jsp+连接池+mysql出现很奇怪的错误，从来都没有见过！
我在连接数据时，也能连上，并且能把数据读出来。
但是eclipse的控制台里一直都在报错。
刚开始报：Query:com.mysql.jdbc.PreparedStatement@1b71c12:   select   msgRootId   from   plugin_auction   where   orderId=-1   and   endDate < '1187076329609 '   and   sellType=0---Table   'nihai2007.plugin_auction '   doesn 't   existQuery:com.mysql.jdbc.PreparedStatement@1370ab:   select   msgRootId   from   plugin_auction   where   orderId=-1   and   endDate < '1187076389796 '   and   sellType=0---Table   'nihai2007.plugin_auction '   doesn 't   existQuery:com.mysql.jdbc.PreparedStatement@12ad974:   select   msgRootId   from   plugin_auction   where   orderId=-1   and   endDate < '1187076450000 '   and   sellType=0---Table   'nihai2007.plugin_auction '   doesn 't   existQuery:com.mysql.jdbc.PreparedStatement@1b9ef8c:   select   id   from   sq_message   where   color <> ' '   and   colorExpire < '1187076500250 '---Table   'nihai2007.sq_message '   doesn 't   existQuery:com.mysql.jdbc.PreparedStatement@766186:   select   id   from   sq_message   where   isBold=1   and   boldExpire < '1187076500250 '---Table   'nihai2007.sq_message '   doesn 't   existexecutePreUpdate:com.mysql.jdbc.PreparedStatement@1752bea:   delete   from   sq_online   where   staytime < '1187075602250 '---Table   'nihai2007.sq_online '   doesn 't   exist


就算我不对程序做任何操作，过上一会它会报下面的错误：

我就奇怪了，怎么也找不到问题在哪？
我用的是一个自己写的连接池，连接池的配置如下：
driver   =com.mysql.jdbc.Driver
url   =jdbc:mysql://localhost:3306/nihai2007?useUnicode=true&amp;characterEncoding=UTF-8&amp;zeroDateTimeBehavior=convertToNull
user   =root
password   =root
