Hi all,
Being at the JAX conference now, I am quite oftenly confronted with the javax
vs. Jakarta discussion.
Besides that it is not clear how to handle that at the API level (btw. Good
blog entries, David and Mark), I am thinking of how it could be handled at
implementation level.
My preferred solution would be the complete separation of Java EE APIs (with
javax packages) and Jakarta EE APIs (with jakarta packages)
and having the implementation support both. The question is, are we able to
handle this without much code change?
My first idea was to define an own set of interfaces like
public interface Bean<T> extends javax.enterprise.inject.spi.Bean<T>,
jakarta.enterprise.inject.spi.Bean<T> {
…
}
We could then use this interface as return value for or interfaces whereever
Bean is the return value in specification interfaces.
The only problem I see with this approach seems to be with Collection return
values and generics, i.e. javax.enterprise.inject.spi.Bean#getInjectionPoints()
returns a Set<javax.enterprise.inject.spi.InjectionPoint> and
jakarta.enterprise.inject.spi.Bean#getInjectionPoints() would return a
Set<jakarta.enterprise.inject.spi.InjectionPoint>. In an ideal world our common
interface would return a Set<org.apache.openwebbeans.InjectionPoint> where
org.apache.openwebbeans.InjectionPoint extends the other InjectionPoints. But
that does not work for generics.
Regarding parameters the solution would be to have both methods and call one
from the other, wrapping the parameter, which most probably should work out.
Any ideas/opinions on that?
Cheers,
Arne
