[Fabrice Claeys]

Hello,

I have a problem with sending email in HTML format from GAE with Play!.

Here the trace:

You cannot use play email library with GAE, this is a limitation from GAE. You have to use the email service from GAE:

Hmm, actually I am not so sure about it anymore. It used to be different, I don't really know what is happening, I need to do more research.

Thank's Nicolas

Actually I can send email from play and gae with txt template but not with HTML template.

I solve my problem by overriding the Mailer.send() and don't use the commons-email lib but following the google documentation

http://code.google.com/appengine/docs/java/mail/

[Pascal Voitot Dev]

In your opinion, would it possible to integrate that in the GAE plugin so that it overrides classical Play! email API following Google recommendations?

But commons-email is bassed on JavaMail API according to
http://svn.apache.org/viewvc/commons/proper/email/trunk/src/java/org/apache/commons/mail/Email.java?revision=1031900&view=markup (line 1130)

So it "should" work with commons-email.

the problem for me, is in the GMTransport.java. It check if the mail to send a String instance, otherwise throw the Exception (I had to decompile it using JAD....). The things that I don't understand, is : if the message sent is not a String, what it is ? Obviously, and if I'm not mistaken, this problem doesn't not occur in local, so it's not so easy to debug :P

Yes, the problem doesn't occur in local.

Hello Pascal,

I begin to be satisfied with my solution, but I have a problem in the management
of attachments.

Concerning the integration in the GAE module,  I do not know how to do
yet.

Hi Fabrice,

Can you please share your code on how you send an HTML email on GAE?

Thanks

Amit

Got it working by overriding the send method of the mailer and using this:

Properties props = new Properties();

Session emailSession = Session.getDefaultInstance(props, null);

Multipart mp = new MimeMultipart();

MimeBodyPart htmlPart = new MimeBodyPart();

htmlPart.setContent(bodyHtml, "text/html");

mp.addBodyPart(htmlPart);

msg.setContent(mp);

Transport.send(msg);

Cheers

Amit
