How to access same ServletContext object in another servlet?

I have written demo program for ServletContext object, in which I am setting value by using context.setAttribute(arg1,arg2). and I want to access same object in another servlet. how can I access the value set by context object ,in another servlet.

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

    response.setContentType("text/html");
    PrintWriter out = response.getWriter();

    String name = "Amrut";

    ServletContext context = request.getServletContext();

    context.setAttribute("contextuname", name);

    out.println("Context==>" + context.getAttribute("contextuname"));
}

my question is, for accessing this object i have to create ServletContext object and by using context.getAttribute(arg1,arg2) ,will i get value. or there is another value to do this.

In service(doGet/doPost) method of another servlet in same application, do this

ServletContext context = request.getServletContext();

String uName = (String)context.getAttribute("contextuname");

As per the Java doc 

 There is one context per "web application" per Java Virtual Machine.

So your Context Object will be available for all the servlets. and the attributes inside context object will also.

my question is, for accessing this object i have to create ServletContext object

It will return the same context object, it will not create a new object

You will get value by creating context object same as above in the another servlet.
According to java docs

There is one context per "web application" per Java Virtual Machine.
