hi,
I am calling the post method of the servlet with the following url
<form name=frm1 method=post action="..?aa=12&bb=13">
<input type=hidden name=hid1 value=10>
</form>
in the called servlet i am able to retrieve all the parameters how is this happening.
Also if i try to do it using get then the values are overwritten and only vaue of hidden variable is obtained.
bye

when you 'post' data, it uses a separate stream. So both the querystring you have built in the action tag, and the posted form data will make it to the servlet.

when you 'get' data, then only a query string is sent. I have not tried it out, but from what you are saying, it appears that the querystring is overwritten by your browser, and so it ignores the querystring already written in the action tag.

In GET, the query string is appended to the end of the requested URL. In POST, the parameters are sent within the body of request in a urlencoded format.
 
It is sorta covered in the JavaRanch Style Guide.
