2011-5-18 9:05:10 org.apache.catalina.loader.WebappClassLoader clearReferencesJdbc
严重: A web application registered the JBDC driver [com.microsoft.sqlserver.jdbc.SQLServerDriver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.
2011-5-18 9:05:10 org.apache.catalina.loader.WebappClassLoader clearReferencesStopTimerThread
严重: A web application appears to have started a TimerThread named [Timer-1] 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.

查阅是xml-apis.jar  ，xerces-2.6.2.jar有问题，之后将这两个包放到到tomacat的lib下面就ok了。

备注：我将项目1的xerces-2.6.2.jar删除问题解决了
