Check out the javadoc: http://www.springframework.org/docs/api/org/springframework/web/servlet/mvc/multiaction/MultiActionController.html

It describes the legal method signatures:


ModelAndView getUsersAllUnsentExpenses(HttpServletRequest request, HttpServletResponse response);

or


long getUsersAllUnsentExpenses(HttpServletRequest request);

thanks yatesco
as u said i change the method signature


but problem is not solved yet now i got warning such as

01-May-2006 16:24:43 org.springframework.web.servlet.mvc.multiaction.Mu ltiActionController handleRequestIntern
al
WARNING: No handling method can be found for request [org.apache.coyote.tomcat5.CoyoteRequestFacade@85e5 7]




public ModelAndView getUsersAllUnsentExpenses(HttpServletRequest request,HttpServletResponse response) {

}

why do we are adding second param as response ?

is it to give response back ?

[Colin Yates]

Not sure why you get that error to be honest. I don't really have much experience with the MAC.

Is your method actually being executed?

[ganesh pol]

can u tell me what is the thumb rule to use controllers

which one to use when

i.e when to use SimpleFormController and MultiActionController

and how to solve above problem

[Colin Yates]

I always prefer using seperate controllers. I understand why people use MultiActionController, but I do not use it much. Having seperate controllers isn't really that much more work/configuration than the MAC, but seperate controllers gives you a lot more flexibility.

If you have lots of related, trivial operations that are all related, then MAC might be OK. If you have any non-trivial operation than seperate controllers is the way to go.

Just my opinion. Others will disagree. And to be honest, I haven't really disproved MAC through experience, more a gut feeling :)
