org.jboss.test.ws.jaxws.samples.wsa;
 
import java.net.URL;
import javax.xml.namespace.QName;
import javax.xml.ws.Service;
import javax.xml.ws.soap.AddressingFeature;
 
public final class AddressingTestCase
{
   private final String serviceURL = "http://localhost:8080/jaxws-samples-wsa/AddressingService";
   
   public static void main(String[] args) throws Exception
   {
      // construct proxy
      QName serviceName = new QName("http://www.jboss.org/jbossws/ws-extensions/wsaddressing", "AddressingService");
      URL wsdlURL = new URL(serviceURL + "?wsdl");
      Service service = Service.create(wsdlURL, serviceName);
      ServiceIface proxy = (ServiceIface)service.getPort(ServiceIface.class,  new AddressingFeature());
      // invoke method
      proxy.sayHello();
   }
   
}
Copy to Clipboard Toggle word wrap
We now have both JAX-WS client and endpoint communicating with each other using WS-Addressing.
