Unable to Overload toString for Object

Code:

package XMLRPC;

import java.net.MalformedURLException;
import java.net.URL;
import java.util.HashMap;
import java.util.Map;

import org.apache.commons.httpclient.HttpClient;
import org.apache.xmlrpc.XmlRpcException;
import org.apache.xmlrpc.client.XmlRpcClient;
import org.apache.xmlrpc.client.XmlRpcClientConfigImpl;
import org.apache.xmlrpc.client.XmlRpcCommonsTransportFactory;

public class Search {

 
       @Override
    public String toString() {
           //System.err.println ("Ojesh");
           return String.format("oje"+"abx");
    }

    public static void main(String args[])
          throws MalformedURLException, XmlRpcException {

           
           HttpClient httpClient = new HttpClient();
            XmlRpcClient rpcClient = new XmlRpcClient();
            XmlRpcCommonsTransportFactory factory = new XmlRpcCommonsTransportFactory(rpcClient);
            XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl();

          factory.setHttpClient(httpClient);
            rpcClient.setTransportFactory(factory);
            config.setServerURL(new URL("http://abc2/bugzilla/xmlrpc.cgi"));
            rpcClient.setConfig(config);

            //map of the login data
            Map loginMap = new HashMap();
            loginMap.put("login", "abc@bag");
            loginMap.put("password", "***");
            loginMap.put("rememberlogin", "Bugzilla_remember");

           
            
           
            // login to bugzilla
            Object loginResult = rpcClient.execute("User.login", new Object[]{loginMap});
            System.err.println ("loginResult=" + loginResult);

            // map of the bug data ok
            Map bugMap = new HashMap();

            bugMap.put("id", "350");
            
            //bugMap.put("status", "NEW");

            // create bug
            Object createResult = rpcClient.execute("Bug.search", new Object[]{bugMap});
            //createResult.toString();
           
            System.err.println("createResult =" + createResult.toString());
            
           
         }
       
       
     }

Its not returnig OJEABX as expected. Instead bugs=[Ljava.lang.Object;@2ee5e48a being diplayed.
Where am i going wrong.??
