How do I launch user-default mail client application?

By Wayan in AWT, Core API 0 Comment

Here is an example using the java.awt.Desktop class to open user’s default mail client application. There are two methods provided, the mail() and the mail(URI uri) methods.

When specifying the URI to the application will be opened with the message field filled with the mailto information. You can refer to the following document for the valid mailto URI scheme http://www.ietf.org/rfc/rfc2368.txt

package org.kodejava.awt;

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. An UnsupportedOperationException will
        // be thrown if the platform doesn't support Desktop API.
        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.
            String message = "mailto:dummy@example.com?cc=test@example.com&subject=First%20Email";
            URI uri = URI.create(message);
            desktop.mail(uri);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
