Message disposition

[Goran Markovic]

Hi. I have a problem when I want to retrieve a disposition of message.
Previously I created a message, add attachment to is, and invoke :

     message.setDisposition(Part.ATTACHMENT); 

The message successfully goes into my INBOX. But when I try to retrieve a messages attributes like in this code

// Here's the attributes...
	System.out.println("This message is approximately "
	+ messages[i].getSize( ) + " bytes long.");
	System.out.println("This message has approximately "
	+ messages[i].getLineCount( ) + " lines.");
	String disposition = messages[i].getDisposition();
	if (disposition == null) ; // do nothing
	else if (disposition.equals(Part.INLINE)) {
	System.out.println("This part should be displayed inline");
	}
	else if (disposition.equals(Part.ATTACHMENT)) {
	System.out.println("This part is an attachment");
	String fileName = messages[i].getFileName( );
	if (fileName != null) {
	System.out.println("The file name of this attachment is "
	+ fileName);
	}
	}

It appears that message.getDisposition() returns null. Why is that???
