tetest, thank you, the complete working example would be then:
MimeMessage message = new MimeMessage(session,
request.getInputStream());
StringBuffer sb = new StringBuffer();
sb.append("From: ");
Address[] senders = message.getFrom();
for (int i = 0; i < senders.length; i++)
sb.append(senders[i].toString()).append("; ");
sb.append("\n");
sb.append("To: ");
Address[] receivers = message.getAllRecipients();
for (int i = 0; i < receivers.length; i++)
sb.append(receivers[i].toString()).append("; ");
sb.append("\n");
InputStream is = (InputStream) message.getContent();
String contentType = message.getContentType();
ByteArrayDataSource byteArrayDataSource = new
ByteArrayDataSource
(is, contentType);
Multipart mmp = new MimeMultipart(byteArrayDataSource);
for (int i = 0; i < mmp.getCount(); i++) {
Part p = mmp.getBodyPart(i);
if ("text/plain".equals(p.getContentType())) {
if (i > 0) sb.append("*******");
ByteArrayInputStream bais =
(ByteArrayInputStream) p.getContent
();
byte[] buffer = new byte[1024];
int length = 0;
while ((length = bais.read(buffer)) !=
-1)
sb.append(new String(buffer, 0,
length));
}
}
Does not work reliably (java.io.IOException: Truncated quoted
printable data and java.lang.OutOfMemoryError: Java heap space) but
that is either other bug in GAE or my code.
