Where does this parameter come from ? Did you post the parameter from an html form, or via the URL ?

It sounds like a servlet question. There is a servlets forum where you can ask this kind of question.

Parameters in a request are set by the HTML client when the request is created, typically form elements (input and file elements to be exact) within a HTML form. Therefore if the form that called your servlet/JSP page had an element with a name "chennai", you would retrieve the value of that form element by using getParameter("chennai").

Actually here i am using asterisk and this request.getParameter wii retreive the data from the asterisk.if a person calls from chennai,it will be displayed in the asterisk console like

from this console i have to get the parameter chennai.neither servlet or jsp is used here.but i am not getting the parameter eventhough i hardcoded the parameter.thats why i am confused why it is displaying null even the string i have passed is chennai directly.
