How can we put jsp or javascript code in java code on jsp

How can we pass the input of jsp page on the java code in the same jsp?

for e.g. I want to put value of Gender field from the jsp into the java Variable gender.

document.form[0].gender.value

<%
String gender = document.form[0].gender.value;
%>

Thanks and Regards

You don't: the Java has executed before it gets to the client.

Hi Ravinder,

Javascript will be executed at client side ( Browser) while scriplet ( i.e java code written in jsp ) will be executed at the server side. I don't know, what you are trying to achieve here.. May be you should explain your problem in detail...
