Paul/Anyone,
You mentioned earlier in this thread the use of @ResourceContext to get
managed sub-resources:
>> It is possible to inject information into sub-resources using
>> the ResourceContext class.
>>
>> @Path("{id}/branch")
>> public BranchResource getBranchResource(@Context ResourceContext

>> }
Is the above code correct? Shouldn't the line in the body be:
ScopedBranchResource sbr = rc.getReource(BranchResource.class);
My other question is that the @Path has a param {id}. In my case, I'm
passing the bound id value to the constructor of my subresource. Is
this possible?
@Path("{key}")
public NodeResource getNodeResource(@PathParam("key") String
key) {
return new NodeV1Resource(key, nodeRemote);
}
The nodeRemote variable is a local variable in the parent resource class
that is a remote interface to an EJB that I'm presently passing to the
subresource because it is need to process operations on Node instances.
How would the above method be constructed using the @Context
ResourceContext rx?
