Question
What is the difference between controller and task command.?
Answers
Controller Command is the command that gets called upon a request, just like We have actions in struts and controller in Spring. Task is a step in this bigger process. Task command are the commands that perform specific task for a controller command, like service classes in other frameworks. In order to complete the request, a controller command may invoke multiple task commands.
Other difference are:

There is a url mapping for controller command whereas Task command don't have URL mapped to them.
Controller command gets invoked before the task command.   Your Comment
