// Register an instance of RemImpl.

3. Create a client, OpTest.java, that uses the remote interface:
package rmi1;
import java.rmi.*;
import java.rmi.server.*;
public class OpTest {
public static void main(String[] args) {
System.setSecurityManager(new RMISecurityManager());
try {
RemOp ro = (RemOp) Naming.lookup("My_Server");
ro.call();
System.out.println("Get server message:["+ro.getString()+"]");
System.out.println("Sending string [client test] to server...");
ro.sendString("client test");
System.out.println("Calling server func doAdd(), send 5 and 3 ...");
System.out.println("the result is " + ro.doAdd(5, 3));
}
catch (Exception x) {
