Send email Google App Engine (GAE)

[Aline Nunes]

Hello everyone,

I am getting the following error from my code that send email from Google App Engine

com.google.apphosting.api.ApiProxy$CallNotFoundException: The API package 'mail' or call 'Send()' was not found.
	at com.google.apphosting.api.ApiProxy.makeSyncCall(ApiProxy.java:109)
	at com.google.apphosting.api.ApiProxy.makeSyncCall(ApiProxy.java:64)
	at com.google.appengine.api.mail.MailServiceImpl.doSend(MailServiceImpl.java:101)
	at com.google.appengine.api.mail.MailServiceImpl.send(MailServiceImpl.java:34)

	at javax.mail.Transport.send(Transport.java:95)
	at javax.mail.Transport.send(Transport.java:48)

I've tried to use the solution suggested in this forum ...

http://stackoverflow.com/questions/2...oyed-to-tomcat

But without success!

Please anyone who can suggest a solution, I will be grateful!

This is my code in Java:

import java.io.UnsupportedEncodingException;
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;



public class EmailJava {

    public EmailJava() {

    }

    public void enviaEmail() throws UnsupportedEncodingException {
        Properties props = new Properties();
        Session session = Session.getDefaultInstance(props, null);

        String Mensagem = "teste";

        try {
            Message msg = new MimeMessage(session);
            msg.setFrom(new InternetAddress("[e-mail]", "User"));
            msg.addRecipient(Message.RecipientType.TO, new InternetAddress("[e-mail]", "Mr. User"));
            msg.setSubject("Sua conta Example.com foi ativado");
            msg.setText(Mensagem);
            Transport.send(msg);

        } catch (AddressException e) {
            e.printStackTrace();
        } catch (MessagingException e) {
            e.printStackTrace();
        }
    }

}

Few things I would check:

- Does this problem happen only in the local server, but not when deployed?

- Are you sure you are NOT including the Javamail JAR files in the classpath? (Appengine SDK has the Javamail stuff embedded, which is what you should use)

- Are you sure the sender ID (which is "[email protected]" in your example) has administrative permissions, at least in a 'viewer' role?
