Problem to retrieve the effective policy from MessageContext when we have
policy attachment at binding level
------------------------------------------------------------------------------------------------------------
Key: AXIS2-4114
URL: https://issues.apache.org/jira/browse/AXIS2-4114
Project: Axis 2.0 (Axis2)
Issue Type: Bug
Components: kernel
Reporter: Dobri Kitipov
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
