Hi,
How can make this client code work in Struts ?
Please see two pieces of comparative client code , common RMIInterface
interface , and struts problem report :-
package org.apache.struts.helloworld.model;
import java.net.MalformedURLException;
import java.rmi.Naming;
import java.rmi.NotBoundException;
import java.rmi.RemoteException;
import org.acme.rmi.RMIInterface;;
public class MessageStore {
private String message;
private static RMIInterface look_up;
public MessageStore() throws MalformedURLException,
RemoteException, NotBoundException
{
look_up = (RMIInterface) Naming.lookup("//localhost/MyServer");
String response = look_up.helloTo("coco");
message = "Hello Struts User" + response;
}
public String getMessage() {
return message;
}
}
Other working client code this works :
package org.acme.rmiclient;
import java.net.MalformedURLException;
import java.rmi.Naming;
import java.rmi.NotBoundException;
import java.rmi.RemoteException;
import javax.swing.JOptionPane;
import org.acme.rmiinterface.RMIInterface;
public class ClientOperation {
private static RMIInterface look_up;
public static void main(String[] args)
throws MalformedURLException, RemoteException, NotBoundException {
look_up = (RMIInterface) Naming.lookup("//localhost/MyServer");
String txt = JOptionPane.showInputDialog("What is your name?");
String response = look_up.helloTo(txt);
JOptionPane.showMessageDialog(null, response);
}
}
package org.acme.rmi;
import java.rmi.Remote;
import java.rmi.RemoteException;
public interface RMIInterface extends Remote {
public String helloTo(String name) throws RemoteException;
}
