Tango on JavaSE 6

Fabian explained how WSIT features can be configured on Java SE 6 Endpoint API exposed as part of JAX-WS 2.1. In this blog, I start with a Reliable Messaging-enabled endpoint developed using NetBeans IDE 5.5.1 and WSIT plug-in and then provide detailed steps, along with code, to deploy it in Java SE 6.

1. Create a Reliable Web service endpoint using WSIT plug-in and NetBeans 5.5.1 by watching this screencast.
2. Download and install WSIT Milestone 5. Copy webservices-api.jar in Java SE 6 'jre\lib\endorsed' directory.
3. All the capabilities enabled at an endpoint, such as Reliable Messaging for this one, are stored in the WSIT configuration file. In NetBeans IDE, expand your Project, 'Web Pages', 'WEB-INF'. The configuration file be named something similar to 'wsit-server.HelloWebService.xml' following the format 'wsit-<packageName>.<ServiceName>.xml'. Here is how the config file looks like:
   

   	
   <?xml version="1.0" encoding="UTF-8"?> 
   <definitions 
       xmlns="http://schemas.xmlsoap.org/wsdl/" 
       xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" 
       xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
       xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" name="HelloWebServiceService" 
       targetNamespace="http://server/"
       xmlns:tns="http://server/" 
       xmlns:wsp="http://schemas.xmlsoap.org/ws/2004/09/policy" 
       xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" 
       xmlns:wsaws="http://www.w3.org/2005/08/addressing"
       xmlns:wsrm="http://schemas.xmlsoap.org/ws/2005/02/rm/policy">
       <message name="sayHello"/>
       <message name="sayHelloResponse"/>
       <portType name="HelloWebService">
           <wsdl:operation name="sayHello">
               <wsdl:input message="tns:sayHello"/>
               <wsdl:output message="tns:sayHelloResponse"/>
           </wsdl:operation>
       </portType>
       <binding name="HelloWebServicePortBinding" type="tns:HelloWebService">
           <wsp:PolicyReference URI="#HelloWebServicePortBindingPolicy"/>
           <wsdl:operation name="sayHello">
               <wsdl:input/>
               <wsdl:output/>
           </wsdl:operation>
       </binding>
       <service name="HelloWebServiceService">
           <wsdl:port name="HelloWebServicePort" binding="tns:HelloWebServicePortBinding"/>
       </service>
       <wsp:Policy wsu:Id="HelloWebServicePortBindingPolicy">
           <wsp:ExactlyOne>
               <wsp:All>
                   <wsaws:UsingAddressing xmlns:wsaws="http://www.w3.org/2006/05/addressing/wsdl"/>
                       <wsrm:RMAssertion/>
               </wsp:All>
           </wsp:ExactlyOne>
       </wsp:Policy>
   </definitions>

   Copy this config file by the name wsit-server.HelloWebService.xml in META-INF directory in your classpath.
4. The Web service implementation class looks like:
   

   package server;
   
   import javax.jws.*;
   
   @WebService(targetNamespace="http://server/")
   public class HelloWebService {
       @WebMethod
       public String hello(@WebParam(name="name")String text) {
           return "Hello " + text;
       }
   
   }
   

   As you see, this is a plain JAX-WS Web service endpoint class.
5. The JAX-WS Endpoint code that starts the Web service endpoint looks like:
   

   package server;
   
   import java.io.IOException;
   import javax.xml.ws.Endpoint;
   
   public class Main {
   
      private static final int PORT = 58888;
      private static final String HOST = "localhost";
   
      public static void main(String[] args) {
           Endpoint endpoint = Endpoint.create(new HelloWebService());
           String address = "http://" + HOST + ":" + PORT + "/";
           endpoint.publish(address);
           System.out.println("Endpoint hosted at ... " + address);
      }
   }
   

6. The sequence of commands to deploy the endpoint is:
   

   "\Program Files\Java\jdk1.6.0_01\bin\javac.exe" -d . server\*.java
   "\Program Files\Java\jdk1.6.0_01\bin\wsgen.exe" -cp . server.HelloWebService
   java -classpath .;\jax-ws-latest-wsit\lib\webservices-rt.jar server.Main

7. And then you see the following output on the command prompt:
   

   java -classpath .;C:\testbed\jax-ws-latest-wsit\lib\webservices-rt.jar server.Main

That's it, the endpoint now deployed at 'http://localhost:58888/MyService?wsdl' is Reliable Messaging enabled. This endpoint can be invoked using any of the methods shown here.
