Avalon is a Component framework that specifies the contracts for Components and how
they work together.
SOAP is a protocol to process requests based on XML markup.
EJB is Sun's version of remote server side components that allow you to separate
database integration between the components and database structure.
EJB does not know anything about Avalon's Framework, but Avalon can be used to
create an EJB engine.
If you want to create a standalone application that interfaces with EJB, you can
use Avalon for the framework for your application, and interprets SOAP requests.
It will then make calls to your EJB server.
