Since every component of the toolkit works within the J2EE framework, the startup beans are able to do the initialization for some toolkit component such as CHA, the business processes, the Formatter, and services. Each of these components uses one or more startup beans to do the initialization before the component starts. The business processes, the Formatter, and services use the BTTStartup component, and the CHA uses two individual startup beans (see CHA startup beans).
The stop() method of startup beans in the toolkit does nothing when the components stop.
