I'm trying to get a handle on a policy problem where I get a NPE in the Axis
runtime. The NPE is caused because Axis is failing to find a named
operation. It's looking for an operation of the form
{http://helloworld}getGreetings
but failing as the operation is registered in the binding inside the Axis
service model with the name
{
http://helloworld/HelloWorldServiceComponent/$promoted$HelloWorldService}getGreetings
This seems to come back to how we generate WSDL. The generated WSDL inside
the WS Binding in this case imports the real WSDL that was specified in an
interface.wsdl statement. The generated WSDL [1] is given the target
namespace {
http://helloworld/HelloWorldServiceComponent/$promoted$HelloWorldService}
while the original WSDL retains the target namespace {http://helloworld}.
Axis is getting confused when it pulls binding and porty type information
from different parts of the WSDL definition. In this case, for example,
there is an operation defined in the binding
{
http://helloworld/HelloWorldServiceComponent/$promoted$HelloWorldService}getGreetings
Which has a different QName to that defined in the original port type
{http://helloworld}getGreetings
Anyone know why we generate a targetNamespace for this wrapper WSDL which
takes the original namespace and adds the service name to the end of it?
