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]

[解决办法]
你的js和jsp文件是在一起还是分开的
[解决办法]
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
[解决办法]
你是交给spring管理的？
[解决办法]
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
[解决办法]
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>
[解决办法]
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
[解决办法]
