I don't see any file called AlertsService . I am in theTuscany\apache-tuscany-sca-1.2.1-incubating\tuscany-sca-1.2.1-incubating\samples\feed-aggregator\src\main\java dir. There are only 4 files here and the .composite file seems to be the only other file involved, unless I am missing something.
Where is this AlertsService file ? I understand the promotion. But I thought to be promoted a service must be declared some place - seems like in this case the service is promoted with out being declared any place. Also my original questions 2 and 3 are still unclear to me. Sorry, but I still don't see how AggregatorImpl.getFeed and AggregatorImpl.Feed are called when a browser hits "http://localhost:8083/rssAggregator"; or "http://localhost:8083/atomAggregator"; Willis C White III IQ Technology Projects IBM CIO Technology & Innovation Poughkeepsie, NY 12601 Home office 845 331-5134 Cell 845 853-3827 "Raymond Feng" <[EMAIL PROTECTED]> 07/22/2008 01:26 PM Please respond to [email protected] To "tuscany-user" <[email protected]> cc Subject Re: Questions about feed-aggregator sample Resending as the previous message triggered the spam alert and was rejected From: Raymond Feng Sent: Tuesday, July 22, 2008 10:12 AM To: [email protected] Subject: Re: Questions about feed-aggregator sample Hi, 1) This is a service promotion that makes the AtomAggregator component service public and further configure the binding to be ATOM (i.e., expose it as an ATOM service). You can also inline the binidng.atom configuration under the <component> element. There are differences between the two configurations. For the promotion, the composite can be used to implement another SCA component (implementation.composite for recursive composition)and the promoted service becomes a service at the higher level component. For the inline case, you just configure the binding. 2) All operations on the AlertsService interface can be called. 3) The @Remotable applies to the interface instead of the component impl class. Please note AlertsService interface has the @Remotable.
