SOAP multi-part responses

I'm using the oxf:delegation processor to successfully make rpc SOAP calls.

However, the resulting data output from the delegation processor only seems to contain the <response> part of the SOAP envelope.

I have cases where the <response> identifies hrefs to pick up data from the rest of the SOAP envelope, eg
<response>
   <item href="#id0"/>
   <item href="#id1"/>
</response>

How do I get this data, which should be in part of the SOAP envelope identified something like
<multiref id="id0" ...>some data</multiref>
<multiref id="id1" ...> some more data</multiref>

Answered my own question...  For anyone who's interested:

Include a select attribute on the operation element in the
oxf:delegation processor
Set the value of the select attribute to be "/" to return the complete
SOAP envelope (or any other XPATH expression depending what you want to
be returned).

In my case this now means parsing the <response> part to pick up the
href IDs, and then getting the other parts of the document based on
these.

Steve,

I've just encountered the same multiRef issue. The web services I'm  
working on responds with the following pattern:

<soap:body>
     <response>
         <item href="x"/>
          <item href="xx"/>
     </response>
     <multiRef id="x"/>
     <multiRef id="xx"/>
</soap:body>

By default (when operation/@select not specified), OPS delegation  
returns everything after <soap:body> which in this case not a well-
formed XML. I didn't get any response at all, except the 'could not  
be added to the branch "null" ' error message.

So thank you for this tips. I think the use of the "select" attribute  
should be shown in the code example in the documentation.


Regards,

Boon

That's exactly the pattern that my web service is responding with for
one of the calls; wonder if we are using the same one?

I found the most flexible approach was to select the whole of the SOAP
envelope, and have some XSLT post-processing in my pipeline to return
the parts I need depending on the call that I'm making; controlling the
whole lot with an XML API configuration file.

"Optionally you can declare what part of the SOAP result document is
returned by specifying an XPath expression in the optional select
attribute on the operation element. If you don't specify an expression,
by default when the style is RPC the content of the first child element
under the SOAP body is returned, and when the style is document the
content of the SOAP body is returned."

Hi,

I am new to Axis2\c.

I am trying to get the multiref values from the response. But I am not able to do so. I tried "select" attribute option but not able to get the full Envelop response. If anybody has used this attributes, please let me know.

I used TCPMon to check the packets. I found that the <soapenv:Body> contains operation response and also multiref values.

Please help me to know, how to access the multiRef values.

Thanks,
Vishal

Hi Vishal

I've previously processed SOAP multi-part responses by setting the select
attribute to "/", and using some xslt to process the resulting response.

I'd recommend soapUI http://www.soapui.org/ as an excellent tool for
debugging - you can see the request and response using this tool, and once
you can see the XML response you'll probably have a better idea for how to
process it.

I believe the select attribute will work fine, you'll just need the correct
xpath to get the part of the envelope you want, but be careful to specify
namespaces for any namespace prefixes that you use.

Regards
Steve

H Vishal,

I used the select attribute to open and discard, as it were,
the envelope, and deliver a document with just the multiref
elements:  select="//multiRef"

the whole step:

    <p:processor name="oxf:delegation">
         <p:input name="interface">
             <config>
                 <service id="StandardService" type="webservice"
                     endpoint="http://www.nacse.org/neesSiteSpecs/ 
services/StandardService">
                     <operation nsuri="http://service.ssdb.nacse.org"  
name="getEquipmentByID"
                         encodingStyle="http://schemas.xmlsoap.org/ 
soap/encoding/"
                                select="//multiRef"/> <!-- Select / when testing -->
                 </service>
             </config>
         </p:input>
         <p:input name="data"><dummy/></p:input>
         <p:input name="call" href="#call-1"/>
         <p:output name="data" id="ssdb-1"/>
     </p:processor>

Cheers,
Hank
