Can I use a parameter instead of a hard coded value in the mappings of a struts-config.xml? If so, how?What I mean is: I have a config file that looks like so: <action path="/myAction" type="com.softrek.conference.MyAction" name=" myForm" scope="request" validate="false" > <forward name="winMoney" redirect="true" path="winner.jsp" /> <forward name="loser" path="thankYou.jsp" /> .... </action> This requires an Action that has exactly 'winMoney' and 'loser' as the strings in the mapping.findForward(). Can I use some sort of ForwardNames.WIN_MONEY instead? Or any other parameter that will keep the strings identical. Ideally with only one place to modify the string if it changes. Is this possible? How?
I don't believe there's any way to refer to a static Java constant from within struts-config.xml, unfortunately. However, there are a couple of projects which aim to replace XML configuration with annotations for Struts 1, which might at least allow you to collect everything into one place (the action class).
Another popular approach is to use a small set of 'well known' result names ('SUCCESS', 'ERROR', 'FAILURE', etc) which you can then reference as constants in your action classes. You still have to make sure that your action returns and your config match up, but with a limited set of possible values it'll be easier to spot if you have a mis-config.
