- WSDL 2.0 Validator

This section provided a tutorial example on how to create a WSDL 2.0 document validator with the Woden Java API.

If we use the WSDLReader.readWSDL() parse method from the Woden API, we can actually create a very simple WSDL 2.0 document validator,

import org.apache.woden.WSDLFactory;
import org.apache.woden.WSDLReader;
import org.apache.woden.wsdl20.Description;
class Wsdl20Validator {
   public static void main(String[] args) {
      if (args.length < 1) {
         System.err.println("Usage: java Wsdl20Validator URL");
         System.err.println("URL example: file:Hello_WSDL_20_SOAP.wsdl");
      try {
         WSDLFactory wFactory = WSDLFactory.newInstance();
         WSDLReader wReader = wFactory.newWSDLReader();
         wReader.setFeature(WSDLReader.FEATURE_VALIDATION, true);
         Description wDescription = wReader.readWSDL(args[0]);
         System.out.println("This is a valid WSDL 2.0 document.");
      } catch (Exception e) {

First, let's try it with a valid WSDL 2.0 document, Hello_WSDL_20_SOAP:

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

C:\herong>java -cp .;\local\axis2\lib\* Wsdl20Validator \

This is a valid WSDL 2.0 document.

Now, let's try it with an invalid WSDL 2.0 document:

C:\herong>java -cp .;\local\axis2\lib\* Wsdl20Validator \

2:55:23 PM org.apache.woden.internal.ErrorHandlerImpl error
SEVERE: Woden[Error],5:56,null,cvc-elt.1.a: Cannot find the declaration of
   element 'wsdl:definitions'.

2:55:23 PM org.apache.woden.internal.ErrorHandlerImpl fatalError
SEVERE: Woden[Fatal Error],0:0,WSDL514,It appears as though you are trying
   to parse a WSDL 1.1 document but Woden is a WSDL 2.0 parser.

WSDLException: faultCode=INVALID_WSDL: Fatal WSDL error:
0:0,WSDL514,It appears as though you are trying to parse a WSDL 1.1 document
  but Woden is a WSDL 2.0 parser.:
	at org.apache.woden.internal.ErrorReporterImpl.reportError(...)
  at org.apache.woden.internal.BaseWSDLReader.parseDescription(...)
	at org.apache.woden.internal.DOMWSDLReader.readWSDL(...)
	at Wsdl20Validator.main(

Not too bad. It does detect the obvious error.
