How to use wsdl in dynamic client

Question

In wls 700, I want to know how to write a dynamic client to invoke a webservice by
passing wsdl?
In the example directory, there is an example, but I would like to know how I can
customize to use my own wsdl? clientgen puts wsdl in client jar file why is that?

Hi fkeita,
If you haven't already done so, you should check out the following link in the BEA
product documentation:
http://edocs.bea.com/wls/docs70/webServices/client.html#1049007
Outside of that, you can always stayed tuned to the "dev2dev" page :-)

Hi Mike,
Can you elaborate more how I can find the url of wsdl?
Do you know any documentation which explains the process of using dynamic
clinet?
Thanks.

Hi fkeita,
The client.jar contains a "static" WSDL, because some folks like to avoid
making
a network (or internet) call to retrieve the "dynamic" one :-)
If you try to use "user-defined" types, with a WSDL and a "dynamic" client,
you will
experience "difficulties". This is due to the way the JAX-RPC defines the
createService()
method on the ServiceFactory class. Normally, this is the method you pass
the URL
to the WSDL you want to use. Currently, we call the WSDL parser in this
method, which
has a "side-effect" of needing to have the type mappings for your "user-defined"
types, already registered when it is called. With "stub-style" clients,
this is not
a problem (because the plumbing does this for you), but with "dynamic"ones
it doesn't.
Right now, the only real workaround is to have your client class extend
our weblogic.webservice.core.soap.SOAPElementImpl
class, as in the following code fragment:
#### START OF EXTRACT #####
import javax.xml.rpc.Call;
import javax.xml.rpc.namespace.QName;
import weblogic.webservice.core.rpc.ServiceImpl;
public class ServiceClient extends ServiceImpl
     public ServiceClient(String schemeHostPort) throws Exception
// We pass the URL for the "dynamic" WSDL in the
// first argument. The second argument is the
// path to the XML file that the <clientgen> Ant
// task recorded your typemapping info in. It is
// in your client.jar, along with the "static"
// WSDL I mentioned :-)
          super(
               (schemeHostPort == null ? "http://localhost:7001" : schemeHostPort)
+
"/mea/gateway?WSDL",
               "examples/webservices/jaxrpc/consumer/anamitra/dii/MEAGatewayService"
          //define qnames
          String targetNamespace = "http://www.bea.com/examples/MEAGateway";
          QName serviceName = new QName( targetNamespace, "MEAGatewayService" );
          QName portName = new QName( targetNamespace, "MEAGatewayServicePort");
          //create call
          Call call = super.createCall(
               portName,
               new QName(targetNamespace, "processExternalDataBatch")
          ArrayList alist = new ArrayList();
          alist.add(new String("One"));
          alist.add(new String("Two"));
          alist.add(new String("Three"));
          alist.add(new String("Four"));
          alist.add(new String("Five"));
          String result = (String)call.invoke( new Object[]{ alist } );
          System.out.println("result=" + result);
     public static void main( String[] args ) throws Exception
          System.setProperty("javax.xml.soap.MessageFactory", "weblogic.webservice.core.soap.MessageFactoryImpl");
          System.setProperty("javax.xml.rpc.ServiceFactory", "weblogic.webservice.core.rpc.ServiceFactoryImpl");
          new ServiceClient(args[0]);
//private:
     private final static boolean debug = false;
### END OF EXTRACT ###
Happy coding :-)
