Calling a WebService on a Web Dynpro Project

Question

Hi Experts,
I'd made an EJB, then a WebService of that.
I'd tested the url in a Browser, and everything works fine... I sent the values, and got the correct response.
Now i'm trying to call it in a Web Dynpro. I'd imported the model, added to the controller, generated a method and set all the values that the WS receive, however every time i execute an error occurs.
This is the error in Log Viewer:
com.sap.engine.services.webservices.addtions.exceptions.ProcessException: Cannot find the required parameter [RefPagamento] in the request message content.
This is the code i'm using:
wdContext.nodeRequest_PedidoAutorizacao().invalidate();
WS_PagamentoVisa model = new WS_PagamentoVisa();
wdContext.nodeRequest_PedidoAutorizacao().bind(new Request_PedidoAutorizacao(model));
IPublicHotelariaController.IPedidoAutorizacaoElement input = wdContext.createPedidoAutorizacaoElement(new PedidoAutorizacao(model));
wdContext.nodePedidoAutorizacao().bind(input);
input.setRefPagamento("12321321323");
wdContext.currentRequest_PedidoAutorizacaoElement().modelObject().execute();
I believe the input is not well formed in my code, but i can't understand where's the problem.
Can anyone help me, please?
Thanks in advanced,
Luis

Hi,
Assuming you context to be..
Context
--Request_PedidoAutorizacao (node)
PedidoAutorizacao (node)
RefPagamento (attribute)
<i>You are invalidating Request_PedidoAutorizacao which is your main node.This node contians subnode PedidoAutorizacao</i>
<i>which has the input attribute RefPagamento</i>.
// try the following
WS_PagamentoVisa model = new WS_PagamentoVisa();
Request_PedidoAutorizacao req = new Request_PedidoAutorizacao(model);
PedidoAutorizacao input = new PedidoAutorizacao(model);
req.setPedidoAutorizacao(input);
wdContext.nodeRequest_PedidoAutorizacao().bind(req);
wdContext.currentPedidoAutorizacaoElement.setRefPagamento("12321321323");
wdContext.currentRequest_PedidoAutorizacaoElement().modelObject().execute();
wdContext.nodeResponse.invalidate(); // invalidate your response node
