Question

我写这段代码并有错误代码：

<%@ page import="java.io.*,java.util.*,java.sql.*"%>
<%@ page import="javax.servlet.http.*,javax.servlet.*" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/sql" prefix="sql"%>

<html>
    <head>
        <title>Adib Test</title>
    </head>
    <body>
        <sql:setDataSource  var="snapshot"
                           url="jdbc:mysql://localhost:3306/test"
                           user="root"
                           driver="com.mysql.jdbc.*"
                           password="ad-09139297791+ib"/>

        <sql:query dataSource="${snapshot}" var="result">
            SELECT * from test
        </sql:query>
            <table border="1" width="100%">
<tr>
<th>Emp ID</th>
<th>First Name</th>
</tr>
<c:forEach var="row" items="${result.rows}">
<tr>
<td><c:out value="${row.user}"/></td>
<td><c:out value="${row.pass}"/></td>
</tr>
</c:forEach>
</table>

</body>
</html>

</html>

错误

HTTP状态500 - 在第11行处理JSP页面/index.jsp时发生异常

输入例外报告

message在第11行处理JSP页面/index.jsp时发生异常

说明服务器遇到内部错误，导致无法完成此请求。

例外

org.apache.jasper.JasperException：在第11行处理JSP页面/index.jsp时发生异常

8:         <title>Adib Test</title>
9:     </head>
