ModelAndView :

View -> jsp to display , path mention chestham
Model -> AppBean which uses as model in the jsp.

Earlier spring version return type string vundedhi (we can use that still) .. So model set chesi.. return lo "jsp path " mention chese valla.. But now.. we can return ModelAndView ..



BindingResult - is one of the input to the Spring validator , and validation appudu emaima errors vasthey it will be in binding result. This contains the messageCode to display , variableName for the filed to which validation fails. like that

Nenu just overlook cheppa..

between what information register holds , when this method is getting called.

in the mentioned..

if the role is admin they are create a new register object and going ahead further.

if role is other the than admin , they are redirecting to register jsp.

if role is null , they are passing the same register object .. until the functionality is not clear , its difficult to say.. as register object is defined based on ur project need.


Project looks like.. as its being developed by fresher.. is this a curicullam project
