Add function in Controller

[Sapan]

I am new to ROO project. I have looked a lot but unable to find "How can I manually add function in one of my controller"? Suppose my controller looks like:

  
package ch.epfl.psytest.web;

import org.springframework.roo.addon.web.mvc.controller.RooWebScaffold;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import ch.epfl.psytest.domain.Slide;

@RooWebScaffold(path = "slides", formBackingObject = Slide.class)
@RequestMapping("/slides")
@Controller
public class SlideController {

}

To add function in SlideController: Can I manually add function like this? (please also tell if I have to something in other files also)

 
public void addSilde(Slide s) {   
  .
  .    
  . }

or is there any way to add function using ROO command shell? and How can I access this function?

Thanks in advance!
