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

[Pete Muir]

I'm a bit concerned about you scanning weld* jars - what are you trying to discover by doing this? Do you have a list of beans discovered this way?

BTW Wweld-extensions doesn't exist anymore.

No documented way to do this right now, but I'm also not sure of a good way to do this for the reasons below. We do need something though, I agree. Can you make a CDI issue for this, so it doesn't fall off our radar?

Thanks!

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?
