JAX-RS Advanced

• Sample location - <AS_HOME>/samples/Jaxws-Jaxrs/jaxrs_starbucks_service
• Sample webapp name - jaxrs_starbucks_service.war

This sample shows some advanced functionalities of REST-based Web Services using JAX-RS (JSR-311). Please note that this sample was called jaxrs_sample_02 in the AS 5.1.0 release. It has been renamed to provide better clarity. This JAX-RS webapp provides following services:    

• A RESTful Starbucks outlet service is provided on URL http://localhost:9763/jaxrs_starbucks_service/services/Starbucks_Outlet_Service (say serviceURL). Users access this URI to perform operations of drink orders.      

• A HTTP GET request to URL ${serviceURL}/orders/123 returns a drink order added with the generated id 123. The JSON document returns: 

  {
     "Order":{
         "orderId":"123",
         "drinkName":"Vanilla Flavored Coffee",
         "additions":"Milk",
         "locked":false
     }
  }
  

• A HTTP POST request to URL ${serviceURL}/orders  with the following data adds an order. 

  <Order>
     <drinkName>Mocha Flavored Coffee</drinkName>
     <additions>Caramel</additions>
  </Order>

• An id for this order is generated at server-side and returned in the response.   The response body looks like the following in JSON format. 

  {"Order":{
     "additions":"Caramel",
     "drinkName":"Mocha Flavored Coffee",
     "locked":false,
     "orderId":"ee1a9ec2-c8a5-4afe-8585-74df591f9990"
  }}

• A HTTP PUT request to URL ${serviceURL}/orders with the following data, where the 'orderId' is set to the one received in the response body when the order was added: 

  {
     "Order":{
         "orderId":"ee1a9ec2-c8a5-4afe-8585-74df591f9990",
         "additions":"Chocolate Chip Cookies"
     }
  }

• It updates the 'additions' of the order "ee1a9ec2-c8a5-4afe-8585-74df591f9990" from "Caramel" to "Chocolate Chip Cookies". The response will be in XML-format as follows.

  <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
     <Order>
        <additions>Chocolate Chip Cookies</additions>
        <drinkName>Full Leaf Green Tea</drinkName>
        <locked>true</locked>
        <orderId>ee1a9ec2-c8a5-4afe-8585-74df591f9990</orderId>
     </Order>

• A HTTP DELETE request to URL ${serviceURL}/orders/ee1a9ec2-c8a5-4afe-8585-74df591f9990 with an empty request body will delete the order details of order "ee1a9ec2-c8a5-4afe-8585-74df591f9990".

The client code demonstrates how to send HTTP GET/POST/PUT/DELETE requests whereas the server code demonstrates how to build a RESTful endpoint through JAX-RS (JSR-311) APIs.
