The situation is like this:
First, we generate a file in the memory, we can get a
Second the InputStream object must be send as a attachment of a email. The language is Java, we use Spring to send email.
I have found a lot of information, but I cannot find how to send an email attachment using
InputStream. I try to do like this:
InputStreamSource iss= new InputStreamResource(new FileInputStream("c:\\a.txt")); MimeMessageHelper message = new MimeMessageHelper(mimeMessage, true, "UTF-8"); message.addAttachment("attachment", iss);
But I get an exception:
Passed-in Resource contains an open stream: invalid argument. JavaMail requires an InputStreamSource that creates a fresh stream for every call.
