2.x Quartz Example

This document describes how to run the Qaurtz example and provides details about what it does. For information on the business use case, please refer to: Use Case for Quartz.

The Quartz example illustrates the following:

  • use of declarative programming
  • how to use a Quartz timer
  • how to use tracing

The source code for the Quartz example is located in the ServiceMix installation directory under the examples\quartz-binding directory in the servicemix.xml file. It is recommended that you refer to the source code while reading this document.

This example shows how to use a Quartz component to set off a trigger that sends messages to a trace component. The trace component logs the messages to the console as they arrive

...

Stopping the Quartz Example

To terminate the Basic Quartz example type "CTRL-C" in the command shell in which it is running and answer "y" to the "Terminate batch job (y/n)?" question.

...

Messages flow through the components as follows:

  1. For every Every 5 seconds the timer component sends a message to trace through the Normalized Message Router (NMR).
  2. trace transforms the normalized message into a string and logs it to the console.
