Now, let's test the Greeting Web Service function you have just created.
Click on the Run button on the Studio's toolbar.
The
application should automatically load in your default browser and
display the page below, with a link to the Greeting Web Service. Click
the Greeting Web Service link.
Your browser will now show the GreetingService.wso page:
There are a number of things to note on this page:
The page that is used to access this Web Service (http://localhost/GreetingWebService/GreetingWervice.wso) is determined by the psServiceName property of the WSO that you set in the Studio's properties window.
The title "Greeting Web Service" is the value of the WSO's psServiceTitle property.
The description of the service, right beneath the title is the value of the WSO's psDocumentation property.
The list of operations is created by an enumeration of all published functions in your WSO. In the case of our Greeting WSO, Greeting is the only published function.
The description below the Greeting function is the description you typed into the "Method Properties" dialog in the Studio.
Click on the Service
Description link to see the WSDL document for this service.
This WSDL (http://localhost/greetingwebservice/greetingservice.wso?WSDL)
is what is use by client programs to consume (access) this web service.
You will use this URL in the next tutorial section on the Creating
a Web Service Client Class page.
When you are done viewing the WSDL, click on the Back
button of your browser to return to the WSO page for your Web Service.
Click the Greeting
link to load the test page for the Greeting function. You should see
the following page:
On this page, you can actually test your web service's functionality.
The Studio has created the page for you to test calling the Greeting
web service function.
The test page that DataFlex Studio creates for your Web Service is just that, a test page. Normally, a Web Service function is called from a Web Service client without any visual interface. The test page provides a quick and simple way of testing your Web Service's functionality without having to create a client for it.
Type your name into the
sName window and click the
Invoke button. Another web
page should open, displaying the result of the Greeting function:
The Web Service you have just created could now be placed on a Web server and access by Web Service client's designed in any tool that supports web services anywhere in the world.
