Thread: Action Mapping error in Struts2

Hi All,

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

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

What does your struts.xml look like?
