XMLBeans, Axiom, and Synapse/WSO2-ESB
I'm trying to see if I can use XMLBeans to deal with an Axiom SOAPBody. The
following DeveloperWorks guide showed how to bring Axiom and XMLBeans
together:
http://www.ibm.com/developerworks/library/x-axiom/
So I tried to extend Sample 380 in WSO2-ESB and basically had this as the
first lines in my mediate() function:
XMLStreamReader reader =
mc.getEnvelope().getBody().getFirstElement().getFirstElement().getXMLStreamReaderWithoutCaching();
GetQuoteResponse resp = GetQuoteResponse.Factory.parse(reader);
System.out.println("Validate " + resp.validate());
System.out.println(resp.toString());
This is what prints out
Validate false

<ns:symbol>IBM</ns:symbol>
<ns:volume>5034</ns:volume>
</ns:return>
I believe the problem is because the return element is defined as having a
type of samples.services.GetQuoteResponse. How do I get XMLBeans to accept
the return element so that I can perform a function such as resp.getLast()?
Am I completely off base? Is there a better way to do this?
Thanks,
Michael

Radu,
mc is the MessageContext class from Apache Synapse
http://synapse.apache.org/apidocs/org/apache/synapse/MessageContext.html.
I'll try your debug steps to see if I can get any more information.

Mike,
What is "mc"? What Java class/API?
I think you can do two things to debug this further:
1. Use XmlOptions.setErrorListener(Collection) to retrieve the error messages, then see what the specific error is (use the XmlOptions object as parameter to the resp.validate() call)
2. Capture the XML passed from the SOAP body to XMLBeans (before it gets to XMLBeans). Save it to a file and see if it looks ok (based on its Schema) and where the discrepancy is. I am thinking there are maybe some namespace bindings that don't make it across from the SOAP stack to XMLBeans, it's a possibility.
