Empty Axis2 array

I am getting null insted of an empty array on the client side when my POJO axis2 method returns an empty array. I understand that the problem is in the WSDL.

Is there a way to set up axis 2 to generate a valid WSDL? I am creating an axis service programmatically:

ConfigurationContext context = ConfigurationContextFactory.createConfigurationContextFromFileSystem(null, null);

Map<String, MessageReceiver> mrMap = new HashMap<String, MessageReceiver>();
mrMap.put("http://www.w3.org/ns/wsdl/in-only", RPCInOnlyMessageReceiver.class.newInstance());
mrMap.put("http://www.w3.org/ns/wsdl/in-out",  RPCMessageReceiver.class.newInstance());

AxisService service = AxisService.createService(...);
context.getAxisConfiguration().addService(service);
SimpleHTTPServer server = new SimpleHTTPServer(context, port);

server.start();

      

        
        
        
      

    

And can anyone give an example of a custom SchemaGenerator for Axis2 services?

Thanks.
