Create WSDL Definition in memory

[Anil Ambati <aa...@us.ibm.com>]

Hi,
I have a need to create WSDL definitions dynamically. The interface of the
service is static. The binding and address extensibility element of Port
will change. I would like to know if any body have done this before and
would send me examples.

I started to do this to accomplish this.

public static ExtensibilityElement getEjbAddressExtElement()
  {
    EJBAddress ejbAddress = new EJBAddress();
    ejbAddress.setJndiName("ejb/org/apache/TestBean");
    ejbAddress.setJndiProviderURL("iiop://localhost:2809/");
    ejbAddress.setInitialContextFactory(
"com.ibm.websphere.naming.WsnInitialContextFactory");
    ejbAddress.setClassName("org.apache.TestBeanHome");
    return ejbAddress;
}
public static void main(String[] args)
{
    try
    {
      WSIFServiceImpl.addExtensionRegistry(
        new EJBExtensionRegistry());
      WSIFPluggableProviders.overrideDefaultProvider(
         "http://schemas.xmlsoap.org/wsdl/ejb/",
        new WSIFDynamicProvider_EJB());

      Definition def = WSDLFactoryImpl.newInstance().newDefinition();

      Port port = def.createPort();
      port.setName("SinkPort");
      port.addExtensibilityElement(getEjbAddressExtElement());

      Service fireflySubscriberService = def.createService();
      QName serviceName = new QName("http://xxx.yyy.com/wsdl/",
                                    "SinkService");
      fireflySubscriberService.setQName(serviceName);
      fireflySubscriberService.addPort(port);
      def.addService(fireflySubscriberService);

      WSDLWriter writer = WSDLFactoryImpl.newInstance().newWSDLWriter();
      StringWriter stringWriter = new StringWriter();
      writer.writeWSDL(def, stringWriter);
      System.out.println(stringWriter.toString());
    }
    catch (Exception ex)
    {
      ex.printStackTrace();
    }
}

But, I am getting the following exception:

[INFO] wsif - -WSIF0007I: Using WSIFProvider
'org.apache.wsif.providers.ejb.WSIFDynamicProvider_EJB' for namespaceURI
'http://schemas.xmlsoap.org/wsdl/ejb/'

      at com.ibm.wsdl.xml.WSDLWriterImpl.writeWSDL(Unknown Source)
      at wsdl.test.CreateWSDL.main(CreateWSDL.java:73)

Thanks in advance for your help.
