Do you know what is the use to have a doGet() method
inside a doPost() method in servlet like the
following?


public void doPost(HttpServletRequest req,
HttpServletResponse res)
throws ServletException,IOException
{
doGet(req,res);
}

Get and Post differ in the way server treats them and you can easily do
the same thing get does in post as long as you don't care. This servlet
responds similar to both post and get requests.

We use doGet() method  inside the doPost() method to go from DoPost method to DoGet method.

doGet() and doPost() are called in different
ocassions, when you call an URL you normally make a
GET request, when you put a form and set the <FORM
METHOD=POST> then you have a post request. Forms can
be either get or post, so to process a form request
yuou may program both methods or you mey loose some
requests
so, the easieste way is to call doPost() from doGet()
or viceversa or point both of them to your function.

you'd better override these two methods separately . but if you use nested forms or some several frames with separate forms(maybe each form has its own method), in your HTML tags you may need to impelemnting doGet() within doPost() method  .

This is the proposed default implementation in servlet  specification.
If for some reasons you need to handle these methods separately you
can override them.
