Show current Date and Time on Page in Oracle ADF (refresh Date/time Programmatically)

This tutorial i am going to explain that how to show current date and time on your ADF application page
Follow Steps-

• Create a fusion web application and a page in it (i have used .jspx page)
• Now drag an output text from component palette and drop it on page

• Now select the output text and go to its property inspector then select value from Expression Builder as shown in image

• Now in Expression Builder ,create a Managed Bean of type java.util.Date and assign its value to output text

•  Now run your page and see current date is there

• Now to format Date and Time , drag and drop af:convertDateTime  under output text from component palette

•  Select convertDateTime and go to property inspector and change its pattern and run your page

•  Now you have done basic configuration for Date/Time, if you want to refresh time (second and minute part) on page periodically then drop a poll component in page and create a poll listener in managed bean

• Now write this simple code in your managed bean to invoke poll listener



    /**Binding of Output text*/
    private RichOutputText dateBind;

    public void setDateBind(RichOutputText dateBind) {
        this.dateBind = dateBind;
    }

    public RichOutputText getDateBind() {
        return dateBind;
    }

    protected void refreshPage() {
        FacesContext fctx = FacesContext.getCurrentInstance();
        String refreshpage = fctx.getViewRoot().getViewId();
        ViewHandler ViewH = fctx.getApplication().getViewHandler();
        UIViewRoot UIV = ViewH.createView(fctx, refreshpage);
        UIV.setViewId(refreshpage);
        fctx.setViewRoot(UIV);
    }


    /**Poll Listener Method ,handles Poll Event
     * @param pollEvent
     */
    public void refreshTime(PollEvent pollEvent) {
        refreshPage();
        AdfFacesContext.getCurrentInstance().addPartialTarget(dateBind);

    }



• Now Run your application , see in this video clip how your page get refreshed... Cheers ..!
