How to get variables from a form?

How do I get variables from a form. I read devshed's article but now I am trying to go beyond what they have done and find out how I can get info from a form. Can someone give me a quick explanation or lead me to a place where I could learn how?

In order to get variables from your HTML form in your servlet you need to access the HTTPRequest object in your doGet or doPost method. I am assuming that you have some code like this:

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

In order to get the values that were entered into the form you need to use code like this in your doGet or doPost method:

String phone = req.getParameter("phoneNumber");

You will probably have different parameters, but you will just need to enter their names where I have used "phoneNumber". The name you pass to the getParameter() method needs to be the name you gave the field in your HTML form.

I hope that helps.
