| This directory contains a multi-channel Music Store application. |
| |
| This application can be used as a Voice -or- Graphical User Interface |
| for a music store application, allowing users to browse through the music |
| albums available on Amazon, assemble a shopping cart and then retrieve |
| the shopping cart on the Amazon web site. |
| This application uses the Amazon Web Services, and hence, a real backend. |
| |
| The two channels are: |
| 1) The Voice channel which uses RDC based JSPs [ in ./voice ] |
| The starting point for the voice channel is: |
| ./voice/mainmenu.do |
| |
| 2) The GUI channel for small devices [ in ./gui ] |
| The starting point for the GUI channel is: |
| ./gui/mainmenu.do |
| |
| ##### |
| YOU NEED A AMAZON WEB SERVICES SUBSCRIPTION ID |
| TO TRY OUT THIS SAMPLE APPLICATION. |
| |
| This was the URI for AWS when this application was authored: |
| http://www.amazon.com/gp/aws/landing.html |
| Click on "Register for AWS" on the top left. |
| |
| ONCE YOU GET THE ID, UPDATE THE ../WEB-INF/web.xml |
| FILE SUCH THAT THE <context-param> with name |
| com.amazon.ecs.SubscriptionId |
| CONTAINS YOUR ID AS THE <param-value> |
| ##### |
| |
| |
| This is the overall control flow: |
| 1) Browse - Asks user to select the category and/or genre of the |
| music the user is interested in. Categories include types such as |
| Top Sellers, New Releases etc. Genres include Rock, Country, Dance |
| etc. |
| 2) Select / list similar - Once a list of top 10 results matching |
| the query in (1) are presented to the user, the user can select |
| one of these and carry out further interaction such as getting |
| the album description and looking for similar music albums. |
| 3) Add to cart - The user can add music albums of interest to the user's |
| shopping cart. This is a shopping cart created at Amazon using the |
| web services API. Steps (1) through (3) can be repeated as many times |
| as needed. |
| 4) Check out - On the voice side, the user is provided with cart ID. |
| The user then uses a web/HTML browser to visit ../getcart.jsp, |
| and uses the above cart ID in the displayed form to be redirected to |
| the Amazon web site where the user can complete the transaction and buy |
| the items added via the VUI to the user's shopping cart. On the GUI |
| side, the user is simply redirected to the Amazon web site to complete |
| the transaction. |
