Default result is not rendering using result for my package alone. Flow goes to my n0result method then It throws Exception.
Please correct
What ever the string value your are returning from the action class method. You must declare a result name with the returned string value.
example in your code:
Change
to
OR
You can add one more result in the action. like below
/noresultend.jsp
/noresultend.jsp
/noresultdefaultdispatcher.jsp
I hope It ll work.
