Authentication Error ? Adaptive webservice model

[Former Member]

While trying to use an adaptive webservice model, I'm getting a commun error:

Exception on execution of web service with WSDL URL 'http://srcs00048:50200/UserValidator/Config1?wsdl ' with operation 'validateUser' in interface 'UserValidatorVi_Document'

I have already tested the webservice and It's working fine in webservice navigator when using the correct username and password.

So, I found some workarounds to set the username and password in my controller before I call the execute method:

import javax.xml.rpc.Stub;
import com.sap.tc.webdynpro.model.webservice.api.IWDWSInvocationModifier;
import com.sap.engine.services.webservices.espbase.client.dynamic.DInterfaceInvoker;
...
wdContext.currentXXXXElement().modelObject().wdSetInvocationModifier(
  new IWDWSInvocationModifier() {
    public void doModifyInvocation(final Object port) {
      if ( port instanceof Stub ) {
        final Stub stub = (Stub)port;
        stub._setProperty(Stub.USERNAME_PROPERTY,  "username");
        stub._setProperty(Stub.PASSWORD_PROPERTY, "password");
      } else if (port instanceof DInterfaceInvoker) {
        final DInterfaceInvoker invoker = (DInterfaceInvoker)port;
        invoker.setProperty(Stub.USERNAME_PROPERTY,  "username");
        invoker.setProperty(Stub.PASSWORD_PROPERTY, "password");
      } else
         throw new RuntimeException("This 'clever' hack does not work"); 
    }
    public void doModifyAfterInvocation() {}
  }
);
 

And.... http://wiki.sdn.sap.com/wiki/display/WDJava/ExceptiononExecutionofWeb+Service

Both did not work.....

What am I doing wrong?

Hi Vinicius

Check logs and traces for more helpful error message with additional hints. The problem might be not in user authentication, but generic web-service availability by the URL.

Now I could see that my problem is not about authentication. I built a new webservice without any need of authentication for testing...

So I tested it at webservices navigator and it is working fine, and also it is not asking any user or password.

Then, I created another controller in my webdynpro and using the template tool, I mapped the model with my context. So now I have a method like this in my controller:

public void executeRequest_ValidateGntUser( )
  {
    IWDMessageManager manager = wdComponentAPI.getMessageManager();
    try
    {
      wdContext.currentRequest_ValidateGntUserElement().modelObject().execute();
      wdContext.nodeResponse().invalidate();
      wdContext.nodeValidateGntUserResponse().invalidate();
    }
    catch(Exception e)
    {
	     StringWriter sw = new StringWriter();
		 e.printStackTrace(new PrintWriter(sw));						 
						 
         manager.reportException(e.getMessage() + "  " + sw.toString(), false);
      	  
    }

After this, I created a view called loggin and mapped with the context. So now I have avaiable the Request_ValidateUser_Gnt Node. I used the template tool and created a form.

Then, I have manually created the nodes like this:

public void wdDoInit()
  {
    Gnt_user_auth model = new Gnt_user_auth();
    wdContext.nodeRequest_ValidateGntUser().bind(new Request_ValidateGntUser(model));
    wdContext.nodeRequest_ValidateGntUser().nodeValidateGntUser().bind(new ValidateGntUser(model));
    wdContext.nodeRequest_ValidateGntUser().nodeResponse().bind(new Response_ValidateGntUser(model));

  }

Then, I created a view for the result. I used the same logic that I used at loggin view (Using template) but for the Reponse node.

After this, I created a firePLug and a button at Loggin view. So, before firing this plug, I called this method:

wdThis.wdGetGnt_user_authCustController().executeRequest_ValidateGntUser()

Anyway, I could see that this problem is not about authentication because it is still the same problem. The only thing I was able to see is that in my stacktrace there is a line that says: Caused by: java.lang.reflect.InvocationTargetException: Cannot find the required parameter [username] in request message content. at

This username parameter is needed at my webservice implementation. Problably it was not found in my request.

Does anyone have any idea?

Hi

Try to remove the code below and execute the service without it. I think the code causes the problem with parameter "username".

if ( port instanceof Stub ) {
        final Stub stub = (Stub)port;
        stub._setProperty(Stub.USERNAME_PROPERTY,  "username");
        stub._setProperty(Stub.PASSWORD_PROPERTY, "password");
      } else if (port instanceof DInterfaceInvoker) {
        final DInterfaceInvoker invoker = (DInterfaceInvoker)port;
        invoker.setProperty(Stub.USERNAME_PROPERTY,  "username");
        invoker.setProperty(Stub.PASSWORD_PROPERTY, "password");
      }

BR, Siarhei

Siarhei ,

After creating the new test webservice, I removed this code. I'm not using it anymore since there is no need to authenticate.
