The online store tutorial application is now pretty much working.
It shows how SCA allows a business to create an online store composite
application and recompose and evolve it as the business changes and expands.
1. How to build an online store to sell fruits online with an SCA
composite, a few java components (a shopping cart, a catalog, a currency
converter), and a Web 2.0 AJAX UI.
2. How to recompose/rewire the store application after a merger with a
vegetables company and offer a merged catalog of fruits and vegetables.
3. How to evolve the store's infrastructure by integrating the shopping
cart service component with a database.
4. How to configure the store composite to start offering Web services
to other online stores.
5. How to expand to another geography, with a slightly different UI,
currency, and wiring to different online services.
Slides showing these steps are available there:
http://svn.apache.org/repos/asf/incubator/tuscany/java/sca/tutorial/Tutorial.pdf
The code is there:
http://svn.apache.org/repos/asf/incubator/tuscany/java/sca/tutorial/
(the amazon and www-cloud modules are work in progress, not yet
integrated with what I just described)
If anybody is interested in contributing documentation, I think we could
use some help to document the above steps and how to develop the online
store using Tuscany in more details.
On a different note, the tutorial does not yet show how to distribute
the application across different containers like Tomcat or Geronimo. I
think we should add that aspect too, I'll post some ideas on that in a
different email.
