-----------------------------------------
Hi guys,
It happens that in some cases the "axisOperation" field in the MessageContext
is null, which causes a NPE in getApplicablePolicy() when trying to get the
operation's name.
This occurred by me when trying to execute the "RahasSAMLTokenV1205Test" test
case from the rampart-integration module.
I examined it and found out that the request dispatcher could identify the
service (SecureService in this case), but could not identify the operation to
execute (issue).
The problem seems to be that the action mapping of the Rahas module for the
Issue operation is:
http://schemas.xmlsoap.org/ws/2005/02/trust/RST/Issue (see rahas module.xml)
while the action set on the client is:
http://docs.oasis-open.org/ws-sx/ws-trust/200512 (see
RahasSAMLTokenV1205Test#getRequestAction())
Since these are obviously different, the SOAPActionBasedDispatcher does not
find the operation to invoke and thus the MC's axisOperation remains null. It
is interesting that without this patch the test case runs successfully.
Nandana, do you have an idea why this happens?

> 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
