Hello Sandro, Are you repackaging the JavaMail JAR from Oracle (from http://www.oracle.com/technetwork/java/javamail/index.html )? If so, you need to delete those JARs. Google App Engine packages its own custom implementation of JavaMail, you're not allowed to override that with your own library.
If you're still having trouble, you might be interested in using GAE's low level mail API. Documentation is located here: https://developers.google.com/appengine/docs/java/javadoc/com/google/appengine/api/mail/MailService . It's easy to use, just create a com.google.appengine.api.mail.MailService.Message object, configure it with To, From, Subject, and Body fields, and send it using Mailservice.send. ----------------- -Vinny P Technology & Media Advisor Chicago, IL My Go side project: http://invalidmail.com/ On Friday, April 19, 2013 9:44:55 AM UTC-5, Sandro Stricker wrote: > > Hello, > > I've got a problem sending a mail from my GAE project. here is my code: > > > > > > > > > Properties props = new Properties(); > > Session session = Session.getDefaultInstance(props, null); > > String msgBody = "..."; > > try { > > Message msg = new MimeMessage(session); > > msg.setFrom(new InternetAddress("[email protected]<javascript:> > ", "Example.com Admin")); > > msg.addRecipient(Message.RecipientType.TO,new InternetAddress( > "[email protected] <javascript:>", "Mr. User")); > > msg.setSubject("Your Example.com account has been activated"); > > msg.setText(msgBody); > > Transport.send(msg); > > > > } catch (AddressException e) { > > } catch (MessagingException e) { > > } > > I get errors like: > > javax.mail.Message is not supported by Google App Engine's Java runtime > environment > > What's the problem here? > > -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
