Re: Questions about feed-aggregator sample

[Willis C White <wh...@us.ibm.com>]

Thank you for the explanation. Another question. - you said 
The browser recognizes the feed types and is responsible for calling the 
getFeed and getEntry on the binding collection interface

How does this work? All the browser sees is 
"http://localhost:8083/atomAggregator", right ? How does the browser know 
that it should call getfeed()? Why doesn't the browser call "get"? I 
thought if you put a URL in -  the browser calls "get" on that resource.

 Sorry if this is off topic.

Hi Willis,

I am not the most knowledgeable in this area, so I welcome follow-on, 
more complete answers, but I believe the promote tag elevates the 
following component elements to an public declared service.

The browser recognizes the feed types and is responsible for calling the 
getFeed and getEntry on the binding collection interface, and this 
performing the calls on the public service methods (implemented in 
AggregatorImpl.java).
