Re: Design question: Confirm action after validation ?
I have an Action base class which all my other Action classes inherit. In the execute() of this base class I check whether the user clicked cancel, before I call the child class execute(). I presume it would be easy enough to store the originating URL in the session, and if cancel is clicked, roll your own Action Forward back to this URL. Since it is all in the base class, it could work for every action as long as you are careful to watch the parameters or ids.

Re: Design question: Confirm action after validation ?
Hello Adam I have one doubt. You have base action class for all your subaction classes. What is the responsibility of this base action class. Do your base action class checks which button is clicked? If there are say 10 buttons in one form (say, GO, ADD, SAVE, NEXT, etc) are there 10 if statements in your class. Or it is sub action class resposibility to check this.? are there 10 or (any no) of if statements in subaction classes.? How to eliminate those if statements? any idea?

Re: Design question: Confirm action after validation ?
my base action class sorts out all the general objects and variables that the child actions need - this is the child action's execute() signature: public String executeList(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response, BlackSailUser user, Locale locale, MessageResources messages, ActionErrors errors, Connection conn) throws Exception I guess the list of responsibilites for the base action superclass is: (1) establish the action to carry out (your GO, ADD, SAVE etc) which is a token that is set by any of a request parameter, request attribute, action mapping parameter, or cancel button. (2) get a jdbc connection object from pool (3) get message resources from request (4) get locale from request (5) get user object from session (6) get errors from request (7) error handling (I don't have any in my subclasses) (8) get any lists for drop-down boxes (a seperate call to subclass) Had to check that out by looking at the code. It served me fine since my first struts app. Shashank Dixit wrote: Hello Adam I have one doubt. You have base action class for all your subaction classes.

Re: Design question: Confirm action after validation ?
Hi again Are you using EJBs?? If you are using EJB, where is the connection pool? At webserver side or app server side. Or where datasource is defined. at web server or app server?

Re: Design question: Confirm action after validation ?
I plan on using EJB but haven't got that far yet. At the moment I am using a bunch of 'factory' classes as my model, and would like to isolate this layer from the request, response objects etc in the actions. So the fact that I get the connection in the base action is a legacy thing - I thought about changing it and probably will soon, to a strategy where the actions don't see the connection. I changed the database configuration so that the pool is a JNDI resource, but I haven't got around to this second bit yet because the interface between the actions and the factories requires more thought as to how I marshall the data across.
