∟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:

import java.io.PrintStream;
import org.apache.woden.WSDLFactory;
import org.apache.woden.WSDLReader;

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:

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

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

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.
