If you're using WS-Policy, CXF can automatically set up WS-Addressing for you if you use the <Addressing> policy expression.
Decoupled responses
By default, WS-Addressing using anonymous Reply-To addresses. This means the request/response patterns are synchronous in nature and the response is sent back via the normal reply channel. However, WS-Addressing allows for a decoupled endpoint to be used for receiving the response and CXF will then correlate it with the appropriate request. There are a few ways for configuring the address on which CXF will listen for decoupled WS-Addressing responses.
HTTP Conduit configuration
The HTTP Conduit's client configuration has an option for a DecoupledEndpoint address. If the conduit has this configured, all requests sent via that conduit that have WS-Addressing enabled will have their responses sent to that endpoint:
Code Block | ||||
---|---|---|---|---|
| ||||
<http:conduit name="{http://apache.org/hello_world_soap_http}SoapPort.http-conduit">
<http:client DecoupledEndpoint="http://localhost:9090/decoupled_endpoint"/>
</http:conduit>
|
Request Property
The address can be set via a Request Context property.
Code Block | ||||
---|---|---|---|---|
| ||||
((BindingProvider)proxy).getRequestContext()
.put("org.apache.cxf.ws.addressing.replyto", "http://localhost:9090/decoupled_endpoint");
|
AddressingProperties
The CXF org.apache.cxf.ws.addressing.impl.AddressingPropertiesImpl object can be used to control many aspects of WS-Addressing including the Reply-To:
Code Block | ||||
---|---|---|---|---|
| ||||
AddressingProperties maps = new AddressingPropertiesImpl();
EndpointReferenceType ref = new EndpointReferenceType();
AttributedURIType add = new AttributedURIType();
add.setValue("http://localhost:9090/decoupled_endpoint");
ref.setAddress(add);
maps.setReplyTo(ref);
maps.setFaultTo(ref);
((BindingProvider)port).getRequestContext()
.put("javax.xml.ws.addressing.context", maps);
