What is Web Service Testing? It will the current conversion rates between the different countries currency.
This service we can use in our applications to convert the values from one currency to the other currency. Now lets look at above steps Step 1 to 4: SoapUI is one of the popular tool which will help us to test the web services.
In fact you can use the any programing language which is capable of sending the XML request to the web service provider application over the http and able to parse and validate the response XML against the expected result. Generally web service takes the request and sends the response in the XML format. Apache Axis2 API project is a Java implementation API, which will be used to create the Web services for both server side service provider and client side service consumer. We can write a small Java program using the API to create the web service.
Axis2 will generate the WSDL from Java program which will be used to communicate the services offered by the web service. We can use the same Axis2 to generate the Java class stub from WSDL file which we can use as a client program to generate the web service request, to send the request to the service end point and to process the response. Basically we will create a simple Java program in which we will instantiate the stub class. Using the stub we will invoke the request method by passing all the required information.
Stub program will convert that request into XML request format and sends it the service end point which will read the request and processes the request and sends the response in XML format. The XML response will be converted into Java class by stub and returned to the actual program.
Step e Next we have to create the client program, through which we will send the actual request using the generated stubs. Open the eclipse and create the new Java project and select the folder which we have created above. Step f Add all the axis2 related jars to project build path, which will be there in lib folder of the axis2 software folder for ex: Java and instantiate stub object. Using the stub object we can call all the supported methods of the particular WebService.
