Attachments / MTOM

[TDean]

Hi,

I read that you support SwA attachments by casting WebServiceMessage to SoapMessage. Then operate on SoapMessage in the normal J2EE way. I guess I could create interceptors analogous to JAX-RPC handlers in J2EE. These handlers could operate on the SoapMessage while the implementation deals mainly with payload.

Also, I saw that you will support MTOM with JAXB2. Does that mean that the JAXB endpoint binding is the first to support MTOM and that the other supported data bindings will eventually have support as well.

Hopefully, you will have samples of how to manipulate MTOM attachments. Basically, you will have to give us a javax.activation.DataHandler for input attachments and we will have to give you a javax.activation.DataHandler for output attachments.

Thanks.

Also, I saw that you will support MTOM with JAXB2. Does that mean that the JAXB endpoint binding is the first to support MTOM and that the other supported data bindings will eventually have support as well.

That's the idea. I created an abstraction called MimeMarshaller, which can marshal a DataHandler or a byte[] to a MIME attachment.

Hopefully, you will have samples of how to manipulate MTOM attachments. Basically, you will have to give us a javax.activation.DataHandler for input attachments and we will have to give you a javax.activation.DataHandler for output attachments.

I'm not sure if I have time to create a sample, but at least you can look at the unit test code to see how it works.

Hello,

i have a web service that i want to return an attachment.
i use jaxb2 and spring-ws- rc1.

i try with 2 schemas:

first:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
        targetNamespace="http://www.qindel.com/padron"
        xmlns="http://www.qindel.com/padron"
        elementFormDefault="qualified"
        attributeFormDefault="unqualified">

  <xs:element name="RespuestaVolante" type="tipo_RespuestaVolante"/>

  ...

  <xs:complexType name="tipo_RespuestaVolante">
    <xs:sequence>
    <xs:element name="attfake" type="xs:base64Binary"/>
    </xs:sequence>
  </xs:complexType>

this generate a byte [] attfake.

the second

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
        targetNamespace="http://www.qindel.com/padron"
        xmlns="http://www.qindel.com/padron"
        xmlns:xmime="http://www.w3.org/2005/05/xmlmime">

  <xs:element name="RespuestaVolante" type="tipo_RespuestaVolante"/>
  ...
  <xs:complexType name="tipo_RespuestaVolante">
    <xs:sequence>
    <xs:element name="attfake" type="xs:base64Binary" xmime:expectedContentTypes="application/octet-stream"/>
    </xs:sequence>
  </xs:complexType>
</xs:schema>

this generate a DataHandler attfake.

In the two cases the web service works and returns the same:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"><SOAP-ENV:Header/><SOAP-ENV:Body><ns2:RespuestaVolante xmlns:ns2="http://www.qindel.com/padron"><ns2:attfake>Sk9ERVIhISE=</ns2:attfake></ns2:RespuestaVolante></SOAP-ENV:Body></SOAP-ENV:Envelope>

but not in an attachment!
how configure it for returns the byte in an attachment?

thanks in advance,
César.

I'll try and generate a sample that shows MTOM attachments soon.

[Arjen Poutsma]

I've created that sample. It's called 'mtom' (quite a fitting name ), and has a JAX-WS client, so it's pretty interoperable.

I came across a couple of bugs in the MTOM supports, so I fixed those as well. No wonder you couldn't make it work: sorry about that.

The sample will be includes in the RC2 release, to be performed later this week.

Hi, Arjen,

Thank you for your sample, it is very helpful. One more question, if change to AxiomSoapMessageFactory, what are the dependencies? Thanks.

[Arjen Poutsma]

My focus has been on doing SAAJ MTOM support, and so far I haven't had time to investigate Axiom's MTOM stuff. So, for now MTOM on Axiom might work, but I haven't tried it yet.

Hello again,

i think that i have mtom enable in web service , because log:

but my client doesn't work:

public class PadronMarshallClient extends WebServiceGatewaySupport {
  ...
  JAXBElement response = (JAXBElement)getWebServiceTemplate().marshalSendAndReceive(request);
  respuestaVolante = (TipoRespuestaVolante)response.getValue();
  byte []attfake = respuestaVolante.getAttfake();
  logger.info("attfake: " + new String(attfake));
  logger.info("attfake.length(): " + attfake.length);

the others elements of the response has values, but attfake not, is empty.

what's wrong with my client configuration?

thank in advance,

[Arjen Poutsma]

I think the client-side support for JAXB2 MTOM marshalling is not working well. Could you create a JIRA issue for this please?

[cesar]

hello,

JIRA issue:
http://opensource.atlassian.com/proj...browse/SWS-156

thanks.
