RE: JavaMail: Implement DataSource in javax.activation package

["Clapham, Paul" <pclapham@xxxxxxxxxxxxx>]

You have only four methods to implement, like this:

getContentType(): return a string containing the MIME type of whatever's in
the input stream.  You'd have to have some way of setting or determining
this.

getInputStream(): return the input stream that you passed into the object
via its constructor.

getName(): probably irrelevant.

getOutputStream(): throw an IOException.

Subject: JavaMail: Implement DataSource in javax.activation package


In my java program I need to send some generated contents as e-mail
attachment. But I found that the javax.activation only comes with a
FileDataSource that implements DataSource. This can be used to send a file:

DataSource source = new FileDataSource(filename);

 How do I implement DataSource so that I have something like
InputStreamDataSource then  I can send some generated contents in my java
program as e-mail attachment?
