How it could be possible for the Hello class. This class is not a servlet or anything that can process the request. Did you use any framework? It's just a simple java class and you didn't give the class any power to handle the request. To read the value you need to create a web application.

add a setter and getter method to the class, and in jsp try to use the hello class as bean, simply set the str var using setter and getter methods :D

use scriplet (i.e <%%>) for writing java code in jsp page

XML

<html
<body>
<form method="post">
<input type =text name="urltext">
<input type="Submit" name="btn" value="submit">
<%
String txtbox=request.getParameter("urltext");
String btn1=request.getParameter("btn");
if(btn1!=null)
{
    out.println(txtbox);
}

%>
</body>
</html>
