NX:About entrance of runme.jar

[xi ruo]

There is a section saying from this thread by Andrew.

The user selects what mode to run it in by using a parameter on the command line:

java -jar runme.jar - the client starts up in networked mode

java -jar runme.jar alone - the client starts up in non networked mode

java -jar runme.jar server - the server starts up

Is there a direct way to implement?
I have a indirect way,following:

import suncertify.gui.*;
import suncertify.remote.*;
public class entrance {
  public static void main(String[] args) {
    try{
      if (args.length>1) {
        throw new Exception("Argument inputed error.");
      }
      else if (args.length == 0) {
        new clientMainFrame(suncertify.gui.GUIController.NETWORK_CONNECTION);
        return;
      }
      else if (args[0].equals("alone")) {
        new clientMainFrame(suncertify.gui.GUIController.LOCAL_CONNECTION);
        return;
      }
      else if (args[0].equals("server")) {
        new RegDatabase();
        return;
      }
      else {
        throw new Exception("Argument inputed error.");
      }
    }catch(Exception e){
      e.printStackTrace();
    }
  }
}

MANIFEST.MF

Manifest-Version: 1.0
Created-By: 1.4.2_01 (Sun Microsystems Inc.)
Main-Class: entrance

a command of this exact form:

jar cvfm runme.jar MANIFEST.MF *.*

Please comment,thanks.

Another question:
What's the single mode flag?

[Andrew Monkhouse]

Hi Xi,
I think the way you handled this is fine.
At some point in everyone's program they will need to look at the command line argument and decide what to do. I believe it makes sense to have a wrapper class just like yours to do this.
I don't believe you need the "return" statements in your code.

What's the single mode flag?

The command line parameter: "alone", "server", <nothing>
