Getting Extra classes while creating Data Control in ADF

I am using Jdeveloper 11.1.1.6.0.

I was trying to create a Data Control from a Java class (containing event handling code) right click on the java class -> Create data Control.

 

I can see many data controls were created in my work space when the operation was completed

Example: java.io.InputStream.xml, java.net.URI.xml and many more.

 

Anybody please suggest is it a problem in Jdeveloper tool or I need to perform any additional step to remove all these files.

 

Regards,

Rajesh

    Please clarify, do you see classes generated or data controls?

     

    classes are normal, data controls are not. However without knowing your Java class it's hard to tell.

    Hello TimoHahn,

     

    I can see only the Data controls are getting generated (not the class files).

     

    Please find the code snippet for my class for which I generated data controls:

     

    public class ContexEvent {

        public ContexEvent() {

            super();

        }

       

        public void handleEvent(ActionEvent payload){

            UIComponent component = payload.getComponent();

            Map<String, Object> attrMap = component.getAttributes();

            FacesContext context = FacesContext.getCurrentInstance();

            ELContext elContext = context.getELContext();

            Application application = context.getApplication();

            ExpressionFactory factory = application.getExpressionFactory();

            ValueExpression valueExpr = factory.createValueExpression(elContext, "#{backingBeanScope.NameBean}", Object.class);

            NameBean nb=(NameBean)valueExpr.getValue(elContext);

            //String newVal = (String)payload.getNewValue();

            nb.setFirstName("Rajesh");

           

            AdfFacesContext adfContext= AdfFacesContext.getCurrentInstance();

            adfContext.addPartialTarget(nb.getNameLabel());

           

        }

    }

    It seems you are doing something wrong architecturally  - why are you trying to expose a Java class that deals with JSF components as a data control?

    This should be a managed bean. Data controls are for business services that are independent of UI layer.

    Hello

    DCBindingContainerValueChangeEvent type no extra Data Sources are created.

     

    Thank you very much.

    Again - it doesn't make sense to expose a bean that deal with contextual events as a data control - it is a view layer only bean and shouldn't be accessed through the binding layer!

     

    The additional datacntrols that are generated are in order to provide types for non-trivial attribute types.
