    Default jsp insert into database error(java.lang.NumberFormatException: For input string: "")

    Hi all,

    I am trying to insert data from a jsp form into a table when the user clicks the submit button. I am encountering this exception.

    java.lang.NumberFormatException: For input string: "type"

    Here is my code:

    This is the code in the form jsp:

    <select name="utype">
    <% try
    int type=(rs2.getInt(1));
    String strName1=rs2.getString(2);
    <option value="type">
    <%= strName1 %>
    catch(Exception e)


    this is my code in the sign - up bean:


    String firstName, lastName, address, city, state, email,userName, password, secAnswer;
    int zipcode, phoneNo, utype, squestion;

    firstName = request.getParameter( "firstName");
    lastName = request.getParameter( "lastName");
    address = request.getParameter( "address");
    city = request.getParameter( "city");
    state = request.getParameter( "state");
    zipcode = Integer.parseInt(request.getParameter( "zipcode"));
    email = request.getParameter( "email");
    phoneNo = Integer.parseInt(request.getParameter( "phoneNo"));
    userName = request.getParameter( "userName");
    password = request.getParameter( "password");
    utype = Integer.parseInt(request.getParameter( "utype"));
    squestion = Integer.parseInt(request.getParameter( "squestion"));
    secAnswer = request.getParameter( "secAnswer");

    db.insert(firstName, lastName, address, city, state, zipcode, email, phoneNo, userName, password, utype, squestion, secAnswer);

    and this is my dbBean's insert method:

    public void insert(String firstName, String lastName, String address, String city, String state, int zipcode, String email, int phoneNo, String userName, String password,int utype, int squestion, String secAnswer) throws SQLException {
    try {

    PreparedStatement pstmt = null;
    String queryString =
    "INSERT INTO UserAccountDetails1(username,firstname, lastname, address, city, statecode, zipcode, email, phonenumber, password, usertypecode, questioncode, answer, lastmodifieduser, lastmodifiedtime) values(?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)";

    pstmt = dbCon.prepareStatement(queryString);
    pstmt.setString(1, userName);
    pstmt.setString(2, firstName);
    pstmt.setString(3, lastName);
    pstmt.setString(4, address);
    pstmt.setString(5, city);
    pstmt.setString(6, state);
    pstmt.setInt(7, zipcode);
    pstmt.setString(8, email);
    pstmt.setInt(9, phoneNo);
    pstmt.setString(10, password);
    pstmt.setInt(11, utype);
    pstmt.setInt(12, squestion);
    pstmt.setString(13, secAnswer);
    } catch (SQLException sqlex) {
