Christian Schneider commented on ARIES-1140:
--------------------------------------------
I guess it is because of the proxy Richard mentioned. The proxy has to be built
once and possibly before the first service is bound. So the proxy can not rely
on the interfaces available on the actual service object. It can only know
about the interfaces defined on the service reference. It might work if we
would allow to define more than one interface for a reference. This would be
outside the spec though.
> 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.
