how to wrap tapestry.services.FactoryServices?
Hi --
I am trying to wrap some engine service by replacing the configuration
point, tapestry.services.FactoryServices with this definition:
<contribution configuration-id="service:tapestry.services.FactoryServices">
<service name="home" object="service:tapestry.services.Home" />
<service name="direct" object="service:transactionalDirectService" />
<service name="page" object="service:transactionalPageService" />
<service name="reset" object="service:tapestry.services.Reset" />
<service name="restart" object="service:tapestry.services.Restart" />
<service name="asset" object="service:tapestry.services.Asset" />
<service name="external" object="service:tapestry.services.External" />
</contribution>
I did something similiar to this to replace
tapestry.services.ResponseContributors:
<contribution configuration-id="tapestry.services.ResponseContributors">
<invoker object="service:ScriptResponseContributor" />
<invoker object="service:tapestry.services.JSONResponseContributor" />
<invoker
object="service:tapestry.services.DojoAjaxResponseContributor" />
<invoker
object="service:tapestry.services.DefaultResponseContributor" />
</contribution>
but for the factoryservices I get :
Error building service transparentpolitics.sessionFactory: Error at
context:/WEB-INF/hivemodule.xml, line 76, column 87: Unable to
construct service tapestry.services.ServiceMap: Error building service
tapestry.services.ServiceMap: Error at

line 159, column 81: Unable to initialize service

line 53, column 54.
Does anyone have any ideas on how I can do this service wrapping?

The following snippet of tapestry.services.xml (from
Tapestry-framework-4.1.jar) suggests that to override the factory
services you should add services with the same ID of the ones you want
to override to the configuration point
tapestry.services.ApplicationServices.
Maybe an interceptor is more appropriate for your needs, i don't know
much about interceptors (yet).
----- snippet from tapestry.services.xml ---------
<configuration-point id="ApplicationServices" schema-id="EngineServices">
Configuration point for application services. Each contributed service
must have a unique name, but services contributed here will override
services provided in the FactoryServices configuration point.
</configuration-point>

It sounds like you are not allowed to "contribute" more than one
service name with the same id for this particular configuration point.
Maybe what you need to do is define what object is returned from the
tapestry.services.Home service point via
http://hivemind.apache.org/descriptor.html#implementation .
Of course it sounds like a much easier option might be to use an
interceptor to just wrap all of the core services, if that's all you
needed to do. http://hivemind.apache.org/descriptor.html#interceptor

Hi there --
Thanks for pointing out the ApplicationServices configuration point.
That did it.
I still don't understand why the method that I was trying failed.
The interceptor stuff seems like way overkill in the specification
department to really want to use.

Yes, thats probably a good way to do the "wrapping"...

Actually, as i understand it, if you contribute to
tapestry.services.ApplicationServices, you can override a specific
service used by tapestry with your own and still have in the registry
the original provided by tapestry.
e.g.: I want to override Home service so it uses my own
HomeServiceWrapper class...
In my hivemodule.xml i would put:
<service-point id="HomeWrapper" interface="IEngineService">
<invoke-factory>
<construct class="HomeServiceWrapper">
<set-object property="wrappedService"
value="service:tapestry.services.Home" />
</construct>
</invoke-factory>
</service-point>
<contribution configuration-id="tapestry.services.ApplicationServices">
<service name="home" object="service:HomeWrapper" />
</contribution>
I did not test it, but i'm fairly confident it would work. Please
correct me if i somehow forgot something, i'm still getting used to
hivemind.

I don't get exactly what you want to do by "wrapping".
You can replace an implementation of a service by providing another
implementation, but then the old one will not exist in the registry anymore.
But it sounds more what you need is to intercept the services - take a
look at hivemind interceptors...
