Actually mentioned action type in UI component is being same as in action path in struts config file,its a way we have to put names both are same.we are requested to one and matched with the action path-name in action-mappings should be same in this situation.Just change those if its working then ok else let me know the reason.

Thanks,
Venkat.

Hi Venkat,

As You suggested I changed the action path name different from action type in UI.

I got the below error.

Hi Sandeep,
