这是错误 说我的 jdbc.driver有问题
我用的是mysql-connector-java-3.1.8，
把压缩包解压．提取当中的一个文件：mysql-connector-java-3.1.8-bin．jar
然后配置classpath路径，并把这个文件拷到tomcat目录下的\common\lib和\shared\lib
这样应该没有问题的！
mytest.jsp 代码如下：
<%@ page contentType="text/html; charset=UTF8" %>
<%@ page language="java" %>
<%System.out.println("111111111111111111");
//@ page import="org.gjt.mm.mysql.Driver" %>
<%@ page import="com.mysql.jdbc.Driver" %>
<%@ page import="java.sql.*" %>
<%
System.out.println("2222222222222222222");
//驱动程序名
String driverName="org.";
//数据库用户名
String userName="root";
//密码
String userPasswd="810833";
//数据库名
String dbName="test";
//表名
String tableName="name";
//联结字符串
String url="jdbc:mysql://localhost/"+dbName+"?user="+userName+"&password="+userPasswd;
Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection connection=DriverManager.getConnection(url);
Statement statement = connection.createStatement();
String sql="SELECT * FROM "+tableName;
ResultSet rs = statement.executeQuery(sql);
//获得数据结果集合
ResultSetMetaData rmeta = rs.getMetaData();
//确定数据集的列数，亦字段数
int numColumns=rmeta.getColumnCount();
// 输出每一个数据值
out.print("name");
out.print("|");
out.print("age");
out.print("<br>");
while(rs.next()) {
out.print(rs.getString(1)+" ");
out.print("|");
out.print(rs.getString(2));
out.print("<br>");
}
out.print("<br>");
out.print("数据库操作成功，恭喜你");
rs.close();
statement.close();
connection.close();
%>
请问哪位大侠能指点一二 谢谢！
