Question

Hello,
I'm having a small trouble. Here is the problem.
I have a jsp page, which I used to enter data. There is a textbox called nicno. Now I want to verify that, if a user enter a valid nicno or not.
Here is the .jsp page which I use to enter data.
<form method="POST" action="FinalCtrl.jsp">
  <div align="center">
    <center>
    <table border="1" cellpadding="0" cellspacing="0" style="border-collapse: collapse"

        details.....</b></td>

In order to do this I wrote a javaBean called ApproveMgr.java
package hrm;
import java.io.*;
import java.sql.*;
import java.util.*;
import javax.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class ApproveMgr
     private  String DRIVER = "com.mysql.jdbc.Driver";
       private  String URL = "jdbc:mysql://localhost:3306/super";
     private  Connection connection;
        private  PreparedStatement pstmt1;
        private String nicno;
        private String interviewDateM;
        private int interviewDateD;
        private int interviewDateY;
       // Constructor
     public ApproveMgr()
          this.nicno = nicno;
          this.interviewDateM = interviewDateM;
          this.interviewDateD = interviewDateD;
          this.interviewDateY = interviewDateY;
   * Returns the nicno.
   public String getNicno()
      return nicno;
   * Sets the nicno.
   public void setNicno(String nicno)
      this.nicno = nicno;
   * Returns the interviewDateM.
   public String getInterviewDateM()
      return interviewDateM;
   * Sets the interviewDateM.
   public void setInterviewDateM(String interviewDateM)
     this.interviewDateM = interviewDateM;
   * Returns the interviewDateD.
   public int getInterviewDateD()
      return interviewDateD;
   * Sets the interviewDateD.
   public void setInterviewDateD(int interviewDateD)
     this.interviewDateD = interviewDateD;
   * Returns the interviewDateY.
   public int getInterviewDateY()
      return interviewDateY;
   * Sets the interviewDateY.
   public void setInterviewDateY(int interviewDateY)
     this.interviewDateY = interviewDateY;
     // Initializes the connection and statements
        public void initConnection() {
                if (connection == null) {
             try {
                      String sql;
                      // Open the database
                      Class.forName(DRIVER).newInstance();
                      connection = DriverManager.getConnection(URL);
                      //Verify nicno
                      sql="SELECT nicNo FROM Approve where nicNo= ?";          
               pstmt1 = connection.prepareStatement(sql);
         catch (Exception ex) {
            System.err.println(ex.getMessage());
     public boolean verifyNicNo(){
          boolean nic_no_select_ok = false;
          String nic="xxxx";
          initConnection();
                try {
                   pstmt1.setString(1, nicno);
               ResultSet rs1 = pstmt1.executeQuery();               
                            if(rs1.next()){
                    nic=rs1.getString("nicNo");
                           if(nic.equals("xxxx"))
                    nic_no_select_ok = true;
               } else{
                    nic_no_select_ok = false;     
               rs1.close();
                       pstmt1.close();
                catch (Exception ex) {
                  System.err.println(ex.getMessage());
          return nic_no_select_ok;
Here is my problem. In my table Approve it has the following record.
Approve(810000000V,January,02,2004)
When I go to the form and enter the data and clicks to the Approve button it always displays the
error page "Invalid nicno".
This error page displays when I enter a nicno which is already exists or not. It should be
display only for invalid number.(which does not exist in Approve table) only. But it dosen't do like that. Please, can somebody tells me whats going on.
Thanks.

Answer 1

Try calling approve.setNicno(......); before approve.verifyNicno()I think that should do it...
