Application server components

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.
