Calling a WebService on a Web Dynpro Project

[luscruz]

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

So tomorrow i'll reply with more details, and set the rewarding points.

Once again thanks,

Hi Luis,

You are invalidating the node first.First execute the the model then invalidate.

WS_PagamentoVisa model = new WS_PagamentoVisa();

wdContext.nodeRequest_PedidoAutorizacao().bind(new Request_PedidoAutorizacao(model));

IPublicHotelariaController.IPedidoAutorizacaoElement input = wdContext.createPedidoAutorizacaoElement(new PedidoAutorizacao(model));

input.setRefPagamento("12321321323");

wdContext.nodePedidoAutorizacao().bind(input);

wdContext.currentRequest_PedidoAutorizacaoElement().modelObject().execute();

wdContext.nodeRequest_PedidoAutorizacao().invalidate();

Would you please post the exact structure of you model node that contains "RefPagamento" parameter .

Regards,

Mithu

Hi,

Can you do the setting of refPagemento first and then the binding of input variable.

i.e

IPublicHotelariaController.IPedidoAutorizacaoElement input = wdContext.createPedidoAutorizacaoElement(new PedidoAutorizacao(model));

input.setRefPagamento("12321321323");

wdContext.nodePedidoAutorizacao().bind(input);

wdContext.currentRequest_PedidoAutorizacaoElement().modelObject().execute();
