Sorry, been sick for a while. Here is the complete source working on
1.3 release of GAE/J:
public class MailHandler extends HttpServlet {
private static final long serialVersionUID = 895612806305910032L;
private final Logger logger = Logger.getLogger(getClass().getName());
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException {
final Session session = Session.getDefaultInstance(new
Properties(),
null);
try {
final MimeMessage message = new MimeMessage(session,
request.getInputStream());
final StringBuffer sb = new StringBuffer();
sb.append("From: ");
final Address[] senders = message.getFrom();
for (int i = 0; i < senders.length; i++)
sb.append(senders[i].toString()).append("; ");
sb.append("\n");
sb.append("To: ");
final Address[] receivers = message.getAllRecipients();
for (int i = 0; i < receivers.length; i++)
sb.append(receivers[i].toString()).append("; ");
sb.append("\n");
final Object content = message.getContent();
if (content instanceof String)
sb.append((String) content);
else if (content instanceof MimeMultipart) {
final MimeMultipart mmp = (MimeMultipart)
content;
for (int i = 0; i < mmp.getCount(); i++) {
final Part p = mmp.getBodyPart(i);
final Object bp = p.getContent();
if (bp instanceof String)
sb.append((String) bp);
}
}
final TaskOptions taskOptions =
TaskOptions.Builder.url("***");
taskOptions.param("sender", "***");
taskOptions.param("receiver", "***");
taskOptions.param("subject", "FW: " +
message.getSubject());
taskOptions.param("body", sb.toString());
QueueFactory.getDefaultQueue().add(taskOptions);
} catch (MessagingException e) {
logger.log(Level.SEVERE, null, e);
}
}
}
