Hey Felipe,
Here is what you need to do:
Client Side :
SendEmail.java (Entrypoint or a Popup) - A very basic design would be of
a TextArea / RichTextArea where you can have the body of the email written.
Then you can provide a "Send" Button. On the click of the send button,
create an object of the Async class and call the SendEmail function with the
String parameter.
SendEmailService.java - A simple method with a String parameter,
something like this.
public void SendEmail(String body) throws Exception.
SendEmailServiceAsync.java - A simple method again with a String
parameter this way:
public void SendEmail(AsyncCallback<Void> callback).
Server Side:
SendEmailServiceImpl.java - Implement the function I had sent earlier and
you shud be able to send the email with that successfully.
Note : If you want to send other parameters like username etc from the
client side, then I would advise using a Vo rather than a String parameter
alone.
Hope this helps..
Let me know if u need any other help. No matter how silly.. (I have asked
sillier doubts when I had started understanding GWT, he he)
Regards,
Abhi
