[seam-dev] Identifying which jars contains seam/cdi extensions and programmatic extensions ?

[Alexey Kazakov]

We are going to support Seam 3 extensions (such as @Veto, generic, ...) 
so we don't need to have some extra meta for such beans.
We are going to look at 
META-INF/services/javax.enterprise.inject.spi.Extension and handle all 
the known extensions properly.
But is it enough for Seam 3? For instance for weld we had to scan 
*weld*.jar's in a special way since they don't have beans.xml. But some 
of those beans we should not load (for example we don't load 
weld-extensions*.jar). How we supposed to recognize such beans in design 
time? Is there any documented way to do it?
