Hello, We are starting to use Struts and are wondering how Struts users handle scenarios such as this one:
1. /ShowForm action gets called, mapped to ShowFormAction. ShowFormAction pulls a list of countries from the DB (for ex.), stick that list in the HTTP request, and 'forwards' to 'ok', which is a JSP with a form that consists of blank form fields and a pull-down with countries that it gets from the HTTP req. 2. A user fills the form, but forgets a required field before he submits the form by POSTing to /SubmitForm action. 3. /SubmitForm is mapped to SubmitFormAction which detects a missing required field. Is puts error messages in an instance of ActionErrors. It now needs to forward to something other than 'ok'. What we want to happen at this point is: A. Get the user back the input form B. Display the error message C. Make sure that all possible fields are pre-populated with data that the user already entered D. The pull-down in the form has that same list of countries E. The user is not prompted with 'Do you want to re-POST' dialog How can this be done? In our Struts config we have: <!-- gets a list of countries from DB, puts them in Request, forwards to 'ok' --> <action path= "/ShowForm" type= "net.wgen.ampng.action.ShowFormAction" scope= "request"> <forward name= "ok" path="/WEB-INF/v/form-ok.jsp"/> <forward name= "failure" path="/WEB-INF/v/form-not.jsp"/> </action> <!-- gets form data and processes it --> <action path= "/SubmitForm" type= "net.wgen.ampng.action.SubmitFormAction" scope= "request" validate= "true" name= "myForm" input= "/WEB-INF/v/form.jsp"> <forward name= "ok" path="/WEB-INF/v/ok.jsp"/> <forward name= "failure" path="/WEB-INF/v/form.jsp"/> </action> What is the best way to handle this and achieve A, B, C, D, and E that I mentioned above? If SubmitFormAction encounters an error (e.g. a missing required field), what should it forward to? The original JSP in 'input' attribute? The JSP mapped to 'failure' (the same JSP with the original form)? Should it forward/chain to another Action that redirects back to the original form? (but that would lose the form data + error messages in the Request, wouldn't it?) Something else? Does the JSP with the form need to contain the logic for pulling errors + form data from the request, if it exists? This seems like a situation that would be very common and I feel that Struts has some elegant way for handling this.
