Hello,
first of all, I apologize for my bad English...
I have a problem but I don't know  how I can resolve it.
This is code:

------------------
 PrintOnVideo.java
------------------
package stampa.wservice;
import stampa.data.Ordinabile;

public class PrintOnVideo{

   public String print(Ordinabile o){

System.out.println("E' stato ricevuto un oggetti di classe "+o.getClass().getName());

      return ( o.getClass().getName());
    }
}

------------------
 Ordinabile.java
------------------
package stampa.data;
public interface Ordinabile
{
   public boolean maggioreDi(Ordinabile o);
}

 PrintClient.java
-------------------
package stampa.client;

import javax.xml.namespace.QName;

import org.apache.axis2.AxisFault;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.rpc.client.RPCServiceClient ;

import stampa.data.Carte;


public class PrintClient {

    public static void main(String[] args1) throws AxisFault {

        RPCServiceClient serviceClient = new RPCServiceClient();

        Options options = serviceClient.getOptions();

EndpointReference targetEPR = new EndpointReference(" http://localhost:8080/axis2/services/PrintOnVideo";);

        options.setTo(targetEPR);

        // Setting the weather

QName opPrint = new QName("http://wservice.stampa/xsd ", "print");

    //setto l'oggetto
    Carte obj = new Carte("Re","Nero","Fiori");

        Object[] opPrintArgs = new Object[] { obj };
        Class[] returnTypes = new Class[] { String.class };

Object[] risposta = serviceClient.invokeBlocking (opPrint, opPrintArgs,returnTypes);

    String cclasse = (String) risposta[0];

        if (cclasse == null) {
            System.out.println("Weather didn't initialize!");
            return;
        }

        // Displaying the result
        System.out.println("La risposta e' stata "+cclasse);
    }
}

-------------
 Carte.java
-------------
package stampa.data;

public class Carte implements Ordinabile{

  private String valore, colore, seme;

   public Carte(){
      valore=new String("Asso");
      colore=new String("Rosso");
      seme=new String("Cuori");
   }
   public Carte(String val, String col, String sm){
      this.valore=val ;
      this.colore=col;
      this.seme=sm;
   }

   public boolean maggioreDi(Ordinabile o){
      if (o instanceof Carte){
     Carte p=(Carte)o;
     boolean ok= seme.equals(p.getSeme());
         if ( ok ){
        int x= Integer.parseInt(valore);
        int ox= Integer.parseInt (p.getValore());
        return ( x>ox  );
     }else{return false;}
      }else{return false;}
   }

   String getValore(){return valore;}
   String getColore(){return colore;}
   String getSeme(){return seme;}
}


When I run my client, I have this exception:

I don't know what it means....
How can I resolve my problem?
Thanks very much!!
