The default messaging provider uses the
service integration bus for transport. The default message provider
provides point-to-point functions, as well as publish and subscribe
functions. Within this provider, you define JMS connection factories
and destinations that correspond to service integration bus destinations.

The Accessing Samples topic
offers:
- Asynchronous beans - WebSphere Trader
This Sample illustrates
how to implement a streaming stock ticker server and client using
asynchronous beans and J2EE services such as:
- Servlets
- Java Message Service (JMS)
- Session enterprise beans
- Container-managed persistence (CMP) 2.0 enterprise beans
- Message-driven beans (MDB)
This Sample uses several parts to maximize the utilization
of a server:
- Work - Runs J2EE context-aware code on a thread.
- Alarm - Runs J2EE context-aware code at a given time interval.
- EventSource - A method of broadcasting events to registered listeners.
- SubsystemMonitor - A thread that monitors the status of any asynchronous
system and uses an EventSource method to inform registered listeners
of the system status.
- WorkManager - Thread configuration and J2EE context policies that
are used by various asynchronous beans parts.
- AsynchScope - A collection of alarms, subsystem monitors and other
asynchronous scopes that support relationships. This collection utilizes
a single WorkManager thread and is also an event source.
- Startup Bean - A specialized, stateful session enterprise bean
that supports bootstrapping asynchronous work when the application
starts.
