Problem with attachment saving to db

Question

Hi,
I've encountered the following problem when writing a small app. to receive e-mails and subsequently storing them in a database.
  private  void handlePart(Part part) throws IOException, MessagingException {
         String disposition = part.getDisposition();
         if (disposition == null) { //body
            // do something dull
         } else if (disposition.equalsIgnoreCase(Part.ATTACHMENT)) {
              try {
                 saveAttachmentToDB(part.getFileName(), part.getInputStream(), part.getSize());
             } catch (SQLException e) {
                 System.err.print("SQL Error: ");
                 System.err.println(e.getMessage());
                 System.exit(-1);
         } else if (disposition.equalsIgnoreCase(Part.INLINE) && part.getSize()>9) {
           // do something to store to db 
     }and
public void saveAttachmentToDB(String filename, InputStream input, int size)
      throws IOException, SQLException {
        PreparedStatement pstmt;
        String Query = "insert Attachment VALUES(?,?)";
        pstmt = con.prepareStatement(Query);
        pstmt.setString(1, filename);
        pstmt.setBinaryStream(2, input, size); //method to insert a stream of bytes
        pstmt.executeUpdate();
      }Now the problem is that upon exection the system hangs on the first insert.
Probably this is because the size aint right...
I've tried it using different attachments, like MS Word documents, plain textfiles. Is this the way to do this?
Or must I use a DataHandler object, but if the latter is true can someone pinpoint me to a good tutorial on datahandlers.
I rewrote the former code using a part.WriteTo() writing to a ByteArrayOutPutstream --> converting that stream to a ByteArrayInputStream and calling setBinaryStream on that using the size of ByteArrayOutputStream.
If I did this the system wouldn't hang but it wrote the contentHeader and the body to the database. The body would than be in Base64 format, wich is not what I want... Please can somebody set me on the right track here?
Grts
