WCS Interview Question

Q1 ) what is the difference between the controller command and task command.

        ANS : Generally controller command is the main command which we used to call from the JSP to process the request, But task command is used to perform some specific task like for inventory check, price check, these are handled through task commands, so task command are command which perform specific task for controller command.
