axis2 and lists

[Kostis Tzanettis <kt...@gmail.com>]

Hello,
I want to make a client ask axis2 for a list of objects. Is that possible;
Using the code below, i can see some of the db information on tomcat's logs
and if i try to send only one field such as LocationName it works fine. But
if I try to send all the objects of the list or even only one object there
is an exception: exception occurred while trying to invoke service  method
getLocation and on tomcat i see a message: Mapping qname not fond for the
package: java.util

at org....
Thank you.

This is the client code:
package gr.ntua.netmode.rpcclient;

import javax.xml.namespace.QName;
import java.util.List;
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 org.apache.log4j.Logger;

import gr.ntua.netmode.myPaper.*;

public class topologyRPCClient {

    private static Logger log =Logger.getLogger(topologyRPCClient.class);

    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/TopologyService
");
            options.setTo(targetEPR);

            QName opGetNode =new QName("http://service.netmode.ntua.gr/xsd",
"getLocation");
            log.debug(opGetNode);

            Object[] opGetNodeArgs = new Object[] { };
            Class[] returnTypes = new Class[] { List.class };
            Object[] response = serviceClient.invokeBlocking (opGetNode,
opGetNodeArgs, returnTypes);

            List result = (List) response[0];
            Location k=(Location) result.get(1);
            System.out.println(k.getCity());


            }

        }
}


and this is the service code:

public List getLocation(Integer id) throws Exception  {

        List <Location> n=null;
        Location x=null;
        String y=null;

        Transaction tx = null;
        SessionFactory sessionFactory = new
Configuration().configure().buildSessionFactory();
        Session session =sessionFactory.openSession();

        System.err.println(session.isConnected());
        System.err.println(session.isOpen());

        try {
            tx = session.beginTransaction();

            System.err.println(tx.isActive());

            n= session.createQuery("from Location as location").list();


            x=n.get(2);
            y=x.getName();

            log.debug(n);
            tx.commit();

            System.out.println(n);
            System.out.println();
            System.out.println(y);
            System.out.println(x.getCountry());
            System.out.println(x.getAltitude());
            System.out.println(x.getEmail_address());
            System.out.println ();
        }
         catch (HibernateException e) {
            e.printStackTrace();
            if (tx != null && tx.isActive())
                tx.rollback();
        }

        return n;
    }
