Axis2 Jaxb binding and MTOM issue
---------------------------------
Key: AXIS2-3612
URL: https://issues.apache.org/jira/browse/AXIS2-3612
Project: Axis 2.0 (Axis2)
Issue Type: Improvement
Components: databinding
Affects Versions: 1.3, 1.4
Reporter: Narayan Singh Dhillon
I tried a simple web service client with JAXB binding, and noticed that MTOM
parts are being in-lined in the soap message as opposed to being XOP
attachments.
The same client works fine with ADB binding.
Code example:
FileDataSource fileDataSource = new FileDataSource("C:\\upload.dat");
DataHandler fileDataHandler = new DataHandler(fileDataSource);
InitiateRequest request = new InitiateRequest();
request.setRequestId("xxxxx");
request.setSubmission(fileDataHandler);
request.setSignature(sigDataHandler);
Response:
--MIMEBoundaryurn_uuid_EAE9BC656EBBB536921205317613109
Content-Type: application/xop+xml; charset=UTF-8; type="text/xml"
Content-Transfer-Encoding: binary
Content-ID: <0.urn:uuid:[EMAIL PROTECTED]>
<?xml version='1.0' encoding='UTF-8'?>
<soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";>
<soapenv:Body>
<InitiateRequest xmlns="urn:uploadfile">
<requestId>xxxxx</requestId>
<submission>VGVzdCBQYWluIFN1Ym1pc3Npb24=</submission>
<signature>VGVzdCBzaWduYXR1cmU=</signatur>
</InitiateRequest>
</soapenv:Body>
</soapenv:Envelope>--MIMEBoundaryurn_uuid_EAE9BC656EBBB536921205317613109--0
There are different views on this:
<Ajith Ranabahu>
Perhaps this has to do with JAXB using the StAX interfaces to
read/write XML ? If you see the MTOM support in ADB you'll see we went
to great lengths to provide a way to carry over the binary blob to the
data binding framework without text conversions. We did this by
introducing a property value through the StAX readers getProperties
method (See [1] for details)
So unless the data binding framework would know about this behavior
then it is unlikely that they support optimal binary. AFAIK we have a
similar problem with XMLBeans

Narayan,
with jaxb you can supply your own data handlers for streaming. hopefully
someone on the team can help write a sample.
Please add an enhancement request for a sample in JIRA so we won't
forget.
thanks,
dims
