JAX-WS Client

[Mize-ze]

Hello,
I have a webservice up and running on a JBoss 4.2 AS .

I am trying to build a simple client to invoke a method on the
webservice,

//get the generated service implementation (My implementing class is
called InComing)
// iInComingService is a generated class (used wsimport)

service = new InComingService();

// retrieving the port of the webservice - causes "InComing is not an
interface!!"
inComing port = (InComing)service.getInComingPort();

//Calling the method
System.out.print(port.loadTransactions(""));



When trying to get the port I recieve the following exception:

Exception in thread "main" java.lang.IllegalArgumentException:
com.retalix.insync.storepi.test.InComing is not an interface

any clues? as far as I understood I don't have to retrieve an interface
