Can you explain your question more clearly. I don't think anyone can understand what you exactly want.

Keep in mind that this is a forum, not a code bank lol.

awkei...,

this a my web page, for instance...these are the fields that nids to be filled up..

Student information

Student No:

First Name:

Middle Initial:

Last Name:

City:

Province:

then there is a command button here named "submit".. when i click this submit button, automatically, the inputted information above will be displayed on the next page...

Did you get any error message? If so copy-pate here to see.

[jhen]

there's no error... the problem is when i click the submit button, it doesn't turn on the next page...


here is the code, i used java servlet for creating session...


package myBean;

import java.io.IOException;
import java.sql.SQLException;

import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;


public class MyServlet extends javax.servlet.http.HttpServlet implements javax.servlet.Servlet {

HttpSession session;
private MyBeanssss sessionbean;
RequestDispatcher dispatcher;
private String go;

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
{
doPost(request, response);
}


protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
{
session=request.getSession(true);
if(session!=null)
{
sessionbean=(MyBeanssss)session.getAttribute("bean _id");
go=(String)session.getAttribute("1stPage.jsp");
}
if (sessionbean!=null)
{
if(request.getParameter("btnSubmit")!=null){
sessionbean.setStudentNo(request.getParameter("stu dentNo")!=null? request.getParameter("StudentNo"): "");
sessionbean.setFname(request.getParameter("Fname") !=null? request.getParameter("Fname"): "");
sessionbean.setMI(request.getParameter("MI")!=null ? request.getParameter("MI"):"");
sessionbean.setLName(request.getParameter("LName") !=null? request.getParameter("LName"):"");
sessionbean.setCity(request.getParameter("City")!= null? request.getParameter("City"):"");
sessionbean.setProvince(request.getParameter("Prov ince")!=null? request.getParameter("Province"):"");
go="2ndPage.jsp";
}
else if (request.getParameter("btnBack")!=null){
go="1stpage";
}
else if(request.getParameter("Save")!=null){
doGetFormEntries(request);
try
{
sessionbean.doSave();
}catch (SQLException e)
{
e.printStackTrace();
}
go="1stPage.jsp";
}
else if(sessionbean!=null)
{
if (request.getParameter("btnCancel")!=null){
sessionbean.setStudentNo("");
sessionbean.setFname("");
sessionbean.setMI("");
sessionbean.setLName("");
sessionbean.setCity("");
sessionbean.setProvince("");
go="1stpage.jsp";

}
else
{
sessionbean=new MyBeanssss();
sessionbean.setStudentNo("");
sessionbean.setFname("");
sessionbean.setMI("");
sessionbean.setLName("");
sessionbean.setCity("");
sessionbean.setProvince("");
}
}
}
session.setAttribute("bean_id", sessionbean);
session.setAttribute("1stPage.jsp", go);

dispatcher=request.getRequestDispatcher(go);
dispatcher.forward(request,response);
}



private void doGetFormEntries(HttpServletRequest request)
{
sessionbean.setStudentNo(request.getParameter("Stu dentNo"));
sessionbean.setFname(request.getParameter("fname") );
sessionbean.setMI(request.getParameter("MI"));
sessionbean.setLName(request.getParameter("lname") );
sessionbean.setCity(request.getParameter("city"));
sessionbean.setProvince(request.getParameter("prov ince"));
}






}



this is the bean but i think there,s no problem here:

package myBean;


import java.sql.ResultSet;
import java.sql.CallableStatement;
import java.sql.SQLException;
import java.sql.Connection;

import my_common.*;
import my_common.DbConnector;


public class MyBeanssss
{
private Connection conn;
private CallableStatement cstmnt;

private String currentPage;

private String StudentNo="";
private String Fname="";
private String MI="";
private String LName="";
private String City="";
private String Province="";


public void doSave() throws SQLException
{
String sql= "{call sample_proc (?,?,?,?,?,?)}";//connection with database

conn=my_common.DbConnector.getConnection();
cstmnt = conn.prepareCall(sql);

cstmnt.setString(1, this.getStudentNo());
cstmnt.setString(2,this.getFname());
cstmnt.setString(3,this.getMI());
cstmnt.setString(4,this.getLName());
cstmnt.setString(5,this.getCity());
cstmnt.setString(6,this.getProvince());

cstmnt.executeUpdate();
}

public String getStudentNo() {
return StudentNo;
}
public void setStudentNo(String studentNo) {
StudentNo = studentNo;
}

public String getCity() {
return City;
}
public void setCity(String city) {
City = city;
}
public String getFname() {
return Fname;
}
public void setFname(String fname) {
Fname = fname;
}
public String getLName() {
return LName;
}
public void setLName(String name) {
LName = name;
}
public String getMI() {
return MI;
}
public void setMI(String mi) {
MI = mi;
}
public String getProvince() {
return Province;
}
public void setProvince(String province) {
Province = province;
}

public Connection getConn() {
return conn;
}
public void setConn(Connection conn) {
this.conn = conn;
}
public CallableStatement getCstmnt() {
return cstmnt;
}
public void setCstmnt(CallableStatement cstmnt) {
this.cstmnt = cstmnt;
}

public String getCurrentPage() {
return currentPage;
}
public void setCurrentPage(String currentPage) {
this.currentPage = currentPage;
}


}
