Apache JMeter - Testing RESTful WebServices

In this Tutorial let us see how to use Apache's JMeter to test the RESTful WebServices we developed in my previous post RESTful-web-service-with-spring-3x

1. Download JMeter Click here to download
2. This version requires Java 6 or later
3. Create a Thread Group and give a name, e.g "RestServiceTestingGroup"

5. Set "Ramp-up period (in seconds) to 1
6. Set "Loop Count" to 2

7. Right Click on RestServiceTestingGroup and choose Add->Sampler->HTTP Request

10. Give 8080 as "Port Number" value
11. Set "http" as Protocol
12. Choose "Post" as Method
13. Type "stock-service-war/stockService/getStockInformation" in the "Path" field
14. Open the "Body Data" Tab and paste the following XML
<?xml version="1.0" encoding="UTF-8" standalone="yes"?><stockRequest xmlns="http://com.mycompany.model.demo/stockRequest" xmlns:ns2="http://com.mycompany.model.demo/stockResponse"><stockSymbol>AAPL</stockSymbol><stockSymbol>GOOG</stockSymbol><stockSymbol>IBM</stockSymbol></stockRequest>
