Returning attachments from a web service..

["I-Sampige, Srinivas" <sr...@Boeing.com>]

I was able to successfully return a "DataHandler" from my web service method and process it on the client side. 
	
This is what I used in the WSDD -
-------------------------------
  <typeMapping deserializer="org.apache.axis.encoding.ser.JAFDataHandlerDeserializerFactory" 
               encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" 
               qname="ns2:DataHandler" 
               serializer="org.apache.axis.encoding.ser.JAFDataHandlerSerializerFactory" 
               type="java:javax.activation.DataHandler" xmlns:ns2="urn:EchoAttachmentsService"/>
---------------

This is what I did on the client side -
----------------
          QName qnameAttachment = new QName("urn:Email", "DataHandler");
          call.registerTypeMapping(DataHandler.class, //Add serializer for attachment.
                                   qnameAttachment,
                                   JAFDataHandlerSerializerFactory.class,
                                   JAFDataHandlerDeserializerFactory.class);

          call.addParameter( "op1", XMLType.XSD_STRING, ParameterMode.IN);
          call.setReturnType(qnameAttachment);
          String[] array = new String[1];
          array[0] = "hello";
          DataHandler returnedDh = (DataHandler) call.invoke(array);
-----------------



	But, now, I want to return multiple DataHandlers from my method by putting them in a javax.mail.internet.Multipart. This is what I am attempting -

			public Multipart getAttachments()
			{
				  MultiPart    multiPart = new MimeMultipart();

				  MimeBodyPart mbp1 = new MimeBodyPart();
				  String message = "SUCCESS";
			      	  mbp1.setText(message,"us-ascii");

     				  MimeBodyPart mbp2 = new MimeBodyPart();
      				  mbp1.setDataHandler(dh);

      				  multiPart.addBodyPart(mbp1);
                                                  multiPart.addBodyPart(mbp2);

				  return multiPart
			}

QUESTIONS:
		1)	I am not able to figure out what the corresponding serializer/deserializer would be?
		2)    Is this the best way of having my web service return an attachement? I would like to return some message like "Here is the product you slected" along with a PDF product manual, a gif image of the product and perhaps a video clip.



Thanks
