NullPointerException w/static WSDL, same WSDL works when generated on the fly
I'm getting an interesting error when deploying a web service using a
static WSDL (the static WSDL I'm using is actually a copy of a CXF
dynamically generated WSDL which works, this error only occurs when I
use this same WSDL in a static manner via the wsdlLocation @WebService
annotation attribute).
Here is the exception reported on the server when executing the service
from a client w/the payload:
Payload: <soap:Envelope

--------------------------------------
Debugging and digging into the code reveals that when AbstractInvoker
heads into MethodDispatcher's getMethod() to retrieve the Method, a null
is returned. Further debugging shows that JAXWSMethodDispatcher is the
actual implementation of MethodDispatcher being used which itself
extends SimpleMethodDispatcher, in SimpleMethodDispatcher an internal
Map is maintained of available methods, opToMethod.
The debugger shows my single sendEmail() method being contained in the
opToMethod map, however when the SimpleMethodDispatcher.getMethod()
looks for it by the OperationInfo reference passed in (which reports an
identical toString() value to the map key entry) a null is returned
which is of course is propagated up, not checked, eventually referenced,
finally resulting in the NullPointerException. The problem -- as I see
it -- is on the Map lookup which is done by hashCode(), the hashCode()
contained in the stored map key and the inbound OperationInfo object are
different, hence Map.get() returns null. If I switch this same service
back to a dynamic WSDL then the same debugging results in the same
hashCode() between the two OperationInfo objects.
So I've done all this digging and I just know this has to be something
simple, any thoughts???
