If I get it right, the EmployeeAction is used in different requests/contexts
and on success redirects to a variety of jsps. Of these only two jsps need
this list and you dont want to fetch them until you need it?
1) The idea of getter sounds good. Struts calls getter only when you have
the s:select tag. Dont see a problem with it myself.
2) I would subclass the EmployeeAction for the two jsps and put the prepare
call while skipping the rest.
