Subject [jira] Commented: (AXIS2-4114) Problem to retrieve the effective policy from MessageContext when we have policy attachment at binding level
Date Wed, 10 Dec 2008 15:16:44 GMT

    [ https://issues.apache.org/jira/browse/AXIS2-4114?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12655239#action_12655239

---------------------------------------------------

Hi Detelin, 
        I debugged this issue in the Rampart build and it is not the AxisOperation which is
null but the bindingOperation. But your point is right, I think this dispatched using body
based dispatching as actions are obviously different. Fixed the findBindingMessage not to
cause NPE. 

thanks,
nandana

> Hi,
> I have a problem when I try to get the effective policy from a MessageContext when I
have a policy attached at the binding level of a Web Service. I am using Axis2 1.4.0
> Let me explain a little bit the scenario I have. I am using an AAR that has into its
services.xml:
> <parameter name="useOriginalwsdl">true</parameter>
> and a PolicyAttachment at its service level:
> <wsp:PolicyAttachment xmlns:wsp="http://schemas.xmlsoap.org/ws/2004/09/policy">
>             <wsp:AppliesTo>
>                 <policy-subject identifier="binding:soap11"/>
>                 <policy-subject identifier="binding:soap12"/>
>             </wsp:AppliesTo>
>             <wsp:Policy wsu:Id="User" xmlns:wsp="http://schemas.xmlsoap.org/ws/2004/09/policy"
xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">...
> </wsp:PolicyAttachment>
> As a result the WSDL generated has the policy specified and policy reference at the binding
subject level. Here is an excerpt from the wsdl for the SOAP11Binding:
> <wsdl:binding name="MTOMServiceSOAP11Binding" type="tns:MTOMServicePortType">
> <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
> <wsp:PolicyReference URI="#User"/>
> At client side I have a dynamic client. So the issue is that when I invoke the service
and the WSDL is read and the corresponding AxisService object is crated at the client side
I have some modules' handlers that take palce. One of them is a custom one in which I have
the following invocation:
> Policy policy = msgCtx.getEffectivePolicy();
> The problem is that this returns "null"! I debugged this and it came out that msgCtx
is not null. When the method is invoked it tries to calculate the effective policy as given
below.
>          AxisBindingMessage bindingMessage =
>              (AxisBindingMessage)
>  getProperty(Constants.AXIS_BINDING_MESSAGE);
>          if (bindingMessage != null) {
>              return bindingMessage.getEffectivePolicy();
>          } else {
>              if (axisMessage != null) {
>                  return axisMessage.getEffectivePolicy();
>              } else {
>                  return null;
>              }
>          }
> where bindingMessage  is null and axisMessage.getEffectivePolicy(); returns null, too.
When I dig through the AxisService -> AxisEndpoint -> AxisBinding -> here the PolicySubject
is in fact a PolicyReference to the Policy that is set into the AxisService policyMap. So
as a result axisMessage.getEffectivePolicy() returns null and I can not get the Policy I need.
> I saw that I need something like the AxisDescription.getApplicablePolicy in order to
locate the real Policy of a given PolicyReference.
> You can see the patch applied that I have tested and seem to me that works fine.
> Thank you in advance,
> Dobri
