Samples

The Samples Gallery offers:

• Asynchronous beans - WebSphere TraderThis Sample illustrates how to implement a streaming stock ticker server and client using asynchronous beans and J2EE services such as:
  • Servlets
  • 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 uses 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.
