Subject RES: AW: How do you pass an XML document between Axis and .Net Cl ient?
Date Fri, 31 May 2002 15:04:14 GMT
Hi Everybody!

I'd like to know if it's possible to pass a .VRML or .JPG documents too.
Have you had this experience!?

Thank's a lot,

Ack!

Maybe this shouldn't bug me since the whole point of Axis is you're not 
supposed to care what's on the wire--but the notion of XML-encoding an 
entire XML document so it can be passed as a string via RPC, when
instead 
you could just insert the literal document as the SOAP Body, makes no
sense 
to me.

You could have this:

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope 
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <SOAP-ENV:Body>
<my_xml_document><blah/><blah/></my_xml_document>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

or you could have this:

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope 
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <SOAP-ENV:Body>
<ns1:someParameter xmlns:ns1 = "urn:some_namespace" 
xsi:type="xsd:string">&lt;my_xml_document>&lt;blah/>&lt;blah/>&lt;/my_xm
l_document></someParameter>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

The longer your XML document, and the more entities that need to be 
escaped, the more convoluted the second version gets.  Like I say, maybe
I 
just shouldn't care--but what is doc style for if not situations like
this?

Sorry if I've overlooked something obvious here.  I'm new to all this,
and 
maybe I've misunderstood the problem or the proposed solution.  Anyway,
if 
you want an example messaging service, check out the message/ directory
in 
the samples that came with Axis.  You can see it creating
SOAPBodyElements 
from DOM Elements, which is what you want to do.  Your messaging client 
would need to grab the document element from your DOM (with the 
Document.getDocumentElement() call) and pass that to the SOAPBodyElement

constructor.  Pass this single SOAPBodyElement to your service, and what

the service will get is a SOAP Envelope with your XML document for the
body.
