----------------------------------------------

Have you investigated the java.io.ByteArrayOutputStream class?

There is an example using an ObjectOutputStream at http://www.exampledepot.com/egs/java.io/SerializeObj.html

> I'm using POI to create .xls files in memory that I want to send as e-mail attachments.
I now have to first save the created POI workbooks, then attach the files to the e-mail and
then have a mechanism to clean up the temporary files after the mail was sent. The POI HSSFWorkbook
has a method:
> write(java.io.OutputStream stream) 
> If this operation could write directly into the e-mail attachment, it would increase
performance and require a lot less overhead to manage the temporary files.
> I am sure there are plenty other examples of attachments being created as files in memory
that could be sent directly without having to create it as an actual file first.
