How to use FacesMessage in ADF

FacesMessage is used to show confirmation, warning, information .In this tutorial, you will see that how to use FacesMessage to show any information, warning or any error. Suppose you want to show a confirmation when you save your records, here we use FacesMessage.

Managed Bean Code to use FacesMessage(Information)-

      FacesMessage Message = new FacesMessage("Record Saved Successfully!");   
      Message.setSeverity(FacesMessage.SEVERITY_INFO);   
      FacesContext fc = FacesContext.getCurrentInstance();   
      fc.addMessage(null, Message);   

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

Those who are familiar with Oracle ADF can create basic architecture of MVC.

So follow these steps

• Create a Fusion Web Application in Jdeveloper(IDE)

• and Write this code on button

public void showMessageButton(ActionEvent actionEvent) {
 FacesMessage msg=new FacesMessage("This is an inline FacesMessage");
 msg.setSeverity(FacesMessage.SEVERITY_FATAL);
 FacesContext fctx=FacesContext.getCurrentInstance();
 fctx.addMessage(null, msg);
