首先非常感觉贵公司做出这样出色的开源产品！小弟在安装过程中出现了以下问题，麻烦管理员帮忙解决一下！
我在安装完成的时候出现以下exception.
2010-5-7 9:45:12 org.apache.catalina.startup.HostConfig checkResources
信息: Reloading context [/j2ee]
2010-5-7 9:45:12 org.apache.catalina.loader.WebappClassLoader clearReferencesJdbc
严重: A web application registered the JBDC driver [com.mysql.jdbc.Driver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.
2010-5-7 9:45:12 org.apache.catalina.loader.WebappClassLoader clearReferencesStopTimerThread
严重: A web application appears to have started a TimerThread named [MySQL Statement Cancellation Timer] via the java.util.Timer API but has failed to stop it. To prevent a memory leak, the timer (and hence the associated thread) has been forcibly cancelled.
