This section describes the changes to the application server components
due to the new architecture.
Many toolkit components that used to run in application server are removed
or significantly changed:
- Flow processors
- The flow processors do not exist in application servers now. Flow processors
are replaced by business processes. Through the Client/Server interfaces,
toolkit clients passes requests to an invoker or a WSIF Action that calls
the Business Process Component or Single Action EJBs in the application logic
layer.
- Server operations
- Operations do not exist in application servers now. Stepped operations
are replaced by business processes, and non-stepped operations are replaced
by business processes or Single Action EJBs. Through the Client/Server interfaces,
toolkit clients pass requests to an invoker or a WSIF Action
that calls the Business Process Component or Single Action EJBs in the application
logic layer.
