No, if your application is a simple CRUD I'd recommend to do it in classic way, with REST you're building more an API than CRUD - and designing API is hard :-) > 2.

That's all, maybe some book but I cannot recall which one. Can you address what are you missing in REST plugin documentation > 3.

With REST you must return a bit more than just a result name to use - ie. status code, cache, etc, that's why HttpHeader is used instead - just to be clear, even from ordinary Struts action you can return result directly, eg. instead return "success" do return new ServletRedirect(...) > 4. Should actions always implement ModelDriven? Nop, as far I remember no > 5. Why not extending ActionSupport?

Yes you can, but as REST is just limited to returning simple data (JSON) all the boilerplate of ActionSupport isn't needed. It's also recommended way, to implement your own version (or even few) of ActionSupport - basically it's just a set of simple interfaces, check implementation. > 6. Is convention plugin required? How to do REST without it? No, but it's quite simpler. > 7. Example application 'struts2-rest-showcase' is not working: 'HTTP 404 - > There is no Action mapped for namespace / and action name orders.' cd apps/rest-showcase mvn jetty:run open http://localhost:8080 works! > 8.

I will try to fix that, anyway we are in process of moving all the examples from Java source codes to Wiki (to solve problems like that) Regards -- Łukasz + 48 606 323 122 http://www.lenart.org.pl/ --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
