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：
java.sql.SQLException: Table 'nihai2007.sq_online ' doesn 't exist

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&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull
user =root
password =root
maxconn =20
