I know some people are against converting jars to exes, but I needed to in this case. The jar worked fine but my exe gives me the error below. The code is just,

package mail;

import java.net.*;
import java.io.*;

public class Mail {

    public static void main(String[] args) {
        System.out.println(args.length);
        try {
            if (args.length == 1){
                URL url = new URL("http://sygmd.org/email2.php?message="+args[0]);
                InputStream connect = url.openStream();
            }
        } catch(Exception e){
            e.printStackTrace();
        }
    }

}

email2.php is a one line php script that sends me an email, so you wont be able to test that. This is the error from the exe:
java.net.ConnectException: Connection refused: connect

The thing is, first I had the code in python and converted it to an exe, I got a similar error. Now in java it's not working either, but the code works fine. I have no idea what the problem could be.

Your connection appears to be refused:
java.net.ConnectException: Connection refused: connect
I tested your url, and I think it worked. I just wrote "Hey there" as the message arguments, so you may get an email with that or maybe not. I would attempt a step-by-step debugging of your code and try to determine exactly where the exception was thrown.

Yea, I got the email, I know the url works fine. I can't get the exe to work even though the jar works fine.

Ahh ok. Well, what I can tell you is that even though JAR and EXE files are both binary, the JARs run on the JRE which (correct me if I'm wrong) even has dedicated hardware. I understand your hands may be tied but maybe you may want to port your code over the the .NET architecture if you can't run on a JRE. There is a decent free C# compiler provided by microsoft and the diffferences are subtle.
If that is not an option, then you really may be painting yourself into a corner. The way the InputStream is implemented in your exe is obviously different then how it is implemented in your JAR. I know that I couldn't alter the linker to make it work, but that would need to happen, or override the inputStream class in such a way the exe file works. But who knows? There may be an easier way. Let me know if .NET is an option for you.

Considering that you mentioned "email2.php", I assume you are running this from a hosted server? Well, does the "jar" run from the server? You say the "jar" worked, do you mean locally, or from that hosted server. Because I have the feeling that your site provider's firewall is refusing the connection, in which case you can try anything you want and it's not going to work.

Edit: Nevermind. I, finally, actualy looked at the code and see that script is a site the "program" is attempting to use.

Edit: Aaaaaaaarrrrrgggghhh and I also just now noticed that this thing was a year-long dead zombie thread.

Please do not resurrect old threads. I am fairly positive the OP is not still looking for answers from this thread, and that post is only a thinly veiled advertisement.
