How can I connect unity to my smart fox server plugin

I followed a tutorial and had that working but I made a few changes to try and experiment to see how it works but I cant get it to work properly. Right now I tried to edit it so that it would send coordinates to the server and the server would send them back. But I get this error from the server. if you comment to help or try to give a answer I well make sure to thumb it up

if you cant read it open the picture URL to get a larger image http://piclair.com/data/8fopl.jpg

Here is the NetBeans project script

  package PlayerPosExtension;
 
 import com.smartfoxserver.v2.entities.User;
 import com.smartfoxserver.v2.entities.data.ISFSObject;
 import com.smartfoxserver.v2.entities.data.SFSObject;
 import com.smartfoxserver.v2.extensions.BaseClientRequestHandler;
 
 public class PlayerPos extends BaseClientRequestHandler{
 
     @Override
     public void handleClientRequest(User user, ISFSObject objIn) {
       
        int x = objIn.getInt("x");
        int y = objIn.getInt("y");
        int z = objIn.getInt("z");
        
        ISFSObject objOut = new SFSObject();
        objOut.putInt("PosX", x);
        objOut.putInt("PosY", y);
        objOut.putInt("PosZ", z);
        
        send("PosX", objOut, user);
        send("PosY", objOut, user);
        send("PosZ", objOut, user);
     }
     
 }
 

Here is the script in unity
