Shopping Store Web Service Sample
=================================
This sample creates an shopping store application using Amazon's WS API interface. This sample intents to provide
the same services provided by Amazon but implementing them as SCA components. These services are provided through
a web service interface.
If you just want to run it to see what happens you need to run the server first. So, open a command prompt, navigate
to the shoppingstore sample directory and do:
1 - "ant" to compile it
2 - "ant run" to get the server up and running
3 - You should see the following output from the run target:
run:
[java] log4j:WARN No appenders could be found for logger (org.apache.axiom.om.util.StAXUtils).
[java] log4j:WARN Please initialize the log4j system properly.
[java] ToyApp server started (press enter to shutdown)
Once the server is running, it will be expecting requests from a client through its Web Service interface.
The WSDL describing the WS interface can be obtained opening a web broeser pointing to
http://localhost:8080/ShoppingStoreServiceComponent?wsdl
Sample Overview
---------------
Currently, the sample provides two components:
1 - ShoppingStoreService: that is wired to a reference with a web service binding and plays the role of a proxy service which offers all the operations exposed through the WSDL API and forwards every invocation to the actual service that in fact implements the service invoked.
2 - CartService: currently, this is the only component offering an actual service through the Shopping Store. It provides the following operations: CartCreate, CartAdd, CartClear, CartGet.

shoppingstore.wsdl - the service description that the
SCA reference uses to bind to. This
wsdl file is very similar to Amazon's
WSDL released on May 14th, 2007. Only
two modifications were done:
1 - Non-implemented services had to be
commented out from the WSDL
2 - Its location was modified in order
for it to point to this sample's address
shoppingstore.composite - the SCA assembly for this sample
test/ - no test provided so far
