Richard Ellis commented on ARIES-1140:
--------------------------------------
No problem Andrei. I now understand that the CRMService is just business logic
so it is clear it doesn't make sense to add the binding provider interface
there as well.
I hope there is a solution in cxf. Maybe the BindingProvider can be determined
from just the injected interface name because I think Christian is right that
the blueprint proxy of the cxf proxy does not have a lot of information.
> Injected java.lang.reflect.Proxy implements only single interface

> Hi,
> I have a problem in using Blueprint together with CXF and Karaf projects. The
> use case is quite trivial: I inject OSGi service into java class source. This
> OSGi service is exposed by declared jax-ws client.
> 1. Blueprint configuration exporting service:
> {code:xml}
> <blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0";
> xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
> xmlns:cxf="http://cxf.apache.org/blueprint/core";
> xmlns:jaxws="http://cxf.apache.org/blueprint/jaxws";
> xsi:schemaLocation="http://www.osgi.org/xmlns/blueprint/v1.0.0
> http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd
> http://cxf.apache.org/blueprint/jaxws
> http://cxf.apache.org/schemas/blueprint/jaxws.xsd
> http://cxf.apache.org/blueprint/core
> http://cxf.apache.org/schemas/blueprint/core.xsd
> ">
> <jaxws:client id="crmClient"
> xmlns:serviceNamespace="http://services.talend.org/CRMService";
> serviceClass="org.talend.services.crmservice.CRMService"
> serviceName="serviceNamespace:CRMServiceProvider"
> endpointName="serviceNamespace:CRMServicePort"
> address="http://localhost:8080/service/CRMService"/>
> <service ref="crmClient"
> interface="org.talend.services.crmservice.CRMService" />
> </blueprint>
> {code}
> Where org.talend.services.crmservice.CRMService is generated jax-ws interface
> 2. Blueprint configuration importing service:
> {code:xml}
> <blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0";
> xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
> xsi:schemaLocation="http://www.osgi.org/xmlns/blueprint/v1.0.0
> http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd";>
> <reference id="CRMServiceClient"
> interface="org.talend.services.crmservice.CRMService" />
> <bean id="TestClass"
> class="org.talend..demo.TestClass">
> <property name="crms" ref="CRMServiceClient" />
> </bean>
> </blueprint>
> {code}
> 3. Code in TestClass:
> {code:java}
> ...
> private CRMService crms;
> public void setCrms(CRMService crms) {
> this.crms = crms;
> System.out.println(crms.getClass());
> System.out.println(crms.toString());
> System.out.println(crms instanceof BindingProvider);
> }
> ...
> {code}
> Problem:
> The problem is that crms proxy, injected into TestClass, implements only
> org.talend.services.crmservice.CRMService.
> The proxy calls methods of org.apache.cxf.jaxws.JaxWsClientProxy which
> implements javax.xml.ws.BindingProvider interface. I expect that crms proxy
> also implements javax.xml.ws.BindingProvider, but it is not the case. I have
> the following output from setCrms:
> class com.sun.proxy.$Proxy151
> org.apache.cxf.jaxws.JaxWsClientProxy@c3f8b42
> false
> The proxy calls toString() method of JaxWsClientProxy, but it is not instance
> of BindingProvider interface. The problem is that this proxy is not jax-ws
> compatible, because spec requires that all proxies implementing
> BindingProvider interface.
> Interesting that Spring DM proxy hasn't such problem: it implements
> BindingProvider interface in this scenario.
> Is it Blueprint problem? (seems to be true for me)
> Is there way to fix this in Blueprint?
> Regards,
> Andrei.
