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.

Good stuff! Some smileys in the listings, though - I think you need to turn off a plugin...

Thanks Pat for the comment! I thought those smileys were cute :) But to be meaningful and listening to my readers, turned off the plugin.

Awesome stuff.. very helpful. Can you give me the code how to write for login page using web service in java. It would be helpful. thank you

saikrishna, The code will be no different that invoking any other Web service. You just need to make sure your client-side artifacts are bundled in the WAR file though.

Great example!

I need to be able "runtime" to choose wsit config file. One way would be to have multiple "WEB-INF/..xml" and add exactly one of them to the jvm classpath.

A dream scenario would be if I could do this programmatically at startup, like WSITEnginde.setConfig("mywsit.xml"). It might be possible when looking at the PolicyConfigParser.java ..

Rickard, it would be easier to discuss your scenario on the mailing list users@metro.dev.java.net: https://metro.dev.java.net/servlets/ProjectMailingListList

You are having at least two options, both of which are a bit lengthy to explain. I am working on a blog entry right now and will have that ready and published by Monday at the latest. I will keep you posted.

Tjenare, Fabian

Rickard, I am discussing the options you are having here: http://blogs.sun.com/ritzmann/entry/non_standard_wsit_configuration_file

Hi, I have a problem of accessing web service methods, I have user name and password and I am using netbeans 6 but I don't know how to use them. I developing web service client. Server have been developed by other programmer they just given me wsdl file only.
I always I get this kind of exception
