--------------------------------------
Summary: Injected java.lang.reflect.Proxy implements only single
interface
Key: ARIES-1140

Project: Aries
Issue Type: Improvement
Components: Proxy
Affects Versions: proxy-impl-1.0.1
Reporter: Andrei Shakirin
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.
