Hi Friend,

Try the following code:

1)form.jsp:

<form name="form" method="post" action="../Servlet" >
Enter Name:<input type="text" name="textname"><input type="submit" value="submit">
</form>

2)Servlet.java:

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

public class Servlet extends HttpServlet {
public void doPost(HttpServletRequest request, HttpServletResponse response)throws IOException, ServletException{
PrintWriter out = response.getWriter();
String name=request.getParameter("textname");
response.sendRedirect("./modified/action.jsp?name="+name);
}
}

3)action.jsp:

<form name="form" method="post" action="../ServletExample" >
<table>
<tr><td>Enter Address:</td><td><input type="text" name="textaddress"></td></tr>
<tr><td>Enter Email:</td><td><input type="text" name="textemail"></td></tr>
<tr><td>Enter Contact No:</td><td><input type="text" name="textcontact"></td></tr>
<tr><td><input type="submit" value="submit"></td></tr>
</table>
<input type="hidden" name="textname" value="<%=request.getParameter("name")%>">
</form>

4)ServletExample.java:

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

public class ServletExample extends HttpServlet{
public void doPost(HttpServletRequest req,HttpServletResponse res)throws ServletException,IOException{
PrintWriter out=res.getWriter();
String name=req.getParameter("textname");
String address=req.getParameter("textaddress");
String email=req.getParameter("textemail");
String contact=req.getParameter("textcontact");
out.println(name+" "+address+" "+email+" "+contact);
}
}

Hope that it will be helpful for you.
Thanks
