| * 1. INIT_EVENT: Server is initializing subsystems and setting up the runtime environment. |
| * 2. STARTUP_EVENT: Server is starting up applications |
| * 3. READY_EVENT: Server started up applications and is ready to service requests |
| * 4. SHUTDOWN_EVENT: Server is shutting down applications |
| * 5. TERMINATION_EVENT: Server is terminating the subsystems and the runtime environment. |
| * |
| * In this sample, on STARTUP_EVENT, a thread is started which sends a simple JMS message to |
| * sampleTopic every minute. On SHUTDOWN_EVENT, this thread is stopped. |
