WebFlow Component Model
WebFlow system comprises a hierarchy of CORBA objects that implement interfaces defined in java.beans.beancontext (Java 1.2):
- A WebFlowContext object implements an extended BeanContext interface. It maintains a persistent state, controls its children life-cycle, and is responsible for inter-JVM communications through a custom event model. The master (“root”) context maintains a hierarchy of proxy objects to facilitate communication with clients implemented as Java applets without violating the sandbox restrictions.
- A WebFlow Module implements BeanContextChild interface, is stateless (more precisely, it maintains a conversational state), and has access to all data maintained by its parent context.
Although implemented differently, conceptually close to EJB and CORBA 3 Components models.
