Question

Alrighty, so I’m working on making a .jar for a client for a little game and I know how to use everything and have done this before, on windows, now i’m on a mac. This shouldn’t make a difference but incase you wanted to know, there you go.

Now, I have a folder in eclipse named client, now normally the client.java is the main class but there is another named EGUI, this has the “public static void main(String[] args)”, but in my client.java file, it also has a method like this:

 public static final void main(String args[])
{
    try
    {
        anInt957 = 0;
        anInt958 = 0;
        method52(false);//highmem
        aBoolean959 = true;//members
        signlink.storeid = 32;
        signlink.startpriv(InetAddress.getLocalHost());
        client client1 = new client();
        client1.method1(503, false, 765);
        setserver(args[0], "5555");
        return;
    }
    catch(Exception exception)
    {
        return;
    }
}

I guess my question is, does the “final” make it the main file? Or would it still be the EGUI, which looks like this:

import java.awt.BorderLayout;
import java.awt.Cursor;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;

public class EGUI
{ 
public static void main(String args[])
{
                client.main(new String[] {
            "127.0.0.1", "127.0.0.1", "127.0.0.1"
        });
    }
}

So, what i’m asking for is, why is it that when I’m setting the main file to EGUI, it isnt working? the applet opens up, but I keep getting an “error connecting to server” message every time, when I run it through terminal by copying the run.bat info and pasting that, it works perfectly! Any help is greatly appreciated!

Answer 1

public static void main(String args[]) means you can execute the class from the commandline. The final keyword means the method cannot be overridden by a sub class.

In your case this does not make it the jar’s main execution class. The main class is set in META-INF/MANIFEST.MF. Normally it should have a line:

Main-Class: classname

but then with the actual class.

So open the jar with a zip program, and check MANIFEST.MF.

Your client.java has a main method, for testing purposes I suppose.
