问题描述
这是STRUTS的配置：<action name="addLine" class="action.MetroLineAction" method="addLine"><result name="success" type="redirect">getLines?cityArea=${cityArea}</result></action>ACTION中参数cityArea也有get、set：public String getCityArea() {return cityArea;}public void setCityArea(String cityArea) {this.cityArea = cityArea;}这是外部包的引用：报错信息如下：message description The server encountered an internal error () that prevented it from fulfilling this request.exception javax.servlet.ServletException: Filter execution

问题补充：业务大概是这样的，添加页面跳到添加的action里，添加成功后直接传一个参数转到另一个action,当配置文件读这个参数的时候报的错。
解决方案
引用root cause java.lang.NoClassDefFoundError 汗。。。你哪个class没找到没贴出来吧。。。。一般NoClassDefFoundError 后面会提示哪个类的吧个人觉得要不就是缺包 要不就是包多了
解决方案二：
你把你的struts2中对应过滤器的配置信息帖出来吧
解决方案三：
报过滤器执行出错和java.lang.NoClassDefFoundError错误，NoClassDefFoundError表示在类加载时候未找到定义--该类不存在。综合下，可能是你过滤器配置路径或者未导入对应过滤器的包。看看你的配置文件中过滤器的配置
解决方案四：
看错误提示估计是jar包的问题，找找看是否有这个包，或者有包冲突，删掉多余的就可以了！
解决方案五：
如果是前台传入后台的时候发的错误，那么就看看你的属性设置，你可以把这个city属性删了，再看看是否还报错，
解决方案六：
有说是classpath里没有设置 “.” 导致的…试一下
解决方案七：
是不是设置了ｄｅｖＭｏｄｅ =ｔｒｕｅ了. 改成ｆａｌｓｅ 试试看.
解决方案八：
你的包有点多。
解决方案九：
囧 那你把<result name="success" type="redirect">改成forward试试 不要用redirect
