Hi David,
Yes, you should be able to do this, although you may need to create
your own Bootstrapper implementation as opposed to
DefaultBootstrapper. Depending on what you want to do, you can either
create an in memory representation of the model, passing it to the
Deployer system service or you can create one of the subclasses of
SCAObject and pass it to CompositeComponent.register() if you want to
avoid the model altogether and do something like PicoContainer
(http://www.picocontainer.org/). If you opt for the latter you will
be responsible for wiring.
The above assumes you want to essentially create a custom runtime
distribution. If your goal is to dynamically bind something from some
type of instrumentation, then that would best be done through a
management API that hasn't been defined but which people have talked
about.
The custom runtime option will likely not work from application code
as the system classloaders are isolated. Also, in Dependency
Injection-based systems, I generally find dynamic binding to be an
anti-pattern that is best avoided through configuration.
Perhaps you could detail a little more what you are trying to do?
Also, if you wanted to talk about a potential management API, I know
several of us would be interested.

wondering,
Is there currently a way to pass the description of an SCA application
directly rather than passing the information through the defualt.scdl?
