BeanSerializer

[Ben Souther <bs...@fwdco.com>]

Can anyone point me to an example of a Java client that calls a webservice who's return type is a JavaBean?
I've looked at  samples/userguide/example5/BeanService.java. in the samples section of Axis. This example demonstrates how to send a bean as an argument but doesn't show how to recieve one as a returnType.


Here is my attempt:
 try{
            String  endpoint = "http://localhost:8080/axis/services/EmployerService";
            Service service  = new Service();
            System.out.println("service Created");
            
            Call  call = (Call)service.createCall();
            System.out.println("Call Created");
            
            call.setTargetEndpointAddress(new java.net.URL(endpoint));
            QName qn = new QName("EmployerService", "getEmployerData");
            call.setOperationName(qn);
            
            System.out.println("ready to invoke call....");
            
            EmployerBean employerBean = (EmployerBean)call.invoke(new Object[]{"1"});
            System.out.println("Call invoked...");
            
            if(employerBean == null)
                System.out.println("EmployerBean is null");
            
            String employerName = employerBean.getEmployerName();
            System.out.println("Name: " + employerName);
        }catch(Exception e){
            System.out.println("Error: " + e.toString());
        }
    }


Here is the error that I am fighting with:

Thank you.
