问题
I am creating an application to send mail with an attachment. When I attach a small zip file it is working perfectly but when i attach a larger (> 1mb) zip file it is returning the error "java.net.SocketException: Software caused connection abort: socket write error" and my application is hanging.
my code to attach the files is:
protected void addAtachments(String[] attachments, Multipart multipart)
throws MessagingException, AddressException {
System.out.println("attaching");
for (int i = 0; i <= attachments.length - 1; i++) {
String filename = attachments[i];
MimeBodyPart attachmentBodyPart = new MimeBodyPart();
//use a JAF FileDataSource as it does MIME type detection
DataSource source = new FileDataSource(filename);
attachmentBodyPart.setDataHandler(new DataHandler(source));
attachmentBodyPart.setFileName(filename);
//add the attachment
multipart.addBodyPart(attachmentBodyPart);
System.out.println("attachment added: " +attachments[i]);
}
Also, is there any way to attach the file faster using javamail? It is taking too much time to send attached message.

if attached file is small it is working but taking 10 to 11 minutes to send mail
I am using Jfilechooser to select files to attach
回答1:
The server may be timing out the connection because it's taking too long to send the message to the server. Turn on session debugging and the protocol trace may provide more information.
Where is the zip file stored? Is it on the local disk where the JavaMail application is running?
