Switching ADF Skin at run time using trinidad-config.xml

Sharing is Caring

This post talks about switching ADF skin at runtime and uses a managed bean variable to change skin name at runtime. Sometimes we want to use multiple themes for our application and in that case, we need this.

Created an ADF application, 2 different skins and a page in view controller project

This page has a button to switch between skins and an outputText. Create a variable in the managed bean to hold skin name and button action listener to change skin variable value.

Here goes the managed bean code

package switchadfskin.view.bean;

import javax.faces.application.ViewHandler;
import javax.faces.component.UIViewRoot;
import javax.faces.context.FacesContext;
import javax.faces.event.ActionEvent;

public class SwitchADFSkinBean {
    public SwitchADFSkinBean() {

    //Set default skin name
    private String skinName = "RedButton";

    public void setSkinName(String skinName) {
        this.skinName = skinName;

    public String getSkinName() {
        return skinName;

    /**Method to change skin at runtime
     * @param actionEvent
    public void switchSkinAction(ActionEvent actionEvent) {
        //Change skin name
        if (skinName.equalsIgnoreCase("RedButton")) {
        } else {
        //Reload page

    /**Method to refresh/reload page
    protected void refreshPage() {
        FacesContext fctx = FacesContext.getCurrentInstance();
        String page = fctx.getViewRoot().getViewId();
        ViewHandler ViewH = fctx.getApplication().getViewHandler();
        UIViewRoot UIV = ViewH.createView(fctx, page);


The next step is to change trinidad-config.xml file, set skin-family variable to refer its value from managed bean so that when the user changes bean variable then skin (CSS) is updated in the application.

<?xml version="1.0" encoding="windows-1252"?>
<trinidad-config xmlns="http://myfaces.apache.org/trinidad/config">

Now run and check application

The default skin is “RedButton” so it looks like this

and on click of the button
