Right click on the file in eclipse an go to properties, you'll see that this is a different file.

Actually you should not try to write/create a file in such a location. Your application may not always be unpacked from a .war archive, in which case ServletContext#getRealPath() will return null.

An alternative would be to define a context init parameter in your web.xml and set a root for the file system that should be visible to your application

    fsroot
    E:\CodePractice

and to retrieve it anywhere (servlets/JSPs) in your application you can use ServletContext#getInitParameter(java.lang.String):

String path = getServletContext().getInitParameter("fsroot");
