Writing to a text file

I need to know how i can capture the user input and then write to a text file. Currently, the form page is saved as Adhoc.jsp, which means that the form page uses jsp to retrieve some information from the database.

*Note: i just need to know how i can capture the user input and then write to a text file.

Pls help asap...........

Use a bean to do the file writing as in:

<%@ page language="java" contentType="text/html" import="java.util.*" %>
<%@ page errorPage="errorPage.jsp" %>

<html>

<head>
<title>RequestWriter</title>
</head>
<body bgcolor="#669966" >
<jsp:useBean id="writer" scope="page" class="utilities.RequestWriter" />
<jsp:setProperty name="writer" property="*"/>
<%

String password = request.getParameter("password");

if (writer.isCorrectPassword(password)) {
writer.save();
out.println("<h2 align=\"center\">Changes saved</h2>");
}else{
out.println("<h2 align=\"center\">Incorrect Password</h2>");
}

%>

<form action="index.jsp" method="get">
<center><input type="submit" value="Go to Home Page"/></center>
</form>

</body>
</html>
