Obviously you have a very skewed view of the world
based on what you want to do. The most common thing
people want to do with email is not send raw binary data.
The most common thing people want to do is send text to be
read by a human.
Nonetheless, it's very easy to send binary data. Again, the
most common case is sending text. The thing that's important
with text is that it appear as the same text at the other end.
That's easy. But if you have text where every CR, LF, and
space has to appear absolutely unchanged at the other end,
that requires a bit of extra work.
The demo program sendfile.java that comes with JavaMail
shows how to send a file as an attachment. That's the core
of the program. Here's the 6 lines of code you need to add
to that program to do what you want:
------- sendfile.java -------
100c100,104
< FileDataSource fds = new FileDataSource(filename);
FileDataSource fds = new FileDataSource(filename) {
public String getContentType() {
return "application/octet-stream";
};113a118,119
msg.saveChanges();
mbp2.setHeader("Content-Transfer-Encoding", "base64");Is that so hard?
If you don't want to send the file as an attachment, but rather as the one
and only body of the message, it's even easier. Let me know if I need
to write that program for you as well.
And if you already have the data in memory in a byte array, that's even
easier still.
