∟WSDL 2.0 Element Model Test

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

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

import java.io.PrintStream;
import org.apache.woden.WSDLFactory;
import org.apache.woden.WSDLReader;
import org.apache.woden.wsdl20.Description;
import org.apache.woden.wsdl20.xml.DescriptionElement;
import org.apache.woden.wsdl20.xml.ServiceElement;
import org.apache.woden.wsdl20.xml.BindingElement;
import org.apache.woden.wsdl20.xml.InterfaceElement;
import org.apache.woden.wsdl20.xml.InterfaceOperationElement;
import org.apache.woden.wsdl20.xml.TypesElement;
class WodenHelloElement {
   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);

// Converting the document from Component model to Element model
         DescriptionElement eDescription = wDescription.toElement();

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

// Getting WSDL 2.0 document elements
         ServiceElement[] serviceList 
            = eDescription.getServiceElements();
         out.println("First service name: "
            +serviceList[0].getName());

         BindingElement[] bindingList 
            = eDescription.getBindingElements();
         out.println("First binding name: "
            +bindingList[0].getName());
         out.println("First binding type: "
            +bindingList[0].getType().toString());

         InterfaceElement[] interfaceList 
            = eDescription.getInterfaceElements();
         out.println("First interface name: "
            +interfaceList[0].getName());

         InterfaceOperationElement[] operationList 
            = interfaceList[0].getInterfaceOperationElements();
         out.println("First operation name: "
            +operationList[0].getName());
         out.println("First operation pattern: "
            +operationList[0].getPattern().toString());
         out.println("First operation style: "
            +operationList[0].getStyle()[0].toString());
            
         TypesElement eTypes = eDescription.getTypesElement();
         out.println("Types system: "+eTypes.getTypeSystem());
 
      } catch (Exception e) {
         e.printStackTrace(); 
      }
   }
}

Result of this test program is listed below:

C:\herong>\local\jdk\bin\java -Djava.ext.dirs=\local\axis2\lib\
   WodenHelloElement

Description object: org.apache.woden.internal.wsdl20.DescriptionImpl
First service name: {http://www.herongyang.com/Service/}helloService
First binding name: {http://www.herongyang.com/Service/}helloBinding
First binding type: http://www.w3.org/ns/wsdl/soap
First interface: {http://www.herongyang.com/Service/}helloInterface
First operation name: {http://www.herongyang.com/Service/}Hello
First operation pattern: http://www.w3.org/ns/wsdl/in-out
First operation style: http://www.w3.org/ns/wsdl/style/iri
Types system: http://www.w3.org/2001/XMLSchema

Cool. The element model is also easy to use.
