Introducing the Sample

The sample shows a basic REST-based Web Services using JAX-RS (JSR-311). The REST server provides the following services:   

• A RESTful customer service is provided on URL http://localhost:9763/jaxrs_basic/services/customers/customerservice (say serviceURL). Users access this URI to operate on customer. 
• A HTTP GET request to URL ${serviceURL}/customers/123 returns a customer instance whose id is 123. The XML document returns the following:

<Customer>
   <id>123</id>
   <name>John</name>
</Customer>

• A HTTP GET request to URL ${serviceURL}/orders/223/products/323 returns product 323 that belongs to order 223. The XML document returns the following:

<Product>
   <description>product 323</description>
   <id>323</id>
</Product>

• A HTTP POST request to URL ${serviceURL}/customers with the following data adds a customer whose name is Jack.

<Customer>
   <name>Jack</name>
</Customer>

•  A HTTP PUT request to URL ${serviceURL}/customers with following data updates the customer instance whose id is 123.

<Customer>
   <id>123</id>
   <name>John</name>
</Customer>

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.
