-Feed Aggregator Sample
-======================================
-This sample demonstrates using the Feed binding to aggregate ATOM and RSS
-feeds and publish a new aggregated feed.
-
-The README in the samples directory (the directory above this) provides
-general instructions about building and running samples. Take a look there
-first.
-
-If you run the sample using ant, navigate to this sample directory and do:
-
-ant run
-
-OR if you don't have ant, on Windows do
-
-java -cp ..\..\lib\tuscany-sca-manifest.jar;target\sample-feed-aggregator.jar launch.LaunchFeedServer
-
-and on *nix do
-
-java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-feed-aggregator.jar launch.LaunchFeedServer
-
-You should see the following output on the screen.
-
-run:
- [java] Added Servlet mapping: http://localhost:8083/rssAggregator
- [java] Added Servlet mapping: http://localhost:8083/atomAggregator/*
- [java] Sample Feed server started (press enter to shutdown)
-
- [java] To read the aggregated feeds, point your Web browser to the following addresses:
- [java] http://localhost:8083/atomAggregator
- [java] http://localhost:8083/atomAggregator/atomsvc (for the Atom service document)
- [java] http://localhost:8083/rssAggregator
-
-As this point the aggregated Feeds are exposed by a web server started
-automatically by the SCA runtime. You can later stop the server by pressing enter.
-
-Now that the server is started you can point your Web browser to each URL of the
-aggregated feeds to see the information in your broswer. These URLs are:
-
-http://localhost:8083/atomAggregator
-http://localhost:8083/atomAggregator/atomsvc
-http://localhost:8083/rssAggregator
-
-** Please note that if your browser is not configured correctly to receive
-feed information, you will be prompted to open each file that contains the feed
-information in xml.
-
-Sample Overview
----------------
-The sample provides a single component exposing a Web resource.
-
-web-resource/
- src/
- main/
- java/
- feed/
- AggregatorImpl.java - implementation of the Feed
- aggregator component
- Sort.java - utilty interface
- SortImpl.java - implementation of the Sort component
- launch
- LaunchFeedServer.java - starts the SCA Runtime and
- publishes the aggregated feeds
- resources/
- FeedAggregator.composite - the SCA assembly for this sample
- feed-aggregator.png - a pictorial representation of the
- sample .composite file
- build.xml - the Ant build file
- pom.xml - the Maven build file
-
-
-Details of how this sample works
---------------------------------
-1. AggregatorImpl is used to implement the two main components here (RSSAggregator & AtomAggregator).
-2. AggregatorImpl directly implements the Tuscany Atom Collection interface. It is a component
- that provides an Atom feed to respond (see tuscany/modules/binding-atom-abdera)
-3. The AggregatorImpl component is not explicitly configured using nested <service> element nor its
- implementation class is annotated with @Service annotation. Instead, the Tuscany Atom Collection interface
- defines its services using @Remotable annotation.
-
-Building And Running The Sample Using Ant
------------------------------------------
-With the binary distribution the sample can be built and run using Ant using the
-following commands
-
-cd feed-aggregator
-ant compile
-ant run
-
-You should see the following output from the run target.
-
-run:
- [java] Added Servlet mapping: http://localhost:8083/rssAggregator
- [java] Added Servlet mapping: http://localhost:8083/atomAggregator/*
- [java] Sample Feed server started (press enter to shutdown)
-
- [java] To read the aggregated feeds, point your Web browser to the following addresses:
- [java] http://localhost:8083/atomAggregator
- [java] http://localhost:8083/atomAggregator/atomsvc (for the Atom service document)
- [java] http://localhost:8083/rssAggregator
-
-
-Building The Sample Using Maven
--------------------------------------------
-With either the binary or source distributions the sample can be built using
-Maven as follows.
-
-cd feed-aggregator
-mvn
-
