無法傳輸數據到mySQL數據庫

Question

我有一個signup.jag（jaggery頁）供用戶註冊。 我有一個signup.js（javascript）爲javascript驗證。

我想存儲在MySQL數據庫通過Java JDBC即針對我寫與文件名下面的代碼sigunp.java用戶信息：

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

public class signupdb extends HttpServlet 
{ 
    public void doPost(HttpServletRequest request,HttpServletResponse response)throws ServletException IOException 
    { 
      response.setContentType(text/html); 
      PrintWriter pw = response.getWriter(); 

      String connectionURL = "jdbc:mysql://localhost:3306/ticketing"; 
      Connection connection; 
      try 
      { 
        String firstname = request.getParameter("fname"); 
        String lastname = request.getParameter("lname"); 
        String phonenum = request.getParameter("phone"); 
        String addr = request.getParameter("address"); 
        String email = request.getParameter("email"); 
        String password = request.getParameter("pass"); 

        pw.println(firstname); 
        pw.println(lastname); 
        pw.println(phonenum); 
        pw.println(addr); 
        pw.println(email); 
        pw.println(password); 

        Class.forName("com.mysql.jdbc.Driver"); 
        connection = DriverManager.getConnection(connectionurl,"root","suselinux"); 
        PreparedStatement pst = connection.prepareStatement("insert into userinfo values(?,?,?,?,?,?)"); 
        pst.setString(1,firstname); 
        pst.setString(2,lastname); 
        pst.setString(3,phonenum); 
        pst.setString(4,addr); 
        pst.setString(5,email); 
        pst.setString(6,password); 

        int i = pst.executeUpdate(); 

        if(i != 0) 
        { 
          pw.println("<br>Record has been inserted"); 
        } 
        else 
        { 
          pw.println("No Data Inserted"); 
        } 
      } 
      catch(Exception e) 
      { 
        pw.println(e); 
      } 
    }  
} 

但是當我開始jaggery服務器並提交了它顯示的數據錯誤404。

終於我解決了！

我創建了一個con.jag文件具有表命名用戶：

<% 

var query1 = "create table users (id int not null auto_increment, primary key(id), first_name varchar(15), last_name varchar(15), phone varchar(20), address varchar(50), email varchar(30), pass varchar(30));"; 


config(); 

var db = new Database ("jdbc:mysql://localhost:3306/tickets", "root", "password", config); 

try 
{ 
     db.query(query1); 
     print("Table Created again"); 
} catch (e) 
     { 
       print(e.toString()); 
     } 
     finally 
       { 
         db.close() 
       } 
%> 

然後用insert_data .jag文件插入的數據到數據庫中：

<% 

var frst_name = request.getParameter('fname'); 
var lst_name = request.getParameter('lname'); 
var country_name = request.getParameter('country_code'); 
var phon = request.getParameter('phone'); 
var addr = request.getParameter('address'); 
var mail = request.getParameter('email'); 
var pwd = request.getParameter('pass'); 

var data = "insert into users(first_name, last_name,country, phone, address, email, pass) values ('"+frst_name+"','"+lst_name+"','"+country_name+"', '"+phon+"','"+addr+"','"+mail+"','"+pwd+"')"; 



config(); 
var db = new Database ("jdbc:mysql://localhost:3306/tickets", "root", "password", config); 

try 
{ 
     db.query(data); 
} catch(e) 
     { 
       print(e.toString()); 
     } finally 
       { 
         db.close() 
       } 
%> 

它真的很好！
