How to access a secure webservice

To access a secured web service is explained below in 3 steps
 
Step 1:
 Create skelton using wsdl2java command, configure the bean in spring XML as below

XML

<jaxws:client id="wsCall"
                      serviceClass="x.x.x..WSCall"
                      address="url?wsdl" />
 Step:2

Create a test program to invoke WS as explained below.

WebServiceTest  

package x.x.x.x;

import java.util.HashMap;

import org.apache.cxf.endpoint.Client;
import org.apache.cxf.endpoint.Endpoint;
import org.apache.cxf.ws.security.wss4j.WSS4JOutInterceptor;
import org.apache.ws.security.WSConstants;
import org.apache.ws.security.handler.WSHandlerConstants;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import x.x.x.x.WSCall;
import x.x.x.x.WSResponse;


public class WebServiceTest {

     protected static final String CHAR_ENCODING = "UTF-8";
    /**
     * @param args
     */
    public static void main(String[] args) {
       
            try {
               
               
                ApplicationContext context = new ClassPathXmlApplicationContext(new String[] {"path.xml"});
                WSCall wsCall= (WSCall) context.getBean("wsCall");
               
               HashMap outProps = new HashMap();
               Client client = org.apache.cxf.frontend.ClientProxy.getClient(wsCall);//servPort);
                Endpoint cxfEndpoint = client.getEndpoint();

                outProps.put(WSHandlerConstants.ACTION, WSHandlerConstants.USERNAME_TOKEN);
                outProps.put(WSHandlerConstants.USER, "user");
                outProps.put(WSHandlerConstants.PASSWORD_TYPE, WSConstants.PW_DIGEST);

                outProps.put(WSHandlerConstants.ADD_UT_ELEMENTS, WSConstants.NONCE_LN + "" + WSConstants.CREATED_LN);

                outProps.put(WSHandlerConstants.PW_CALLBACK_CLASS, ClientPasswordCallback.class.getName());

                WSS4JOutInterceptor wssOut = new WSS4JOutInterceptor(outProps);
                cxfEndpoint.getOutInterceptors().add(wssOut);

                       
                WSResponse wsResponse = wsCall.invoke(params...);
               
       
            } catch (Exception e) {
                e.printStackTrace();
            }
         
    }
   
   
}

 Step:3

Create a password generation class

ClientPasswordCallback

package x.x.x.x;
import java.io.IOException;
import javax.security.auth.callback.Callback;
import javax.security.auth.callback.CallbackHandler;
import javax.security.auth.callback.UnsupportedCallbackException;
import org.apache.ws.security.WSPasswordCallback;

public class ClientPasswordCallback implements CallbackHandler {

    public void handle(Callback[] callbacks) throws IOException,
        UnsupportedCallbackException {

        WSPasswordCallback pc = (WSPasswordCallback) callbacks[0];

        // set the password for our message.
        pc.setPassword("password");
    }

}

Run the WebServiceTest program to invoke secure Webservice.
