∟Wsdl20Validator.java - 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, Wsdl20Validator.java:

/* Wsdl20Validator.java
 * Copyright (c) 2009 HerongYang.com. All Rights Reserved.
 */
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");
         return;
      }
      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) {
         e.printStackTrace();
      }
   }
}

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

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

herong> java -cp .;\local\axis2\lib\* Wsdl20Validator \
   file:Hello_WSDL_20_SOAP.wsdl

This is a valid WSDL 2.0 document.

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

herong> java -cp .;\local\axis2\lib\* Wsdl20Validator \
   file:Hello_WSDL_11_SOAP.wsdl
