------ Solution ------------------------------------ --------

com.serlvet.Login this class has it ? ? ? configuration does not know there is no problem , you can see whether you can access other action , make a comparison and then look
------ Solution ------------ --------------------------------
userLogin into this class U serLogin
------ For reference only ------------------- --------------------
No action instance for path / login could be created
The server encountered an internal error (No action instance for path / login could be created) that prevented it from fulfilling this request.
