Using JavaMail1.2 i was able to send images as attachments,but when i try to retrieve them i get an error.I send the images as FileDataSource object to a multipart message.It worked.
I then tried to read a multipart message and tried to display mime type "image/..." in a JTextPane.
But when i tried to read the mail and use a similar FileDataSource object,as i used to send i get a Class Cast Exception:

java.lang.ClassCastException: javax.mail.internet.MimePartDataSource at JavaMailer.listParts(JavaMailer.java:692)
at JavaMailer.checkMime(JavaMailer.java:664)
at JavaMailer.readMail(JavaMailer.java:624)
at JavaMailer$7.mouseClicked(JavaMailer.java:249)
at ......

When i changed the FileDataSource to MimePartDataSource, the getName() method returns null, thereby JTextPane showing blank.
i read in JavaMail API1.2 that getName() returns nothing for MimePartDataSource implementation.

Then, how can i get the filename of the "image/..." part of a multipart
message?
