JSP代码：

    <%@ page import="java.sql.*" %>
    <%@page contentType="text/html" pageEncoding="UTF-8"%>
    <!DOCTYPE html>
    <html>
        <head>
            <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
            <title>JSP Page</title>
        </head>
        <body>
            <%
                if (!"POST".equalsIgnoreCase(request.getMethod())) {
            %>
            <h1>Invalid Token!</h1>
            <%
                } else {
                    Connection connection = null;

                    String[] arr = new String[18];
                    arr[0]   = (request.getParameter("ignoualr")!=null)?request.getParameter("ignoualr").toString():"0";
                    arr[1]   = request.getParameter("enrlno").toString();
                    arr[2]   = request.getParameter("firstname").toString();
                    arr[3]   = request.getParameter("middlename").toString();
                    arr[4]   = request.getParameter("lastname").toString();
                    arr[5]   = request.getParameter("ffirstname").toString();
                    arr[6]   = request.getParameter("fmiddlename").toString();
                    arr[7]   = request.getParameter("flastname").toString();
                    arr[8]   = request.getParameter("dob").toString();
                    arr[9]   = (request.getParameter("sex")!=null)?request.getParameter("sex").toString():"0";
                    arr[10]   = request.getParameter("progc").toString();
                    arr[11]   = request.getParameter("address").toString();
                    arr[12]   = request.getParameter("state").toString();
                    arr[13]   = request.getParameter("city").toString();
                    arr[14]   = request.getParameter("district").toString();
                    arr[15]   = request.getParameter("pincode").toString();
                    arr[16]   = request.getParameter("mobileno").toString();
                    arr[17]   = request.getParameter("submit").toString();    

                    if(arr[17].equalsIgnoreCase("Submit")) {
                        Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
                        connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/emp", "root", "");

                        Statement statement = connection.createStatement();
                        String command = "INSERT INTO registration (id, ignoualr, enrlno, firstname, middlename, lastname, ffirstname, fmiddlename, flastname, dob, sex, progc, address, state, city, district, pincode, mobileno) VALUES (null";

                        for (int i=0; i<17; i++)
                            command = command + ", '" + arr[i] + "'";
                        command = command + ")";
                        statement.executeUpdate(command);
            %>
            <h1>Hello World!</h1>
            <%
                    } else {
            %>
            <h1>Invalid Token!</h1>
            <%
                    }
                }
            %>
        </body>
    </html>

另外，我将 mysql-connector-java-5.0.8.zip 添加到项目的libraries文件夹中。
附：我有java的基本知识和PHP的工作知识。

您加载了错误的驱动程序。

变化：

Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");

为：

Class.forName("com.mysql.jdbc.Driver");

如何修复＆＃34;没有为jdbc找到合适的驱动程序：mysql：// localhost：3306 / emp＆＃34;？
