Answer 1

到你的TOMCAT目录的 work 里边 找找 org.apache.struts.action.ActionServlet
看看找到了么

Answer 2

java.lang.ClassNotFoundException: org.apache.struts.action.ActionServlet
错误提示是类找不到，看看applicationContext.xml,web.xml中是否配置正确。 或者是你看看你是否有这个jar包啊，找找！

Answer 3

java.lang.ClassNotFoundException: org.apache.struts.action.ActionServlet
错误提示是类找不到，看看applicationContext.xml,web.xml中是否配置正确。 或者是你看看你是否有这个jar包啊，找找！没用Spring只用的是Struts1.x。web。xml中：
<servlet>
    <servlet-name>action</servlet-name>

    <init-param>

Answer 4

java.lang.ClassNotFoundException: org.apache.struts.action.ActionServlet
是STRUTS最核心的类，是不是struts.jar没有在\WEB-INF\lib下啊？

Answer 5

to 阿甘：有在lib下面导入了八个关于struts的包，其中就包含struts.jar

Answer 6

导入的包：
antlr.jar
commons-beanutils.jar
commons-digester.jar
commons-logging.jar
commons-fileupload.jar
commons-validator.jar
jakarta-oro.jar
struts.jarweb.xml的配置：
<servlet>
  <servlet-name>action</servlet-name>
  <servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
  <init-param>
  <param-name>config</param-name>
  <param-value>/WEB-INF/struts-config.xml</param-value>
  </init-param>
  <init-param>
  <param-name>debug</param-name>
  <param-value>2</param-value>
  </init-param>
  <init-param>
  <param-name>detail</param-name>
  <param-value>2</param-value>
  </init-param>
  <load-on-startup>2</load-on-startup>
  </servlet>

  <welcome-file>login.jsp</welcome-file>
  </welcome-file-list >

Answer 7

你在struts.jar里看一下有没有这个类org.apache.struts.action.ActionServlet

Answer 8

可能是web.xml里面出错了，也有可能缺少struts.jar包。试试重新导一下那几个包，看看有没有问题，如果还是一样，就是web.xml里面有问题了。

Answer 9

struts.*.*.jar这个东东没有找到

Answer 10

java.lang.ClassNotFoundException: org.apache.struts.action.ActionServlet
jar package is missing ?
