Thanks for your reply. The service provider does provide a description of
the expected string format. It expects a string of XML much like the one
I have shown below.
The header Axis appends to the object sent to the web service seems to be
the cause of the exception. Below is my code invoking the method using
Axis and displaying the inputs using toString() and getText()
SCIncidentWebServiceStub stub = new SCIncidentWebServiceStub();
OMFactory fac = OMAbstractFactory.getOMFactory();
OMNamespace omNs = fac.createOMNamespace("http://namespace.com";,
"namespace");
OMElement input = fac.createOMElement("query",omNs);
input.addChild(fac.createOMText(xmldata));
System.out.println("Input1");
System.out.println(input.toString());
System.out.println("Input2");
System.out.println(input.getText());
OMElement output = stub.SCIncidentProcessing(input);
This is what is shown in the console:
Input1
<SCIncidentProcessing:query
xmlns:SCIncidentProcessing="http://namespace.com";><?xml version='1.0'
encoding='utf-8' standalone='yes'?><SCIncidentWebService
action='query'><setup><webserviceUser>User1</webserviceUser><webserviceUserPassword>testPassword01</webserviceUserPassword><eventUser>ABC123lt;/eventUser></setup><incident><incidentNumber>10697040</incidentNumber><workHistory><workHistoryType>All</workHistoryType></workHistory></incident></SCIncidentWebService></SCIncidentProcessing:query>
Input2
<?xml version='1.0' encoding='utf-8'
standalone='yes'?><SCIncidentWebService
action='query'><setup><webserviceUser>User1</webserviceUser><webserviceUserPassword>testPassword01</webserviceUserPassword><eventUser>ABC123</eventUser></setup><incident><incidentNumber>10697040</incidentNumber><workHistory><workHistoryType>All</workHistoryType></workHistory></incident></SCIncidentWebService>
I have used Eclipse generated web service client stubs to invoke this web
service successfully. This is because the Eclipse generated stubs provide
the method SCIncidentProcessing(String inputString) rather than
theSCIncidentProcessing(OMElement sCIncidentProcessing0) method that Axis
generated stubs provide.
When I invoke the web service using the Eclipse generated client stubs
instead of Axis (with the input string like "Input 2" above, I get no
exceptions and I get correct results back from the web service But with
Axis, I get the exception that I mentioned before. So it seems like to me
that the webservice is doing a toString() instead of a getText() on the
input before doing any processing. Could this mean that the particular
web service I am trying to use is not compatible with Axis?

Re: Web service not compatible with Axis?
Why does the service exchange strings rather than typed XML? If it's a
web service, it should define its interface using a
language-independent API, such as WSDL or a schema. Did the service
provider at least provide you with a description of the expected
string format? The first place I'd look is at the input message. My
guess is that it isn't formatted properly.
