When your JSP/Servlet receives a set of the HTTP request parameters, it is common to call:
* HttpServletRequest.getParameters(String name)
(or its variants) for your JSP/Servlet to get their values. Because the HTTP request parameters are sent in the form of URL-encoded String, the above method includes the repeated conversion between the String and byte arrays behind the scene. But, as you know, the JSP/Servlet specification (at least, up to Version 2.4) does not define the methods to get the request parameters in the intermediate stage. Because only the request parameters in the form of the decoded String (that is the original String) are human readable, we tend to think that we always need them. But, in fact, it is not always true. There are the cases that the URL-encoded String or the byte arrays are enough. This Java API implements the methods for getting the request parameters in any stage.
