I am new to JavaMail. I am writing a provider for Lotus Domino. I compose a MimeMessage, then use the writeTo()
method. such Exception is thrown out:

			

			java.io.IOException: The system cannot find the path specified
			

			at java.io.FileInputStream.readBytes(Native Method)
			

			at java.io.FileInputStream.read(FileInputStream.java:161)
			

			at javax.activation.DataHandler.writeTo(DataHandler.java:289)
			

			at javax.mail.internet.MimeBodyPart.writeTo(MimeBodyPart.java:1089)
			

			...........
			

			at javax.mail.internet.MimeMessage.writeTo(MimeMessage.java:1503)
			

		

			

			DominoAttachment attachment = (DominoAttachment) attachments.get(i);
			

			bodyPart = new MimeBodyPart();
			

			InputStreamDataSource dataSource = new InputStreamDataSource(attachment.getInputStream(), "image/gif");
			

			bodyPart.setDataHandler(new DataHandler(dataSource));
			

			multipart.addBodyPart(bodyPart);
			

		

			

			public class InputStreamDataSource implements DataSource {
			

			private InputStream is = null;
			

			private String contentType = "";
			

			public InputStreamDataSource(InputStream is, String contentType) {
			

			this.is = is;
			

			this.contentType = contentType;
			

			}
			

			public String getName() {
			

			return "";
			

			}
			

			public String getContentType() {
			

			return contentType;
			

			}
			

			public InputStream getInputStream() {
			

			return is;
			

			}
			

			public OutputStream getOutputStream() {
			

			return System.out;
			

			}
			

			}
			

		

			

			I suppose that the data should be read from InputStreamDataSource.getInputStream()
			

			

			but In the Exception stack, It shows
			

			java.io.FileInputStream.read called
			

			

			what is the problem?? I am lost.
			

			Thanks a lot in advance.
