[cdi-dev] CDI 1.1 EDR1 posted :-)

[Mark Struberg]

What do you exactly mean with JavaSE contexts?
Do you mean that we should _explicitely_ declare that @ApplicationScoped, @RequestScoped and @SessionScoped must be active by default in SE apps?


In OWB and CODI we we provide the same contexts for both SE and EE already. But their behaviour is slightly different.

This is really a big benefit not only for SE apps, but also when it comes to unit testing, as you don't need to boot a whole container. Arquillian is pretty fast already, but doing it 'native' is still 10 times faster.

In OWB/CODI we started have something like the following in our Extension which registers our scopes 


if (projectStage = ProjectStage.UnitTest) {
  registerDummyScopes()...
} else {
  registerRealScopes();
}

where the dummy scopes are just dumb Maps per Thread.


And sometimes we just have a Context Facade which gets the 'real' context implementation as a 

@Dependent MyContextImpl

bean. In codi-core-impl we just provide a pure SE only implementation, in codi-jsf12-impl we provide a 


@Specializes @Dependent
Jsf12MyContextImpl extends MyContextImpl

and in codi-jsf20-impl an 

@Specializes @Dependent
Jsf20MyContextImpl extends Jsf12MyContextImpl

This works pretty well because the context registration is only done in @Observes AfterBeanDiscovery, thus you can fully use CDI itself in the Contexts. 

The only thing you must take care is that internally used Contexts got registered before your own. E.g. the CODI @RestScoped an @WindowScoped storage internally,
thus @WindowScoped must get registered upfront.


Means, technically it is easily doable, but it's some homework to do for Containers and Extensions.
