严重: Error filterStart

严重: The web application [/lbs] registered the JDBC driver [com.mysql.jdbc.Driv
er] but failed to unregister it when the web application was stopped. To prevent
 a memory leak, the JDBC Driver has been forcibly unregistered.

严重: The web application [/lbs] appears to have started a thread named [MySQL S
tatement Cancellation Timer] but has failed to stop it. This is very likely to c
reate a memory leak.

严重: The web application [/lbs] created a ThreadLocal with key of type [com.ope
nsymphony.xwork2.inject.ContainerImpl$10] (value [com.opensymphony.xwork2.inject
.ContainerImpl$10@3c33d3]) and a value of type [java.lang.Object[]] (value [[Lja
va.lang.Object;@6e7127]) but failed to remove it when the web application was st
opped. Threads are going to be renewed over time to try and avoid a probable mem
ory leak.

项目可以在eclipse下完好运行，结果部署到服务器上了就报如上的错误。
对于菜鸟的我当然就跟着网上找资料。发现遇到此情况的道友也很多。
关机重启，更改tomcat service.xml ，更换各种高低版本的tomcat，都没有解决 。
最后发现了是包的问题。
我的是用Meaven进行管理的。就是如下的文件

<dependency>
   				 <groupId>com.opensymphony</groupId>
    			 <artifactId>xwork-core</artifactId>
                <version>2.1.6</version>
          </dependency>

此文件对应生成的有三个jar．１，spring-test-2.2.6 ２，xwork-core-2.1.6 ３，JUNIT-3.8.1
删除这三个Jar,总算就可以了。
记下以防下次再有类似问题发生。
