Error in invoking webservice using axis

Question

Here is my code: I get an error saying No Deserializer found to deserialize a 'http://schemas.xmlsoap.org/soap/encoding
/:string' using encoding style 'http://schemas.xmlsoap.org/soap/encoding/'.
Please advice on what do I need to do
======================================
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import javax.xml.namespace.QName;
import java.net.*;
public class Traffic {
public static void main(String [] args) throws Exception {
     try{
Service service = new Service();
Call call = (Call)service.createCall();
String endpoint = "http://services.xmethods.net:80/soap/servlet/rpcrouter";
call.setTargetEndpointAddress(new URL(endpoint));
call.setOperationName( new QName("urn:xmethods-CATraffic", "getTraffic") );
     //call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);
String hwnum = "101"; // get a highway number
          System.out.println("hehre");
     //System.out.println("Here"+call.invoke(new Object [] {new String(hwnum)}));
String answer =
(String)call.invoke(new Object [] {new String(hwnum)});
System.out.println("Got result : " + answer);
     }catch(Exception e){
               System.out.println(e);
}
