Hi echo, I have updated the RF example project in the evo experiments repo to use guice [1]. As you can see, with this approach 1.- We dont need Locators for domain objects anymore, since guice will create the appropriate implementation (this saves a lot of glue code) 2.- All client services shares the same Locator so as we use again guice to select the suitable service implementation. 3.- Note that you have service decorator which is shared in prod and test code.
I think it is the best pattern for Hupa - Manolo [1] http://code.google.com/a/apache-extras.org/p/hupa-evo/source/detail?r=46# On Wed, Jul 18, 2012 at 9:29 AM, echo <echo...@gmail.com> wrote: > Thanks a lot. > > > On Wed, Jul 18, 2012 at 2:54 PM, Manuel Carrasco Moñino <man...@apache.org > > wrote: > >> You can take advantage of this code and use Locators to get your service >> classes injected.
