Hello Friend,

Try this:

1)EmpBean.java:

package form;
import java.util.*;
public class EmpBean {
private String name="rose";
private String address="Delhi";
private int contactNo=111111;
private String email="[email protected]";

public void setName(String name) {
this.name = name;
}
public String getName() {
return name;
}
public void setAddress(String name) {
this.address = address;
}
public String getAddress() {
return address;
}
public void setContactNo(int contactNo) {
this.contactNo = contactNo;
}
public int getContactNo() {
return contactNo;
}
public void setEmail(String email) {
this.email = email;
}
public String getEmail() {
return email;
}
public List dataList(){
EmpBean b=new EmpBean();
ArrayList list=new ArrayList();
list.add(b.getName());
list.add(b.getAddress());
list.add(b.getContactNo());
list.add(b.getEmail());
return list;
}
}

2)BeanInServlet.java:

import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class BeanInServlet extends HttpServlet{
    protected void doGet(HttpServletRequest req, HttpServletResponse res)
        throws ServletException, IOException{
        form.EmpBean p = new form.EmpBean();
        List list=p.dataList();

        req.setAttribute("data", list);
        RequestDispatcher rd = req.getRequestDispatcher("/jsp/beandata.jsp");
        rd.forward(req, res);
    }
}

3)beandata.jsp:

<%@page language="java" import="java.util.*" %>
<html>
<body> 
<table border="1" width="303">
<tr>
<td width="119"><b>Name</b></td>
<td width="168"><b>Address</b></td>
<td width="119"><b>Contact no</b></td>
<td width="168"><b>Email</b></td>
</tr>
<%Iterator itr;%>
<% List data= (List)request.getAttribute("data");
for (itr=data.iterator(); itr.hasNext(); ){
%>
<tr>
<td width="119"><%=itr.next()%></td>
<td width="168"><%=itr.next()%></td>
<td width="168"><%=itr.next()%></td>
<td width="168"><%=itr.next()%></td>
</tr>
<%}%>
</table>
</body>
</html>

Thanks
