doGet v/s doPost

>>but, when i replaced   doGet(request,response); with  doPost(request,response);


Are you effectively saying all you did was change the letters 'Get' to 'Post'?

doGet handles get requests, doPost handles post requests.

if you want to handle both the same then have doGet() call doPost() (as it appears you have done)

The stack overflow would be caused by a method calling itself.

yes, all i did was to change get to post

then that sounds fine.

>>yes, all i did was to change get to post

I can't think of a reason offhand why that in itself would cure a stack overflow

what is exactly meant by doPost() in servlets?
I am little confused. As i was reading comments from One expert, he said that doPost() is like posting information to the server(secure information like credit cards..ect).

If we are posting information to the server , why is it written in the servlet??

and as i understand, doGet() is getting information from the server..

any advice appreciated.

thanks

See my earlier comment, doGet is for handling get requests ie. using get method, and post is for post requests

eg.

<form method="get" action="MyServlet">

when this is submitted the doGet() will be called

<form method="post" action="MyServlet">

when this is submitted the doPost() will be called

the get method includes the parameters in the url of the request,
whereas the post method sends them seperately

ok,,i got it objects.
now for instance , i have written an application which has front end in swing. The objective of this front end is to communicate with the server and access the files in the server.

now , this is the servelt which is accessed by swing front-end. This servlet contains doPost() which has the main functionality. It also has doGet() which contains doPost(request,response);

do you have any reason why doPost() and doGet() are both used in this servlet.
