Java EE (Java Enterprise Edition) General Discussion

Hi

I want to read and save messages to harddisk.
Messages with only TEXT/PLAIN are working.
But multipart messages with attachment or TEXT/PLAIN and TEXT/HTML
causes same result java.io.IOException: No content.

Is this a mail server problem or how to read and save multipart message content with imap.
It's working fine if I use pop3 protocol.

I have try 2 different mailserver and they are not working.
Is there somekind of trick how to read and save message parts?
messages.writeTo(System.out);
Print hole messages headers and content.

Part of the code and session.setDebug(true); trace.
It is modified code to demonstrate problem.

------------------------------------------
...
Store store = session.getStore("imap");
store.connect(host, username, password);
Folder folder = store.getFolder("INBOX");
folder.open(Folder.READ_ONLY);
Message message[] = folder.getMessages();
for (int i=0, n=message.length; i<n; i++) {
System.out.println(i+" ####################################################");
Object content = message[i].getContent();
if (content instanceof Multipart) {
mpart(message[i]);
} else {
System.out.println("Not Multipart message.................("+message[i].getContentType()+")");
}
}

...
public static void mpart(Message message){
for(int i=0;i<2;i++){
try{
Multipart mp = (Multipart)message.getContent();
Part part = mp.getBodyPart(i);

System.out.println("getFileName = "+part.getFileName());
System.out.println("getSize = "+part.getSize());
System.out.println("getLineCount = "+part.getLineCount());
System.out.println("getDisposition = "+part.getDisposition());
System.out.println("getContentType = "+part.getContentType());
System.out.println("getContent = "+part.getContent());

InputStream in = part.getInputStream();
byte[] buf = new byte[1024];
int n = in.read(buf);
}catch(Exception ex){System.out.println(ex.toString());}
}
