Hi Simon
According to the spec,line 1358 to 1360 define the reference interface
restriction.
1358 If an interface is specified it must provide an interface which is the
same or which is a
1359 compatible superset of the interface declared by the promoted component
reference, i.e. provide
1360 a superset of the operations defined by the component for the reference.
I think the interface only need to compare the operation is compatible or not.
My understanding about 'namespace' is that if the interface is compatible ,the
package name of java interface must be consistent to the target namespace of
wsdl interface,is my understanding right?

> See TUSCANY-2033 for the background to this problem.
> When a component reference defined with <interface.java> (either explicitly
> or implicitly by introspection) is promoted to a composite reference defined
> with <interface.wsdl>, and there is a namespace conflict between the
> component reference's <interface.java> and the composite reference's
> <interface.wsdl>. this conflict should be diagnosed as an error because it
> violates the spec rule that an interface specified on a composite reference
> must be a compatible superset of the interface of the promoted component
> reference. In this case, the composite interface is incompatible with the
> component reference because it has a different namespace.
> There is code in CompositeWireBuilderImpl.connectCompositeReferences() to
> handle connections between composite references and promoted compoennt
> references. The only interface processing performed in this method is to copy
> the component reference's interface contract to the composite reference's
> interface contract if the composite reference does not have an interface
> contract. Code should be added here to check for conflicts between the
> composite reference's interface and the component reference's interface if
> both interfaces are specified.
> Similar code should be added to
> CompositeWireBuilderImpl.connectCompositeServices() to check that the
> composite service interface is a compatible subset of the component service
> interface as required by the spec.
