Question

Hi,
I am trying to send an attachment using Saaj API. As soon as I use the attaachment object and attach it to message I get an exception . If I remove it the over all webservice communication works successfully. Even if I set the content type in the mimeheader explicetely it gives the same error. Any Suggestion how what could be wrong here or how can I fix it please ?

Below is what the program looks like .
public static void main(String[] args) {
          String nameSpace = "ns";

                    String username = "BLAH";
                    String password = "****";
                    String authorization = new sun.misc.BASE64Encoder().encode((username+":"+password).getBytes());
                    MimeHeaders hd = soapMessage.getMimeHeaders();
                    hd.removeAllHeaders();
                    hd.addHeader("Authorization", "Basic " + authorization);

                    // creat a SOAP part have populate the envelope

                    soapMessage.addAttachmentPart(attachmentPart);
                    // set the saves into the structure

                    soapConnection.close();
          } catch (Exception ex) {

I suppose I should also include the bit where the Servlet actually SENDs the resulting SOAPMessage
SOAPMessage msg = ProcessXML.buildXML(outMessage);
// try to send it
try {
     response.setContentType("text/xml");
     msg.writeTo(response.getOutputStream());
