∟ServiceClient Class Loading WSDL 2.0 Documents

This section provides a test program to load WSDL 2.0 document with Axis2 1.4.1 ServicClient class. The loading failed, because the constructor is expecting WSDL 1.1 document by default.

According to the manual, Java Axis2 1.4.1 ServicClient class seems to support WSDL 2.0. See the comment on the portName parameter of the constructor method:

public ServiceClient(ConfigurationContext configContext,
                     java.net.URL wsdlURL,
                     QName wsdlServiceName,
                     java.lang.String portName)
              throws AxisFault

    Create a service client for WSDL service identified by the QName 
    of the wsdl:service element in a WSDL document.

    Parameters:
        configContext - The configuration context under which this 
           service lives (may be null, in which case a new local one 
           will be created)
        wsdlURL - The URL of the WSDL document to read
        wsdlServiceName - The QName of the WSDL service in the WSDL 
           document to create a client for
        portName - The name of the WSDL 1.1 port to create a client 
           for. May be null (if WSDL 2.0 is used or if only one port
           is there).

Here is test program, Axis2ServiceClientHelloWsdl20.java, that loads my WSDL 2.0 document, Hello_WSDL_20_SOAP.wsdl

/**

import java.io.PrintStream;

import javax.xml.namespace.QName;
import org.apache.axis2.client.ServiceClient;
import org.apache.axis2.context.ConfigurationContext;
class Axis2ServiceClientHelloWsdl20 {
   public static void main(String[] args) {
      PrintStream out = System.out;

// Setting initial values
      ConfigurationContext config = null;
      String wsdl = "file:///C:/herong/Hello_WSDL_20_SOAP.wsdl";
      String tns = "http://www.herongyang.com/Service/";
      String serviceName = "helloService";
      String portName = null;

      try {

// Creating a dynamic service client with a given WSDL
         ServiceClient client = new ServiceClient(
            config,
            new URL(wsdl), 
            new QName(tns, serviceName), 
            portName);

      } catch (Exception e) {
         e.printStackTrace(); 
      }
   }
}

But it failed to execute:

C:\herong>\local\jdk\bin\java -Djava.ext.dirs=\local\axis2\lib\
   Axis2ServiceClientHelloWsdl20

org.apache.axis2.AxisFault: WSDLException (at /wsdl:description):

   at com.ibm.wsdl.xml.WSDLReaderImpl.readWSDL(Unknown Source)

The ServiceClient constructor method is expecting a WSDL 1.1 document by default. I could not find a way to change this default behavior.
