Samples

The Samples Gallery offers: Asynchronous beans - WebSphere Trader application, that illustrates how to implement a streaming stock ticker server and client

• Asynchronous beans
• Servlets
• JMS
• Session enterprise beans
• CMP 2.0 enterprise beans
• Message-driven beans (MDB)

This Sample uses several parts to maximize the utilization of a server:

Work	Runs Java EE context-aware code on a thread.
Alarm	Runs Java EE 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 Java EE 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.
