javamail and attachments

pontovic

Hi

Im having a little problem re: Javamail and sending attachments. I know how to send an attachment when the source of the data is a file on the local filesystem, but how do I go about making an attachment if I want the file to be dynacmically created in memory instead and send to the use then ?

I have a method to create the file in temporary memory using a ByteArrayOutputStream(), so can anyone help me with how to attach this to the email ? I have looked on the net and the tutorials only seem to deal with handling attachments from files.

I know of FileDataSource and URLDataSource, but they arent much help.

Thanks in advance

Nope you create/get a different datasource.

Take your usual "create mail" example

http://www.jguru.com/faq/view.jsp?EID=30251

but instead of
DataSource source = new FileDataSource(fileAttachment);

use
DataSource source = new ByteArrayDataSource(byte[] data, String type);

as provided in your javamail/demo folder under ByteArrayDataSource.java, or by a few other vendors.

like org.apache.commons.mail.ByteArrayDataSource
at http://jakarta.apache.org/commons/
