Struts2 Action mapping error

I am new to Struts2, I have been facing an action mapping issue in my Application. The error message says

Struts has detected an unhandled exception:

Messages: There is no Action mapped for namespace / and action name "yourActionName". Stacktraces

There is no Action mapped for namespace / and action name "yourActionName". - [unknown location] com.opensymphony.xwork2.DefaultActionProxy.prepare(DefaultActionProxy.java:178) org.apache.struts2.impl.StrutsActionProxy.prepare(StrutsActionProxy.java:61) ...

The issue is intermittent and it occurs like very rarely. I have verified the action mapping in struts config file and also in JSP action seems to be correctly mapped. As far as I have understood, sometimes the action tries to map to wrong namespace. I have defined the namespaces in all the concerned JSP. Nothing seems to be wrong with the controller layer.

Please help me with this issue

The same problem came into my application you should change your filter name

 <filter-class>
 org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
 </filter-class>

and after that you should clean your project then run it again if you get error then change the filter by this

 <filter-class>
     org.apache.struts2.dispatcher.FilterDispatcher
  </filter-class>

Do same process that is mentioned above it will work correctly because dispatcher.FilterDispatcher is deprecated after struts2.3.
