ADF Utility : Find UIComponent from Managed Bean

Many a times, it is required to find an UIComponent from ADF managed bean, to do something with it, for example : change the value of an af:outputText, change readOnly property of an af:inputText etc.

    private UIComponent getUIComponent(String id) { 
       
        FacesContext facesCtx = FacesContext.getCurrentInstance(); 
        return findComponent(facesCtx.getViewRoot(), id);
    } 
   
    private UIComponent findComponent(UIComponent base, String id) {
       
        if (id.equals(base.getId())) {
            return base;
        }

        UIComponent children = null;
        UIComponent result = null;
        Iterator childrens = base.getFacetsAndChildren();
        while (childrens.hasNext() && (result == null)) {
            children = (UIComponent)childrens.next();
            if (id.equals(children.getId())) {
                result = children;
                break;
            }
            result = findComponent(children, id);
            if (result != null) {
                break;
            }
        }
        return result;
    }


This will search from the UI view root for all elements until it finds the UIComponent of the same ID.

NOTE : This is widely available in ADF community, I just wanted to make this available for those we are only looking for this utility.

Secure your Node/Express REST APIs using Passport JS

Recently I have been involved in various discussions on how to make the REST APIs as secure as SOAP.
First of all, let me start with a very basic statement, about security, it doesn't depend on your Webservice type, be it REST or SOAP, your design decisions depicts whether they can be made secure or not.
In this example blog, I will use "Micro CRUD services for Oracle Database Cloud" APIs and implement (read attach) Passport's "local" authentication strategy, to make them secure.

Code in Github : LeasifyAPIs with Passport

What is Passport JS? (from Documentation)

Passport is authentication middleware for Node. It is designed to serve a singular purpose: authenticate requests. When writing modules, encapsulation is a virtue, so Passport delegates all other functionality to the application. This separation of concerns keeps code clean and maintainable, and makes Passport extremely easy to integrate into an application.

Chatbots and Oracle Cloud Services

Thanks to Oracle A-Team, I had a chance to work with Chatbots.
3 pure NodeJS applications, on couple of Oracle Cloud platforms and Facebook messenger, and my chatbot was running.

Let me explain, the architecture a bit. To start with, following is the simple representation of how it works.
