Defining validation in the ADF View Layer

ADF framework provides ADF Faces validation to add validation rules to an ADF Faces component.

A “validator” attribute is used to create business specific validation rule.

Validator uses el expression to bind method in a managed bean. In this Example, I will explain how to build your own custom validation logic. This example is based on HR schema Employees table and our business rule in phone_number attribute must be 10 digits.

  1. Open managed bean class and create method with following method signature.
    public void methodName(FacesContext, UIComponent, Object){...}
                     public void validatePhoneNo(FacesContext facesContext, UIComponent uIComponent, Object value) {  
        String pno=value.toString();
        FacesMessage message = new FacesMessage(FacesMessage.SEVERITY_ERROR,null,"Phone Number must be 10 digits");
        throw new ValidatorException(message);
  2. In your inputText component bind validator attribute with above managed bean validatePhoneNo method.
