WodenHelloComponent.java - Testing WSDL 2.0 Components

This section provided a tutorial example on how to create a WSDLReader to parse a WSDL 2.0 document into WSDL component objects.

To see how the Component model works, I wrote this testing program to parse my WSDL 2.0 document, Hello_WSDL_20_SOAP.wsdl, into components:

class WodenHelloComponent {
   public static void main(String[] args) {
      PrintStream out = System.out;
      String wsdl = "file:///C:/herong/Hello_WSDL_20_SOAP.wsdl";

      try {
      	
// Loading the WSDL 2.0 document
         WSDLFactory wFactory = WSDLFactory.newInstance();
         WSDLReader wReader = wFactory.newWSDLReader();
         wReader.setFeature(WSDLReader.FEATURE_VALIDATION, true);
         Description wDescription = wReader.readWSDL(wsdl);

// Implementation class information
         out.println("Reader object: "
            +wReader.getClass().getName());
         out.println("Description object: "
            +wDescription.getClass().getName());

// Getting WSDL 2.0 document components
         Service[] serviceList = wDescription.getServices();
         out.println("First service name: "
            +serviceList[0].getName());
  
         Binding[] bindingList = wDescription.getBindings();
         out.println("First binding name: "
            +bindingList[0].getName());
         out.println("First binding type: "
            +bindingList[0].getType().toString());

         Interface[] interfaceList = wDescription.getInterfaces();
         out.println("First interface name: "
            +interfaceList[0].getName());

         InterfaceOperation[] operationList 
            = interfaceList[0].getInterfaceOperations();
         out.println("First operation name: "
            +operationList[0].getName());
         out.println("First operation pattern: "
            +operationList[0].getMessageExchangePattern().toString());
         out.println("First operation style: "
            +operationList[0].getStyle()[0].toString());
            
         ElementDeclaration[] elementList 
            = wDescription.getElementDeclarations();
         out.println("# of element declarations: "
            +elementList.length);
         out.println("First element name: "
            +elementList[0].getName());

         TypeDefinition[] typeList 
            = wDescription.getTypeDefinitions();
         out.println("# of type definitions: "
            +typeList.length);
         out.println("First type name: "
            +typeList[0].getName());
 
      } catch (Exception e) {
         e.printStackTrace(); 
      }
   }
}

Result of this test program is listed below:

C:\herong>javac -cp .;\local\axis2\lib\* WodenHelloComponent.java

C:\herong>java -cp .;\local\axis2\lib\* WodenHelloComponent
WARNING: An illegal reflective access operation has occurred

No surprises, except the list of type definitions. My WSDL document does not define any types explicitly. But WSDL 2.0 automatically inherited 44 types defined in the XML Schema.
