modify servlet context init parameter(<context-param>) values

I am going through one web development process in which, I have two parameters say username and password as context parameters in web.xml file like:- 

<context-param>
    <param-name>uname</param-name>
    <param-value>demouser</param-value>
    </context-param>
    <context-param>
    <param-name>pwd</param-name>
    <param-value>demopwd</param-value>
    </context-param>

One of my servlet is getting the uname and pwd field by getServletContext.getgetInitParameter("uname"); and simillarly the pwd field,

Now at some point of time, I want to change the values of context parameters through same servlet or other. How to do that. Please help me out by few suggestions.

Thanks & Regards, Ars.

You cant modify context parameters directly, but you could use ServletContextListener implementation to keep and modify all the necessary variables and objects. See http://docs.oracle.com/javaee/5/tutorial/doc/bnafi.html for details.
