WSDL to Java
• The second task we will look at is how to create a client interface.
• A client can be generated using the WSDL file created by the Axis toolkit.
• To create a client we will follow a three step process.
1. We will save the wsdl file to a local directory.
2. Use the WSDL Engine which is called WSDL2Java in the Axis toolkit to generate client side stubs.
3. Write a simple Java application that uses the stubs to invoke the web service.
• To save the WSDL file to the local machine simply use the browser’s “File -> Save As” menu option.
- The client will not have access to the MagicEightBall code, this WSDL file is the only thing shared
between client and server.
• The next step is to run a tool provided by Axis called WSDL2Java.
- All the detail on how to run this tool won’t be covered in the lecture. WSDL2Java is described in more
detail in the WSDL chapter and in the lab.
- The WSDL2Java tool is a Java program whose full name is org.apache.axis.wsdl.WSDL2Java.
- After running the WSDL2Java tool you should be able to find four classes created by the tool:
MagicEightBallServiceLocator, MagicEightBallService, MagicEightBallSoapBindingStub and MagicEightBall.
• The client you write can now use the classes created by WSDL2Java instead of creating an XML
payload by hand.
- The client program is below.
public class Application {
public static void main(String [] args) throws Exception
{
MagicEightBallService locator =
new MagicEightBallServiceLocator();
MagicEightBall service = locator.getMagicEightBall();
String ret = service.tellFortune("How you doing?");
System.out.println("Answer: " + ret);
}
}
- The output from this run might be something like the following.
