今天找的源码中 有spring的知识 但是我还没有接触到
所以一直报

严重: Error filterStart
错误 好像是spring影响了struts吧？？（个人猜想）

这是我的 web.xml文件 大家帮帮忙吧 趴求答案 谢谢
------解决思路----------------------
java.lang.ClassNotFoundException: ognl.PropertyAccessor
少了jar包 ognl-3.0.6.jar
------解决思路----------------------
1、看看有没有少ognl这个jar包（添加Struts2这个版本对应的ognl)
2、如果有ognl包，看看是不是有包冲突
------解决思路----------------------
少包，或者包冲突。对比找找看看。
------解决思路----------------------
如果少包的情况下肯定是运行不成功的！
------解决思路----------------------
目测ognl包缺少，如果楼主不是正在做项目的话可以使用SpringMVC，以后用SPRINGMVC的越来越多；只要做企业及开发的。因为和SPRING能很好进行集成且少了很多重复的JAR包。
------解决思路----------------------
ognl.PropertyAccessor 这个类没找到，应该是你没有加ognl的jar包吧
------解决思路----------------------
很明显 没有ognl jar包
