Attachment problems

[BTInternet <mg...@btinternet.com>]

I am trying to create a soap message with attachments and running into a
problem I cannot figure out.  Below is a fragment of code used to add an
attachment to a SOAP message.  It throws a nullPointer Exception in the
createAttachmentPart method.  Any ideas?

	URL report = new File(filePath).toURL();
	DataHandler dataHandler = new DataHandler(report);
	System.out.println(dataHandler.getContentType());
// Exception thrown at this point		
	AttachmentPart attachment =
message.createAttachmentPart(dataHandler);
	System.out.println(attachment.getContentType());
	attachment.setContentId("report_id");
	message.addAttachmentPart(attachment);

Thanks

Martin
