Hello
I need to update a facade to some web service proxy classes to a
third party web service, and expose them as a service. This for two reason : to maintain the same interface for all application that need to use the system : actually its migrating and there are a few differences in the
third party ws (method names); and to expose a simplified interface.
The
third party has provided me with a manual and some pregenerated proxy classes to their service (the java file says generated with axis2 1,4) . I've used netbeans 6.8 and the axis2 plugin to create an axis2 service . This service contains the proxy classes and the facade class which instantiate the web service proxy and calls its method; the facade class is exposed as service. I've used axis2 1.4 (at beginnig and later 1.5 ) and tomcat 6.0.
The first test i did was to call the facede methods from inside the project itself and it worked. Then i've created a new project with a jax-ws web service client to call my class deployed on axis2.
At this point has happened two strange thing :
In the axis2 services page has appeared the
third party proxy class as if it were a new service (if i try to get the wsdl axis raises an error ).
eg. the proxy interface is named WebServiceAPI (_stub is the concrete class) and , after the first call to my service , i find a new "WebServicesAPI1272968932531_1" service inside axis . The call obvoiusly fail
i've began to sniff soap messages with wireshark and i've found they differs when using proxy classes direclty from my facade test class by the messages created after being deployed on axis. i've noticed they differs for the presence of the soap header in the failing message.
any help would be greatly appreciated : maybe i messed up something, there might be some incompatibilities or version mistakes?
below i've added the signature of the
third party proxy, its impementation and the different soap messages:
