Hi,
I think I've narrowed down the cause of a problem I'm having, but I'm
not sure what the solution is. . .any help would be *greatly*
appreciated.
I'm trying to consume a web service that has published a pretty simple
WSDL (attached). There's only one method exposed via the service, and
it's called "executeService" which takes a single argument (an XML
string).
I installed Axis2 v1.2 in my Java 1.4 environment and ran this command:
WSDL2Java -uri brms.wsdl -p com.foo.brms.serviceinterface -d xmlbeans -s
-o ..\java -R ..\resources
That created a bunch of xmlbean supporting classes and a
BRMSServiceStub.java. Here's how I'm using it:
ExecuteServiceDocument executeServiceDoc =
ExecuteServiceDocument.Factory.newInstance( );
ExecuteService executeService =
executeServiceDoc.addNewExecuteService( );
executeService.setArg0( . . . my Xml String here. . . );
myBrmsServiceStub.executeService( executeServiceDoc );
The NPE stack trace that gets thrown is shown below, but I think the
problem is that there is no namespace inserted into the surrounding xml
that the generated xmlbeans class (ExecuteService) wraps around my XML.
Just before the executeService( ) call is made, here is the message
content of the executeServiceDoc:
<?xml version='1.0' encoding='utf-8'?>
<soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";>
<soapenv:Body>
<executeService xmlns="http://endpoint.brmsservice/";> !!!!!
<arg0 xmlns="">
...my Xml String here. . .
</arg0>
</executeService>
</soapenv:Body>
</soapenv:Envelope>
Shouldn't the "<executeService" element look more like this?
<blah:executeService xmlns:blah="http://endpoint.brmsservice/";>
I suspect that is the problem, because down in the stack when the
doWriteDefaultNs is called, the default namespace is looked up from a
map that maps the empty-string found in the executeService element to a
null namespace value.
What did I do wrong?
Thanks in advance!
