Apache Tuscany Alert Aggregator Demo
====================================
The alert aggregator demo provides an application, implemented using SCA, that
aggregates feeds together and exposes them using the following bindings:
binding.ws
binding.jsonrpc
binding.feed
The easiest way to get going is to build the demo
cd alert-aggregator-webapp
ant package
This will build a war file
demo-alert-aggregator-webapp.war
This war can be deployed to your web application container and tested (the war
has been tested with Tomcat 6.0.10).
The Web Application
-------------------
Once deployed point your browser at
http://localhost:8080/demo-alert-aggregator-webapp
Taking care to ensure the host name and port number match your local
configuration.
This launches a Javascript application in the browser that uses JSONRPC
to contact the server and retrieve a list of alert sources and alerts that
these sources are providing.
The default sources that you see are stored in the following file:
demo-alert-aggregator-webapp/WEB-INF/classes/sources.xml
This file has the following contents:
<ns0:Config xmlns:ns0="http://tuscany.apache.org/sca/demos/aggregator/types">
<ns0:Source Id="0" FeedType="rss">
<ns0:Name>BBC News</ns0:Name>
<ns0:Address>http://news.bbc.co.uk/</ns0:Address>
<ns0:LastChecked>10-Jun-2007 16:34:03</ns0:LastChecked>
<ns0:FeedAddress>http://newsrss.bbc.co.uk/rss/newsonline_uk_edition/world/rss.xml</ns0:FeedAddress>
</ns0:Source>
<ns0:Source Id="1" FeedType="rss">
<ns0:Name>Engadget</ns0:Name>
<ns0:Address>http://www.engadget.com</ns0:Address>
<ns0:LastChecked>10-Jun-2007 16:34:03</ns0:LastChecked>
<ns0:FeedAddress>http://www.engadget.com/rss.xml</ns0:FeedAddress>
</ns0:Source>
</ns0:Config>
You may want to adjust the "LastChecked" values to change the number of
alerts that are displayed in the first instance.
Using A Feed Reader
-------------------
As this SCA application also uses the binding.feed binding you can use your
favourite feed reader to read the aggregated alerts. To do this point your
feed reader at
http://localhost:8080/demo-alert-aggregator-webapp/services/AlertsFeedServiceRSS
Again taking care to ensure that the host name and port number match you
local configuration.
Using Web Services
------------------
The SCA application also uses binding.ws to provide a SOAP/HTTP interface.
The demo client that uses this interface is not yet available.
Building The Sample Using Ant
-----------------------------
With the binary distribution the sample can be built using Ant as follows:
cd alert-aggregator-webapp
ant package
Building The Sample Using Maven
-------------------------------
With the source and binary distributions the sample can be built using Maven
as follows:
cd alert-aggregator-webapp
mvn
The Maven build runs an integration test after building the war file.
