<%@ page language="java" import="java.util.*,java.sql.*" pageEncoding="ISO-8859-1"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<%
Class.forName("com.mysl.jdbc.Driver");
Connection con=java.sql.DriverManager.getConnection("jdbc:mysql://localhost:3306/student","root","root");
Statement stmt=con.createStatement();
ResultSet rs=stmt.executeQuery("select * from student");
while(rs.next()){
out.println("<tr>");
out.println("<td>"+rs.getString("id")+"</td>");
out.println("<td>"+rs.getString("name")+"</td>");
out.println("<td>"+rs.getString("age")+"</td>");
out.println("<td>"+rs.getString("part")+"</td>");
out.println("</tr>");
}
rs.close();
stmt.close();
con.close();
%>
</table>
</body>
</html>
出现的问题是:javax.servlet.ServletException: com.mysl.jdbc.Driver
可是我已经把mysql驱动的.jar文件放到WEB-INF\lib\了
如何解决请各位帮帮忙了.
