JAX-RS Basics

Introducing the Sample

This sample demonstrates 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.

Building and Running the Sample    

Using Maven

1. Install and run the WSO2 Application Server. Refer to the  Installing Features for instructions.

2. From the base directory of this sample ( < CARBON_HOME >\samples\Jaxws-Jaxrs\jaxrs_basic) , the maven pom.xml file can be used to build and run the sample using either UNIX or Windows.

3. To build the sample and create a WAR file, run mvn clean install command.

4. Start the Application Server (run bin/wso2server.sh in Linux, or bin\wso2server.bat in Windows).

• mvn -Pdeploy (deploys the generated WAR file on WSO2 AS with related logs on the console)
• mvn -Pclient (runs the client)

Using Apache Ant  

1. Run "ant" on <AS_HOME>\samples\Jaxws-Jaxrs\jaxrs_basic directory to deploy the jaxrs_basic service on the server.

2. Start the application server and access its Management Console at https://localhost:9443/carbon.

3. Go to "Services -> List" menu to find the jaxrs_basic service listed on the "Deployed Services" window.

4. Execute "sh run-client.sh" or "run-client.bat" to run the client.

5. Try the sample with different QoS options which appear on its dashboard. Run "sh run-client.sh -help" for different options.
