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 you 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 you local
|
|
configuration.
|
|
|
|
This launches a Javascript application in the browser that uses JSONRPC
|
|
to contact the server and retrived a list of alert sources and alerts that
|
|
these sources are providing.
|
|
|
|
There default sources that you see are stored in a file in the following
|
|
file
|
|
|
|
demo-alert-aggregator-webapp/WEB-INF/classes/sources.xml
|
|
|
|
This files 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.
