	Override an IoC service by P.Stavrinides :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message Hi, I have recently introduced a multiple IoC module structure into my web applications, so I have a core web module and then application specific modules separately, and now I am getting the following error: ERROR - Service interface com.albourne.web.interfaces.ISiteError is matched by 2 services: CoreError, SiteError. I have introduced these changes mostly for testing purposes... its not a big problem as I can simply remove the offending service from the shared core and provide an implementation of it in each application specific module, but it got me wandering about this issue on a larger scale, is it possible to override a service? if not would such a feature be useful? How do others deal with this, using service decoration potentially?

Yes, you can override services: http://tapestry.apache.org/tapestry5.1/tapestry-ioc/cookbook/override.html. -- Thiago --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@...

Or did I get lost somewhere? I am not sure to be perfectly honest, looking through that link I guess there may have been a case... in my situation Thiagos solution is perfect because I use a generic error handling service that is configured in the shared core module and is reused without change by many applications, but in one particular application I have to extend this service to override some of the handling... so far as I know I could do this either by: - decorating the service - not bind it in the shared core module, and then binding it each applications AppModule (my solution before) - Or implement the override (Thiagos suggestion), which I have now done But perhaps I could have done it that way as well? regards, Peter ----- Original Message ----- From: "nille hammer" <tapestry.nillehammer@...> To: "Tapestry users" <users@...> Sent: Monday, 29 June, 2009 15:31:04 GMT +02:00 Athens, Beirut, Bucharest, Istanbul Subject: Re: Override an IoC service Hi Peter, Isn't this a question of disambiguation of Services either with ids or with the@Local annotation as described here: http://tapestry.apache.org/tapestry5.1/tapestry-ioc/service.html ?

	Re: Override an IoC service by Thiago H. de Paula Figueiredo :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message I think that, in your scenario, service overriding is the best option, decoration being second (but a little more complicated to implement). -- Thiago --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@...
