streams in javamail

[Karthik Iyer]

Hi
I was using an SMTP mail program along with an UUEncoder class, that made it possible to pass a HTML formatted string as a parameter. This string will be converted into a html page and sent as an attachment with the email. However when i migrated to JavaMail, i found that the only way to send an attachment was if we had the file physically present in a folder (FileDataSource accepts a file name or a file object as a parameter).
Is there anyway that i can circumvent this and send a string as an attachment by writing it into a stream or something, so that the creation of the physical file in a folder can be avoided.
Thanks
