struts2 配置，总体是找不到org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecute
struts版本是 2.1.6

导入JAR包时点的是 Add External JARs
导入了

struts2-core
ognl
freemarker
xwork
commons-logging
commons-fileupload
这6个包

web.xml配置如下


<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
  <display-name>fdsfds</display-name>
  <description>fdsfds</description>
  <welcome-file-list>
  <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
   
   
<filter>
  <filter-name>struts2</filter-name>
  <filter-class>org.apache.struts2.dispatcher.Filterdispatcher</filter-class>
  </filter>

  <filter-mapping>
  <filter-name>struts2</filter-name>
  <url-pattern>/*</url-pattern>
  </filter-mapping>
</web-app>


总体是找不到org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter这个类

提示堆栈信息如下:

大小写检查了无数遍了，还是没查出问题来..
什么原因呀？
是不是和tomcat里一些jar包重复的原因??



------解决方案--------------------
<filter>
<filter-name>struts2Filter</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
这样配置是是
------解决方案--------------------
个人认为可能是struts.xml配置的问题，把struts.xml贴出来看看

看错了，不好意思
