[解决办法]
The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: E:\Java\jdk1.6.0_10\bin;.;
这一句的意思是说你的java环境变量找不到，看看路径配置是否出现问题（环境变量配置完，在doc窗口运行下，看编译，运行能否通过）！这样会引起后面的‘source’资源问题错误。
严重: Exception starting filter struts2
java.lang.ClassNotFoundException: org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
这一句你到的类没错，在struts2中确实导入这个，就看代码写的有误没，有可能就是找不到jar包，还是前面问题引起的，
<!-- Struts2 配置-->
<filter>
<filter-name>struts2</filter-name>
<filter-class>
org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
[解决办法]
tomcat 清理一下
