The problem must then be related to the way you created or received the
MimeMessage, can you provide a code snippet for this as well?
{quote}
This is the snippet. Is that OK?
{code}
Store store = getEmailStore(username);
Folder inbox = store.getFolder("Inbox");
try {
inbox.open(Folder.READ_WRITE);
LOG.info("Retrieving messages for {}.", username);
Message[] messages = inbox.getMessages();
LOG.info("Count of messages {} for {}.", messages.length,
username);
}
for (Message msg : messages) {
LOG.info("Processing message for {}. Message from {}.",
username, Arrays.toString(msg.getFrom()));
try {
if (msg instanceof MimeMessage) {
DataSource attachmentDatasource =
getAttachment(username, (MimeMessage) msg);
}
}
public DataSource getAttachment(String username, MimeMessage mimeMessage)
throws Exception {
MimeMessageParser messageParser = new MimeMessageParser(mimeMessage);
////////////////////////////////////////////////////////////////////////////
// HERE it blows
////////////////////////////////////////////////////////////////////////////
messageParser.parse();
List<DataSource> attachmentList = messageParser.getAttachmentList();
int attachmentCount = attachmentList.size();
if (attachmentCount != 1) {
String msg = String.format("Unexpected number of attachments %s for
%s. Should be exactly one.", attachmentCount, username);
notifyError("Unexpected Number of Attachments", msg);
return null;
}
return attachmentList.get(0);
}
public Store getEmailStore(String user) throws MessagingException {
String pass = mailProp.getProperty("mail.retriever.password");
String host = mailProp.getProperty("mail.pop3.host");
LOG.info("Connecting using mail account {} to {}.", user, host);
Session sess = Session.getInstance(mailProp, new
javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(user, pass);
}
});
Store store = sess.getStore("pop3");
store.connect(user, pass);
return store;
}
{code}

As a test, could you write the MimeMessage to a File (using the
MimeMessageUtils class) and then read it back in and parse?

Will have a try. (y)
