HTTP Status 404 - There is no Action mapped for namespace [/] and action name [courseTypeAction_findAll] associated with context path [/crm].

<struts>	
	<!-- 崗位私有配置 -->
	<package name="post" namespace="/" extends="common">	
		<action name="postAction_*" class="wang.crm.post.web.action.PostAction" method="{1}">
			
		</action>	
	</package>	
</struts>
