Consume Web Service in Web Dynpro

Question

Hi Experts,
I´m currently trying to learn web dynpro development.
Scenario: I have one component which embed two views. One view is for enter customer number and in the other view I will see the name of the customer. The name of this customer is provided in a sap erp2005. I have develop a function modul and wich gave me the appropriate data(customer name). Then I create a web service base on this function module.
When I test this web serviec in WSNavigator, I get the customer name, so the web service is working well.
My Problem is: I can´t invoke this Web Service in Web Dynpro. My steps to invoke web service were: create a model with the web service wsdl and then I add this model in the component (in "Used Models").
I have create a application and assign it to the component. When I "Deploy new archive and Run" the application I be come the error: "Configuration not found for application: demo.sap.com/test_wd3,serviceRefId:7fecf23b-0895-48f3-9902-0e7015a705c3. Please check the configuration details from the NWA. You may have not assigned the Service Group to a Provider System, or the generation of the configuration has failed."
What do I have to consider or to set up?
It is right to assign the input field to the context parameter?
PS: I have followed the steps in this tutorial, but I don´t use XI or PI

Answer 1

Hi,
I have the following message error:
Exception on execution of web service with WSDL URL
'http://j2eeserver:port/xxxx/Config1?wsdl'
with operation 'RequestNode' in interface
'urn:xxxxx'
When i debugged it, I found the following error:
Cannot find the required parameter [unTipoProducto] in request message content.
What is wrong?, I pasted the code of my method, that call to web service in the component controller.
  public void Alta_Entrega( )
    //@@begin Alta_Entrega()
     String tipoProducto = wdContext.currentAlta_EntregaElement().getUnTipoProducto();
     Request_Alta_Entrega entregaMO = wdContext.currentRequest_Alta_EntregaElement().modelObject();
     if (!wdContext.currentAlta_EntregaElement().getUnTipoProducto().equalsIgnoreCase("")){
          IWDMessageManager manager = wdComponentAPI.getMessageManager();
          if (logger.beDebug()) {
            entregaMO.wdSetInvocationLogEnabled(true); //switch on logging for this model object
          try{
               entregaMO.setInvokerProperty(Stub.USERNAME_PROPERTY,"xxx");
               entregaMO.setInvokerProperty(Stub.PASSWORD_PROPERTY,"xxx");
               entregaMO.execute();
               wdContext.nodeResponse().invalidate();
               wdContext.nodeAlta_Entrega().invalidate();
          }catch (Exception e){
               manager.reportException(e.getMessage(),false);
          logger.debugT(entregaMO.wdGetRequestLog()); //request log (HTTP header + SOAP request)
          logger.debugT(entregaMO.wdGetResponseLog()); //response log (HTTP header + SOAP response)
          logger.debugT(entregaMO.associatedModelClassInfo().getModelInfo().toString()); //model metadata in XML format
          logger.debugT(entregaMO.toString()); //model object tree in XML format (= model context node content)
I hope you can understand me, because my english is very bad!!.
Thank you.
