The service is expecting the string without the
<SCIncidentProcessing:query> element ... in other words, what you see as
"Input 2"
The stub that axis generated has the method with parameter of type
OMElement ( SCIncidentProcessing sCIncidentProcessing0), which is why I
had to create the OMElement input to pass into the method. It doesnt
allow me to just passing in a plain old String. But when I create the
OMElement, I had to do the following:
> OMFactory fac = OMAbstractFactory.getOMFactory();
> OMNamespace omNs = fac.createOMNamespace("http://namespace.com";,
> "namespace");
> OMElement input = fac.createOMElement("query",omNs);
> input.addChild(fac.createOMText(xmldata));
This adds the <SCIncidentProcessing:query> element to it. I couldnt find a
way to create the OMElement object with just the xmldata string. Is there
a way to create an OMElement without adding the
<SCIncidentProcessing:query> element to it?

Re: Web service not compatible with Axis?
Sorry to be obtuse ...
Does the service expect the message payload to be wrapped in the
<SCIncidentProcessing:query> element? Or is it simply expecting the
message payload? Why are you using a combination of the stub with the
OMElement?
Your code is telling AXIOM to create the <SCIncidentProcessing:query>
element and to embed the string inside it.
