∟WSDL 2.0 Element Model

This section describes the Element Model used by Woden to represent a WSDL 2.0 document. org.apache.woden.wsdl20.xml.DescriptionElement class represents the top element, Description.

Woden 1.0M8 also provides an element model to represent an WSDL document as XML element objects as shown in these steps:

1. Importing Woden element classes:

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;
...

2. Creating a WSDLReader with validation turned on

   WSDLFactory wFactory = WSDLFactory.newInstance();
   WSDLReader wReader = wFactory.newWSDLReader();
   wReader.setFeature(WSDLReader.FEATURE_VALIDATION, true);

3. Parsing a WSDL 2.0 document into a DescriptionElement object

   Description wDescription = wReader.readWSDL(wsdl);
   DescriptionElement eDescription = wDescription.toElement();

4. Retrieving sub elements out of the DescriptionElement object

   ServiceElement[] serviceList = eDescription.getServiceElements();
   BindingElement[] bindingList = eDescription.getBindingElements();
   InterfaceElement[] interfaceList 
      = eDescription.getInterfaceElements();
   TypesElement eTypes = eDescription.getTypesElement();
...
