I am following the http://code.google.com/appengine/docs/java/mail/overview.html
instructions.
My code (snippets):
import java.io.PrintWriter;
import java.io.UnsupportedEncodingException;
import java.util.Properties;
import java.util.logging.Logger;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public void execute(HttpServletRequest request, HttpServletResponse
response, PrintWriter out) {
String userName = System.getProperty
("com.galensystems.calendarEmail");
String body = "This is a test";
Properties props = System.getProperties();
// Get a Session object
Session session = Session.getInstance(props, null);
Message message = new MimeMessage(session);
try {
message.setFrom(new InternetAddress(userName, "Admin
Email"));
message.addRecipient(Message.RecipientType.TO,
new
InternetAddress("[email protected]", "Mr. John
Smith"));
message.setSubject("Your Example.com account has been
activated");
message.setText(body);
Transport.send(message);
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (MessagingException e) {
e.printStackTrace();
}
}
After deploying and running it on GAE, I got the following log info/
warning exceptions below. I did not add Sun's JavaMail JARs to my app.
It did send the email successfully. It showed up on my inbox as
expected.
My environments: GAE 1.3.0, Eclipse-Galileo.
Do I need to worry about the exceptions below?
Thanks in advance for your help.
