我用的struts2 2.2.3
把
commons-fileupload-1.2.2
commons-io-2.0.1
commons-lang-2.5
commons-logging-1.1.1
freemarker-2.3.16
javassist-3.11.0.GA
ognl-3.0.1
struts2-core-2.2.3
xwork-core-2.2.3
这几个包都导入了
但启动tomcat的时候会报 严重: Exception starting filter struts2

照提示是说找不到那个类，但我绝对导进去了，就是这个包struts2-core-2.2.3
我把我的XML配置文件也放出来一下
web.xml
- Java code
<?xml version="1.0" encoding="UTF-8"?><web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"><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>
struts.xml

------解决方案--------------------
Struts2.2.3好像不是这么配的。
你把你下载到的Struts的那个压缩包里面的例子的web.xml打开来看一下，他的例子是怎么配置的，你按照那个改过去就行了。我记得不是这个FilterDispatcher
