Hi, I am trying to run rmi registry and
the rmi Server(TPNServer). The interface
declared in a file(LoginInter) and
implemented in another file(logimpl), and it
is called from TPNServer. But when I execute
the rmi registry and rmi Server I getting
error, Here I given the server coding and
the error occurred.
Code:
import java.rmi.*;
import java.rmi.server.*;
class TPNServer
{
public static void main(
String ar[])
{
try
{
System.out.println("Server Started....");
Tpn t=new TPNImpl();
System.out.println("test-1");
Naming.rebind("Server",t);
}
catch(Exception e)
{
System.out.println("Error
Occurred: "+e);
e.printStackTrace();
}
}
}
Error:
Server Started....
test-1
