Introduction
In this tutorial, we will learn how to add HTTP basic authorization token to the HTTP request header.
We will use Jersey Framework to consume RESTful web services. Read the following post if you want to learn how to secure web services using HTTP Basic Authentication
Jersey Java Framework - How to add HTTP Basic Authentication to RESTful web services?

Basic Authentication
is the most simple way to secure HTTP requests. It has the following format
Authorization: Basic base64-encoding of username:password
Jersey Client
Jersy is the reference implementation of JAX-RS. JAX-RS makes it very easy for Java developers to develop and consume RESTFul web services.
There are different ways To add basic authorization token to HTTP request, we will cover the following two ways
