ADF Basics: Using CSS to change appearance of application (Skins and Styles in ADF Faces)

Hello All
This is a basic post about using CSS in ADF applications, how can you change appearance of ADF application using Skins (.css file)
See the steps to create and apply css in your ADF applications

• Create a Fusion Web Application and create a page
• Add Some ADF Faces component (input text,button,panel box, panel collection etc)
• Now to change appearance of default ADF Faces components , create an ADF Skin
•  Right click on ViewController--->New--->Web Tier--->JSF/Facelets--->ADF Skin 





• By default ADF Skin name is like skin1,2 etc




• After creating ADF Faces skin open it and, on left you will see all components as Button, Layouts, Output text and so on. this is ADF Skin Editor





• Now expand the components that you want to change , change it's color(on active, focus , hover etc) and other properties. See in image below





• After creating your ADF Skin ,open trinidad-config.xml file in Jdeveloper editor and your will see like this



<skin-family>skin1</skin-family>

This means that skin1 is applied on Application

• now if you another ADF Skin file- skin2 then in trinidad-config.xml, it will be changed to



<skin-family>skin2</skin-family>



• ADF automatically choose the most recent skin, so here this is done , now create and configure your ADF Skin and customize appearance of application
• For more details see Oracle Docs- http://docs.oracle.com/cd/E16764_01/web.1111/b31973/af_skin.htm

ADF Basics : Implementing auto suggest behavior in ADF Faces lov (list of values)

Auto Suggest behavior is best understand by Google Instant, as in google when we type something and it starts showing suggestion instantly.

 This effect can be implemented in ADF using autoSuggestBehaviour
To use the auto-suggest functionality in a declarative way you need to define a model-driven list of values on your model project, which will be the base for the suggestedItems list. Select the Department Name attribute from the Department VO and create a List of Values. here i am using HR schema and predefined table Department to implement this

• Create a Fusion Web Application
• Now create EO and VO of Department table.(Business Components)





• Now create List of values(LOVs)on DepartmentName





• Create page in ViewController and drag the DepartmentName on page as ADF Lov ChoiceList or Lov Input
  


• Now go to Component Palette and select Auto Suggest Behaviour and drop it inside DepartmentName Lov
  
  
  
  


• Now select af:autoSuggestBehavior from Page structure and go to PropertyInspector and Open Expression Builder at SuggestedItems and select from bindings #{bindings.DepartmentName.suggestedItems} if you are using different tables and Lov select according to that








• Now run your page and enjoy autosuggest behavior (ADF Instant) 

Cheers :-) Happy Learning

Managed bean code to show multiline message in ADF using FacesMessage-

    package multilineMessages.view.bean;
     
    import javax.faces.application.FacesMessage;
    import javax.faces.context.FacesContext;
    import javax.faces.event.ActionEvent;
     
    public class MultilineMessageBean {
        public MultilineMessageBean() {
        }
     
        public void showMessage(ActionEvent actionEvent) {
            StringBuilder message = new StringBuilder("<html><body>");
            message.append("<p><b>Hi This is Frist Line--Oracle ADF Message</b></p>");
            message.append("<p><i>Hi This is Second Line--Oracle ADF Message</i></p>");
            message.append("<p><b>Hi This is Third Line--Oracle ADF Message</b></p>");
            message.append("</body></html>");
            FacesMessage fm = new FacesMessage(message.toString());
            fm.setSeverity(FacesMessage.SEVERITY_INFO);
            FacesContext fctx = FacesContext.getCurrentInstance();
            fctx.addMessage(null, fm);
        }
    }

To use for Error and Warning just change FacesMessage.SEVERITY_INFO to SEVERITY_ERROR or SEVERITY_WARN.
It will look like this
You can change your Message accordingly

 you can also use some html styles (CSS) to change color of text that appears in message body , see the changed code

    public void showMessage(ActionEvent actionEvent) {
        StringBuilder message = new StringBuilder("<html><body>");
        message.append("<p style='color:navy'><b>Hi This is Frist Line--Oracle ADF Message</b></p>");
        message.append("<p style='color:green'><i>Hi This is Second Line--Oracle ADF Message</i></p>");
        message.append("<p style='color:magenta'><b>Hi This is Third Line--Oracle ADF Message</b></p>");
        message.append("<p style='color:red'><b><i>This is Fourth line--Oracle ADF Message</i></b></p>");
        message.append("</body></html>");
        FacesMessage fm = new FacesMessage(message.toString());
        fm.setSeverity(FacesMessage.SEVERITY_INFO);
        FacesContext fctx = FacesContext.getCurrentInstance();
        fctx.addMessage(null, fm);
    }

now see the FacesMessage look like this-
