json.jsp 第6行执行出错栓查一下.

貌似是 "<jsp:useBean id="example" scope="session"
class="net.vicp.jiasoft.Example" />"
这一句.

jdbc:mysql://localhost:3306/test?autoReconnect=true, UserName=root@localhost, MySQL-AB JDBC Driver
你找一下其它的原因。

测试了你的代码，配置是没有问题的。测试代码如下（只是数据库换成了test,密码换成我的mysql）：

tomcat配置如下：


1<Resource name="jdbc/test" auth="Container" type="javax.sql.DataSource" 

2maxActive="100" maxIdle="30" maxWait="10000" 

3username="root" password="mysql" driverClassName="com.mysql.jdbc.Driver" 

4url="jdbc:mysql://localhost:3306/test?autoReconnect=true"/>



jsp代码如下：


 1<%@ page contentType="text/html;charset=gb2312"

 2 import="java.sql.*,javax.sql.*,javax.naming.*"%>

 3

 4<html>

 5 <head>

 6  <title>留言板</title>

 7 </head>

 8 <body>

 9  <a href="#">我要留言</a>

10  <%

11   Context ctx = new InitialContext();

12   DataSource ds = (DataSource) ctx.lookup("java:comp/env/jdbc/test");

13   Connection conn = ds.getConnection();

14   out.println(conn);

15  %>

16 </body>

17</html>

18

输出为：


1org.apache.tomcat.dbcp.dbcp.PoolableConnection@160c4b0 



我用的驱动为：mysql-connector-java-5.0.8 下载地址：http://dev.mysql.com/downloads/connector/j/5.0.html

Tomcat为：5.5.29版



建议你换个驱动试一下。

贴一下你的代码吧，这样我才好看。
