[jira] [Commented] (ARIES-1140) Injected java.lang.reflect.Proxy implements only single interface

["Richard Ellis (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARIES-1140?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13846504#comment-13846504 ] 

Richard Ellis commented on ARIES-1140:
--------------------------------------

Does the generated interface org.talend.services.crmservice.CRMService extend javax.xml.ws.BindingProvider?
Section 121.7.11 of the Blueprint spec says that a service reference proxy must only support the methods of the given interface i.e. in this case the org.talend.services.crmservice.CRMService 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:
> <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>
> Where org.talend.services.crmservice.CRMService is generated jax-ws interface
> 2. Blueprint configuration importing service:
> <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>
> 3. Code in TestClass:
> ...
>     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);
>     }
> ...
> 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.
