I'm having problems with chaining. I have tried several ways but none works. For instance:
1. http://localhost/mycontext/secure/protected => Login.jsp (${#request.url} is readable in jsp). 2. Login.jsp => submit (correct user/pwd) => ERROR: Infinite recursion detected: [//authenticate!authenticate, //, //] (url not available as request attribute) When submitting, request attribute 'url' is not present in the action, I guess because result type of "input" is "dispatcher", not "chain", but using type "chain" with a JSP causes St2 to complain, and won't find any action. Pseudo-code: INTERCEPTOR if (userInSession == null) { request.setAttribute("url", request.getServletPath()); return "AUTHENTICATE"; } return invocation.invoke(); STRUTS.XML - package base, namespace "" - defines interceptor SECURE and default interceptor stack (SECURE, DEFAULTSTACK). - defines global result: <result name="AUTHENTICATE" type="chain"> <param name="actionName">authenticate</param> <param name="namespace">/</param> </result> - package root extends base, namespace "/" <action name="authenticate" class...> <result type="chain"> <param name="actionName">${#request.url}</param> </result> <result name="input">/Login.jsp</result> </action> - package secure extends base, namespace "/secure" <action name="protected" class=...> <result>/secure/Protected.jsp</result> </action> ACTION AUTHENTICATE if (userInSession != null ) { request.getSession().setAttribute("USER_IN_SESSION", userInSession); //expecting original url is a request attribute return SUCCESS; } else { return INPUT; } At the moment I've not been able to implement the requirement.
