Pete Muir updated WBRI-280:

    Fix Version/s: 1.1.0.BETA1

Takeshi, I'm putting this in the 1.1.0 bucket just because we need to concentrate on the spec for now - I like the idea, but we should discuss on the webbeans-dev list.

> In guice , If a type is needed but there isn't an explicit binding, the injector will attempt to create a Just-In-Time binding.(http://code.google.com/p/google-guice/wiki/JustInTimeBindings)
> However, If a type is needed but there isn't an explicit binding, WebBeans's BeanManager  throws UnsatisfiedResolutionException.
> If a type is concret class, BeanManager can create and inject a instance.
> I want to use injection as instance creation. because of keeping simplicity of code.
> Writing beans.xml is laborious.
