XFire is a component based framework.

XFire: This is point of access for transports. Here you can invoke a service by providing an XML SOAP document and get the response programmatically.
Service: This is a description of a SOAP service.
Invoker: An Invoker allows you to controller the mechanism by which the underlying object that services a request is created.
ServiceRegistry: A registry of all the services within the system.
Handler: A processing module within XFire. This could do anything from processing an incoming XML stream to accessing your database.
TransportManager: Manages the transports within XFire. Custom transports should be registered here. It also has the ability to turn off/on transports for certain services.
Transport: An encapsulation of a transport mechanism, such as HTTP or JMS. A transport is responsible for managing incoming and outgoing communications using a particular wire protocol.
