Using IMAP, how would you modify an existing 'message text' of a message in a folder, and copy the resulting message to another folder. The folders were open with READ_WRITE permission and only one session was opening them at a time.


To modify a message, When I do
Message message[] = folder.getMessage();
Message m = folder.getMessage(1);
m.setText("dfjfhsfshdfljdss");



I am always getting


javax.mail.IllegalWriteException: IMAPMessage is read-only
at com.sun.mail.imap.IMAPMessage.setDataHandler(IMAPMessage.java:519)
at javax.mail.internet.MimeMessage.setContent(MimeMessage.java:1300)
at javax.mail.internet.MimeBodyPart.setText(MimeBodyPart.java:817)
at javax.mail.internet.MimeMessage.setText(MimeMessage.java:1333)
at javax.mail.internet.MimeMessage.setText(MimeMessage.java:1321)




I think the message cannot be changed, since it might be read only by design. Is copying all the properties of the message, and recreating in the destination folder the only solution.

Any code snippets might help.
