Re: how to write json/xml output using struts 2 and rest + convention plugin
I'm not familiar with this application but simply look at the
documentation for the struts2-json-plugin, you can specify a json
result and you can specify include and exclude parameters (so you just
return the part(s) of your Action you want). In this way you could
define a new map, put a key of "results" with a value of "New order
created successfully" and return it quite easily. If the struts2
document is insufficient there are plenty of examples also on
StackOverflow, so take a look there too (Including many annotation
based examples).

how to write json/xml output using struts 2 and rest + convention plugin
i've downloaded the demo apps for struts 2 v2.3.5 SNAPSHOT for today.
i am trying to understand and study the rest struts2-rest-showcase
webapp.
in the rest showcase, the OrdersController class has the following method.
public String editNew() {
model = new Order();
return "editNew";
}
the user is taken to orders-editNew.jsp. on this page, the form posts
to: action="%{#request.contextPath}/orders". the action to handle this
form is as follows.
public HttpHeaders create() {
ordersService.save(model);
addActionMessage("New order created successfully");
return new DefaultHttpHeaders("success").setLocationId(model.getId());
}
at this point, the user is taken to orders-index.jsp. however, i do
not want to take the user to this page. i instead want to write a
JSON/XML message back saying something (just like the action message)
to indicate success/failure. how do i do this?
i imagine my client application posting data to: /orders/new
and then receiving some JSON message:
{ "results" : "New order created successfully" }
any help is appreciated.

There's another bit, a complication perhaps, in that I'm trying to extend the ActionSupport, not replace it. My use case is that some folks before my time wrote their own i18n layer instead of using the framework's and I want to layer those text lookups in front of the framework's own. - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org

ActionSupport base on property injections so you cannot base on anything which is injectable - you cannot use getTextProvider during initialisation time (construction time). You can implement your own ActionSupport with constructor injected TextProvider that should solve your problem.

DI will use the default constructor, the others are used in other places (TextProviderFactory and ) - that's why it isn't an optimal solution. DI supports also constructor injections, in the same way as property injection, just add @Inject to constructor.

implementaiton advise on custom TextProvider
So, I want to have the framework use my own custom TextProvider. Since the framework uses DI to inject such things, I've been able to have my own custom TextProvider injected into the system. Now, I'm encountering some other issues related to how to correctly initialize my custom provider. ActionSupport#getTextProviderSupport() uses the TextProviderFactory to obtain it's instance of a support object. Since it uses the di to inject this into the factory, my custom version is correctly injected. However, I need to initialize my custom support object with a resource that it needs to conduct its business. Note, the default TextPRoviderSupport also needs a couple of resources, and those are initialized in the factory's createInstance( Class class, LocaleProvider provider ). So, while I've injected my own class, there doesn't seem to be a clean way to make sure that it's initialized properly. Should I extend the factory to handle my class and init it too? Doesn't seem very DI-ish . . . hardcoding type specific init logic, I mean. Or should I create an interceptor that will inject the correct resources into my text support object? - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
RE: overriding framework components
> > Here you have the full list of extension points > > http://struts.apache.org/2.x/docs/plugins.html#Plugins-ExtensionPoints > Excellent. Thank you. And, since I think I saw your name on some comments in the TextProvider, I wonder what constructors get invoked when the TextProvider is injected in the TextProviderFactory on ActionSupport. The default TextProviderSupport has references to locale provider and a class, which can be set via a constructor. But I suspect the DI must only use the parameterless constructor. Is this true? In what cases do those other constructors get invoked?

I thought a bit more about that and this can be achieved by a PrincipalProvider (as TextProvider) which can be injected onto interceptors or any other place. It will produce PrincipialProxy base on HttpServletRequest, eg. PrincipialProvider#getPrincipialProxy(HttpServletRequest) Regards -- Łukasz mobile +48 606 323 122 http://www.lenart.org.pl/ Warszawa JUG conference - Confitura http://confitura.pl/ - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
