Answer 1

你的js和jsp文件是在一起还是分开的

Answer 2

严重: Servlet.service() for servlet jsp threw exception
The Struts dispatcher cannot be found. This is usually caused by using Struts tags without the associated filter. Struts tags are only usable when the request has passed through its servlet filter, which initializes the Struts dispatcher needed for this tag. - [unknown location]
 
这个不是原因么

Answer 3

js和jsp一起的啊，在一个页面里。

Answer 4

交给spring管理需要在web.xml中加上
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param> <listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
然后在spring中配置action
如果不是<action name="empHistoryList" class="empUpdateAction" method ="getEmpHistoryBy">必须带上包名+类名

Answer 5

为什么楼主的action要写成这样
<%=request.getContextPath()%>/report/workerStatistics1.action?falg=1"楼主的action难道没有在struts的xml文件里面配置吗？
例如
<action name="action的名称" class="action的位置" method ="方法名">
<result name="error"></result>
<result name="success"></result>
</action>

Answer 6

web.xml中struts的拦截改为.action,还有确保你的<action name="empHistoryList" class="empUpdateAction" method ="getEmpHistoryBy"> class引入的类是否正确

Answer 7

是用的spring管理的，xml里也配置了；？？？然后在spring中配置action
如果不是<action name="empHistoryList" class="empUpdateAction" method ="getEmpHistoryBy">必须带上包名+类名？？？
为什么在spring里配置action啊，我在struts里配置了啊，用的SSH框架

看下你spring的配置，看是否配置了name='empUpdateAction'的bean
