Re: Doubt on Struts 2 Architechture
Actually, no, it's not executing them again, it's finishing the original execution. The interceptor does whatever it's supposed to do before the execution of the action, it then turns over control to Struts which decides whether there is another interceptor in the chain, or whether it's time to execute the action. When the action is done, the call returns control back to each interceptor in (as you said) reverse order where it can finish it's work. It's the simplest and most effective way of assuring the interceptors can do both pre-processing and post-processing.

excludeMethods parameter question
Hello list! I'm making a research about Struts2 and there are several things that I don't understand (haha), I have studied really hard and I think I'm in the righ way now, but there's a thing that i don't understand about this examples i found about interceptors, i'm talking about the parameter excludeMethods. I have seen that most of the times it has input,back,cancel but I don't really know what does it mean. Can u help me guys please? -- Manolo Pájaro Santander Ingeniero de Sistemas VIII Semestre (Actual) Promoviendo el Software Libre CUSOL-UAC Linux Registered User # 522026
Re: excludeMethods parameter question
There are some interceptors, like validator one, which are not triggered in case of the name of the invoked method matches one of the list element (there is no reason to validate an input action, you don't yet obtain the user input, so you have anything to validate). Hope this help. Maurizio Cucchiara Il giorno 25/lug/2011 23.11, Mano Pájaro mano0...@gmail.com ha scritto: Hello list!

Thanks Maurizio, let me see if i got it straight.

Re: excludeMethods parameter question
Not exactly. It would not execute for actions whose method name is input, back or cancel. It's on the action side, not the result side.

Re: excludeMethods parameter question
I see mm so, it only acts on the action which method attribute is diferent from in the list, that's it? :D 2011/7/25 Chris Pratt thechrispr...@gmail.com Not exactly.

Re: excludeMethods parameter question
Exactly, so the default (execute) would run the validation, but not the ones that are listed.
