How to use spring mvc for adding,editing , deleting
a machine category obejct
say .... MCategory object
it has only id and name as attri.

Hibernate is used for persisting.


In one form i want to have the functionality of add, edit and delete option .

In one part of the Form will have one entry screen in which one input
field of name of the machine category will be there .

In another part of the form , there will be list of already
entered m/c category . in each row of m./c category , there will a edit and a delete button by which edit and deleting
can take place.

this form will be bounded to command object called
mcategory

1. when adding , it will take to one handler or controller
. this controller will just call the service add method

2. when editing ,there will be hidden id , this will take to
another controller and this controller will make
the command object and return back to the form for
submit after editing

3. when deleting , there will be also hidden id , this will take
to another controller and this controller will
delete the machine category of this id


How to implement the above using Spring web MVC

TIA
