> I've got the following exception when SCR starts my component:
> 2010-05-05 15:00:58,389 : LoggerService.log : [org.ow2.easybeans.proxy.factory.RemoteCallFactory]
Cannot register Component
> org.osgi.service.component.ComponentException: The component name 'org.ow2.easybeans.proxy.factory.RemoteCallFactory'
has already been registered.
> 	at org.apache.felix.scr.impl.ComponentRegistry.registerComponent(ComponentRegistry.java:291)
> 	at org.apache.felix.scr.impl.BundleComponentActivator.loadDescriptor(BundleComponentActivator.java:247)
> 	at org.apache.felix.scr.impl.BundleComponentActivator.initialize(BundleComponentActivator.java:147)
> My XML declaration files is the following:
> <component xmlns="http://www.osgi.org/xmlns/scr/v1.1.0">
>   <implementation class="org.ow2.easybeans.proxy.factory.RemoteCallFactory" />
>   <service>
>     <provide interface="javax.naming.spi.ObjectFactory" />
>     <provide interface="org.ow2.easybeans.proxy.factory.RemoteCallFactory" />
>   </service>
> </component>
> As you can see, there is no 'name' attribute (The spec says that by default the implementation
classname is used).
> I'm sure that the component is not present in 2 bundles, so the default name should be
unique.
> As a workaround, if I set the 'name' attribute, everything works well, but as the XML
schema (and the spec) says that it is optional, I think that SCR should support that use case.
