<%@ page language="java" %>
<%@ page import="EmpBean" %>
<jsp:useBean id="user" class="EmpBean" scope="session">
<jsp:setProperty name="user" property="*"/>
</jsp:useBean>
<html>
<body>
<form method=post action=/abacus/servlet/SampleServlet>
<input type="text" name="empcode"><br>
<input type="text" name="empname"><br>
<input type="submit" value="submit">
</form>
</body>
</html>
I have the above jsp page which is submitted to the SampleServlet. How to pass the bean object "user" which is set in the Jsp to the servlet?

I don't see any reason why your servlet should'nt be able to access the said bean like any other regular class. Just use the beans instance to access the properties you had set using the JSP.

Hi Mukund,
u have defined the scope of the bean as session in the jsp hence in the servlet u can access it from the seeion object by using
EmpBean e = (EmpBean)session.getAttribute("user");

Problem: you don't have the bean class in a package.

You will waste a lot of time chasingn weird errors if you don't put the bean class in a package. In addition to using the package name in the useBean tag:

you will have to import the package in both the JSP and the servlet.
