Java - Default Mail Client

When you want to direct client to mail sending, you can use java.awt.Desktop.
Here is an example:

article

import java.awt.*;
import java.io.IOException;
import java.net.URI;

public class RunningDefaultMailClient {
public static void main(String[] args) {
//
// Get an instance of Desktop. If the platform doesn't
// support Desktop API an UnsupportedOperationException
// will be thrown.
//
Desktop desktop = Desktop.getDesktop();

try {
//
// Open user-default mail client application.
//
desktop.mail();
} catch (IOException e) {
e.printStackTrace();
}

try {
//
// Open user-default mail client with the email message
// fields information.
//
// mailto:dummy@domain.com?cc=test@domain.com&
// subject=First%20Email&&body=Hello%20World
//
String message = "mailto:dummy@domain.com?subject=First%20Email";
URI uri = URI.create(message);
desktop.mail(uri);
} catch (IOException e) {
e.printStackTrace();
}
}
}
