Trying to test the rmi tutorial via Netbeans to set up a remote server - client interface. When running the server the following exception appears:
exception: java.rmi.ServerException: RemoteException occurred in server thread; nested exception is: java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is: java.lang.ClassNotFoundException: remotetests.MyRemoteInterface
The rmi registry is running in the background.
It seems the server is unable to publish the remote object?? Below are server, remote interface and client classes
Please help - Thanks!
The server class looks like this:
package remotetests;
import java.io.Serializable;
import java.net.InetAddress;
import java.rmi.*;
import java.rmi.registry.LocateRegistry;
import java.rmi.server.*;
public class MyRemoteClass extends UnicastRemoteObject implements MyRemoteInterface, serializable {
public MyRemoteClass() throws RemoteException {
//Constructor code
System.out.println("MyRemote constructor");
}
public void myMethod1() throws RemoteException {
//Here we put the code we want
System.out.println("I am in myMethod1()");
}
public int myMethod2() throws RemoteException {
return 5; //Here we put the code we want
}
public void anotherMethod() {
//If we define another method, this can´t be called in a remote way unless we call it from the remote interface
}
public static void main(String[] args) {
try {
System.out.println("running main");
MyRemoteInterface mir = new MyRemoteClass();
InetAddress address = java.net.InetAddress.getLocalHost();
System.out.println("host name : " + address.getHostName());
//Naming.rebind("//"+java.net.InetAddress.getLocalHost().getHostAddress() "/RMI_Test", mir);
LocateRegistry.getRegistry().rebind("//"+java.net.InetAddress.getLocalHost().getHostAddress(), mir);
//System.out.println("Server started. Bound RMI test");
} catch (Exception e) {
System.err.println("exception: " + e);
}
}
}
The remote interface class:
package remotetests;
import java.rmi.*;
public interface MyRemoteInterface extends Remote {
public void myMethod1() throws RemoteException;
public int myMethod2() throws RemoteException;
}
The client class:
package remotetests;
public class MyRMIClient {
public void MyRMIClient(String[] args){
try{
MyRemoteInterface mir = (MyRemoteInterface) java.rmi.Naming.lookup("//"+args[0] +":" +args[1]+"/RMITest");
//MyRemoteInterface mir = (MyRemoteInterface) java.rmi.Naming.lookup("//127.0.0.1:1099/RMITest/");
//We print myMethod1() as much as we get back myMethod2()
int monitor = mir.myMethod2();
for(int i=1;i<mir.myMethod2();i++){
mir.myMethod1();
}
}catch (Exception e){
e.printStackTrace();
}
}
}*
