<sql:setDataSource var="snapshot" driver="com.mysql.jdbc.Driver"
     url="jdbc:mysql://localhost:3306/mydb"

<sql:query dataSource="${snapshot}" var="result">
SELECT * from dateinfo;

<table border="1" width="100%">
<tr>
<th>Emp ID</th>
<th>First Name</th>
<th>Last Name</th>
<th>Age</th>

<c:forEach var="row" items="${result.rows}">
<tr>
<td><c:out value="${row.id}"/></td>
<td><c:out value="${row.first}"/></td>
<td><c:out value="${row.last}"/></td>
<td><c:out value="${row.age}"/></td>
</tr>
</c:forEach>
</table>

当我执行此程序时发生异常....

    javax.servlet.ServletException: javax.servlet.jsp.JspException: Unable to get 
connection, DataSource invalid: "java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/mydb"

即使我可以在我的netbeans中包含mysqlconnector.jar,jstl.jar and standard.jar文件项目还加上所有的解放，请帮帮我......

任何帮助都将受到高度赞赏

jstl与数据库连接
