Subject [jira] Resolved: (AXIS2-3032) Anonymous WS operation invocation
Date Wed, 01 Aug 2007 11:08:53 GMT


Deepal Jayasinghe resolved AXIS2-3032.

    Resolution: Won't Fix

> Anonymous WS operation invocation
> ---------------------------------
>                 Key: AXIS2-3032
>                 URL:
>             Project: Axis 2.0 (Axis2)
>          Issue Type: Bug
>          Components: kernel
>    Affects Versions: 1.2
>            Reporter: Severin Ecker
>            Priority: Minor
> I'm not 100% positive that this really is a bug, but since i got no reply neither in
the users nor in the developers list i'm filing it here to raise attention.
> I have a webservice (using axis2 to handle the soap stuff) and I wanted to use this service
with both, WSDL-based access (i was using SOAPui for this) and anonymous operation invocation
(with the ServiceClient.sendReceive(OMElement elem) method).
> Using WSDL base access everything works as intended (e.g.: using the following SOAP envelope)
> <soap:Envelope
>    xmlns:soap=""
>    xmlns:ns="">
>    <soap:Header/>
>    <soap:Body>
>      <ns:GetCapabilitiesRequest/>
>    </soap:Body>
> </soap:Envelope>
> At service implementation site within the method getCapabilities(OMElement e); (<--
this is the invoked method)
> the parameter e is
> <ns:GetCapabilitiesRequest/>
> So far so good.
> Now when trying to access anonymously I have to encode the operation somewhere so I have
the following envelope
> <soap:Envelope
>    xmlns:soap=""
>    xmlns:ns="">
>    <soap:Header/>
>    <soap:Body>
>      <ns:getCapabilities>
>        <in0>
>          <ns:GetCapabilitiesRequest/>
>        </in0>
>      </ns:getCapabilities>
>    </soap:Body>
> </soap:Envelope>
> The request gets resolved correcty by axis (using the
> SOAPMessageBodyBasedDispatcher) BUT here's the catch. Suddenly the parameter which the
(correct!) service operation gets is
> <ns:getCapabilities>
>   <in0>
>     <ns:GetCapabilitiesRequest/>
>   </in0>
> </ns:getCapabilities>
> This is rather useless because in that case the service operation must be ready to handle
all kinds of different parameters depending on the invocation method used!? Shouldn't the
SOAPMessageBodyBasedDispatcher remove the 'meta-informational' stuff (in this case the getCapabilities
(aka operation-name), and in0 (parameter direction)) and only send the real parameter to the
> If I'm mistaken, how can I invoke an operation anonymously and does not have the problem
of ending up with wrong parameters on the service side?
