Take a look at the documentation for HttpServletRequest.
In order to build the URL in your example you will need to use:

• getScheme()
• getServerName()
• getServerPort()
• getContextPath()

Here is a method that will return your example:

public static String getURLWithContextPath(HttpServletRequest request) {
   return request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + request.getContextPath();
}
