Where do I write Bussiness Logic that using struts framework? is that we write in action class? or any?

Yes, business logic is written in action class.There is one action class for each module , say, for eg if u have login module, then u can have LoginActionClass.java , where u can implement business logic.

Hi,

you have to write the business logic in EJBs.
and call the EJBs from Action class.
Action will make decision like which JSP page has to be called next

Never implement business logic in action class,its not recommended.its visible to client and its tight coupled.
Always delegate the biz logic using form beans or DTO or EJB.

Action is only controller, it handles request from actionservlet and forwarding to view pages.

Never think of putting business logic in the action classes. Its not the way to work using struts. Action classes r only to act as a controller which delegates the control to some DAO, EJB objects. So always put ur business logic in DAO or EJbs...while using struts framework

No business login should be written in a Model class which can be called from Action class.


we can write BL in Action class even but the if u want the same BL to be applied for an GUI application we need to write the same BL code again.

But if we write the BL code in Model class this can used by Action class of Struts Frame work as well as GuI application also

it is better to write BL in either POJo(PlainOldJavaClasesses)/EJB
