Re: invoke methods wsdl file

[Tom Ziemer]

Hi,
---
call.setOperationName("someMethod");
String ret = (String) call.invoke( new Object[] { new Integer(6) } );
---
First you set the operation name, that is, the service's method you want 
to call then you excute the method (call.invoke()). The parameters for 
the service are passed as an array, so basically that's a rather 
complicated way of calling:

service.someMethod(new Integer(6));
The service in turn returns a String, which you have to cast, since 
invoke() only returns an java.lang.Object.

I'm not sure what you mean by "carry on". At this point the client has 
called the service and a result was returned so basically the 
transaction is finished. What else do you want to do?

Reagrds,
Tom

Hi there!
You could let ANT (using the axis-tasks) generate the necessary stub 
files. In my opinion that is a much cleaner approach. Then you simply 
call the service as if it were a local object:

// the locator is generated by axis/ant...
someLocator locator = new someLocator();
// ...the service object as well
someService service = null;
try
{
  // get a reference
  someService = somelocator.getSomeService();
  // call the service
  String msg = someService.someMethod();
  ...
}
...
If you want to do it the other way:
String endpoint = "http://xxx/someService";;
Service service = new Service();
Call call = (Call) service.createCall();
call.setTargetEndpointAddress(new java.net.URL(endpoint));
// define operation (method)
call.setOperationName("methodToCall");
// call the service
String txt = (String) call.invoke(new Object[] { new Integer(6) });
...
As I said - I prefer the former way. Hope this helps you to get started.
Regards,
Tom

Hello
I've got to develop a web service client, but don't know where to start
I have the external wsdl file which exposes the methods i wish to 
invoke.

Is it something like this
public static void main(String args[])
{
URL url = new 
URL("http://thirdpartycallservice/third_party_calling_service.wsdl";);
Service service = new Service();
Call call = (Call)service.createCall();
.
.

}

I don't know the next code to continue
Any help much appreciated
