WSIFException : invoking service method

[Rizwan Patel]

Hi everybody,I am a beginner in the web-service concept.
I want to invoke the service methods dynamically.So i use the WSIF framework to invoke the web-service method.
I have exposed only one method sayHello. When trying to invoke the service thru the client code i get WSIFException :

My client code is as below :
Client side code HelloWorld.java
package clientsidecode.HelloClient;

import java.util.Iterator;
import org.apache.wsif.WSIFMessage;
import org.apache.wsif.WSIFOperation;
import org.apache.wsif.WSIFPort;
import org.apache.wsif.WSIFService;
import org.apache.wsif.WSIFServiceFactory;

import javax.xml.namespace.QName;
public class HelloWorld {

/**
* @param args
*
*/

public static void main(String[] args) throws Exception {
System.out.println("Start -- 1");
String str1="Rizwan";



WSIFServiceFactory factory = WSIFServiceFactory.newInstance();
String wsdlloc="http://localhost:8080/axis2/services/HelloWorld?wsdl";
System.out.println(" -- 2 --");
WSIFService service = factory.getService(wsdlloc,null,null ,"http://hello","HelloWorldPortType");
service.mapType(new QName("http://hello/xsd","HelloWorld"),Class.forName("clientsidecode.HelloClient.HelloWorld"));
WSIFPort port = service.getPort("HelloWorldSOAP11port_http");
System.out.println("-- 3--");
WSIFOperation operation=port.createOperation("sayHello");
WSIFMessage input = operation.createInputMessage("str_1");
WSIFMessage output =operation.createOutputMessage();
WSIFMessage fault = operation.createFaultMessage();
input.setObjectPart("str_1",str1);
String str_2="Hi";
System.out.println("Input Message"+input);
System.out.println("Input parts : "+input.getObjectPart("str_1"));
//input.setObjectPart("part1",str_2);

if(operation.executeRequestResponseOperation(input,output,fault))
{
System.out.println("Result : "+output.getIntPart("return"));
}
// TODO Auto-generated method stub
System.out.println("End");

}

}

Output log
