启动项目时，一直报错：

2012-8-1 17:59:13 org.apache.catalina.loader.WebappClassLoader modified
信息: Additional JARs have been added : 'jaxb-impl-2.0.1.jar'
2012-8-1 17:59:13 org.apache.catalina.core.StandardContext reload
信息: Reloading this Context has started
2012-8-1 17:59:13 org.apache.catalina.loader.WebappClassLoader clearReferencesJdbc
严重: A web application registered the JBDC driver [org.logicalcobwebs.proxool.ProxoolDriver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.
2012-8-1 17:59:13 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.
2012-8-1 17:59:13 org.apache.catalina.loader.WebappClassLoader clearReferencesThreads
严重: A web application appears to have started a thread named [HouseKeeper] but has failed to stop it. This is very likely to create a memory leak.
2012-8-1 17:59:13 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.

看提示信息还以为是数据库的问题，就去搜索org.apache.catalina.loader.WebappClassLoader clearReferencesJdbc，找很久还是没有解决，后来搜索“org.apache.catalina.loader.WebappClassLoader modified”找到一篇文章http://bj-sunny.iteye.com/blog/676670，说是“Additional JARs have been added : 'jaxb-impl-2.0.1.jar'”提示的jar包有问题，我用反编译软件查看该包，没有任何文件，然后重新放入一个jar，问题解决了
