Re: How to send an Email with GWT to a specific Address?

[wingdings]

To send an email message, an app prepares a MimeMessage object, then sends 
it with the static method send() on the Transport class. The message is 
created using a JavaMail Session object. The Session and the Transport work 
with the App Engine Mail service without any additional configuration.

import java.util.Properties;

import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

// ...
Properties props = new Properties();
Session session = Session.getDefaultInstance(props, null);

String msgBody = "...";

try {
Message msg = new MimeMessage(session);
msg.setFrom(new InternetAddress("ad...@example.com", "Example.com 
Admin"));
msg.addRecipient(Message.RecipientType.TO,
 new InternetAddress("u...@example.com", "Mr. 
User"));
msg.setSubject("Your Example.com account has been activated");
msg.setText(msgBody);
Transport.send(msg);

} catch (AddressException e) {
// ...
} catch (MessagingException e) {
// ...
}

add click handler to horizontalPanel in gwt

[wingdings]

how do i add click handlers to horizontalPanel ? it worked with the use of 
addDomHandler() but i had to downgrade GWT version for some other reasons , 
and GWT 2.0.4 doesnt support it
i used to do it like this

horizontalPanel.getWidget(1).addDomHandler(someClickHandler,ClickEvent.getType());
//or
horizontalPanel.addDomHandler(someClickHandler, ClickEvent.getType());
