Overview of the ServiceMix 1.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 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
Running the Quartz Example
From a command shell, go to the Quartz example directory:
cd [servicemix_install_dir]\examples\quartz-binding
Then type:
[servicemix_install_dir]\bin\servicemix servicemix.xml
where servicemix_install_dir is the directory in which ServiceMix was installed.
Stopping the Quartz Example
To terminate the Basic example type "CTRL-C" in the command shell in which it is running and answer "y" to the "Terminate batch job (y/n)?" question.
How it Works
The diagram below illustrates the flow of messages through the Quartz components.
Quartz Example Message Flow Diagram
Messages flow through the components as follows:
- For every 5 seconds the timer component sends a message to trace through the Normalized Message Router (NMR).
- trace transforms the normalized message into a string and logs it to the console.

Details
The following table provides more details about the function of each component and bean in the servicemix.xml file.
Component or Bean ID |
Description |
|---|---|
timer |
The timer component shows the use of the QuartzComponent class. Every 5 seconds, until the program is terminated, the timer component kicks off an instance of a SimpleTrigger, which is associated with an instance of JobDetail. The job has a property called "name" with a value of "My Example Job" and another property called "group" with a value of "ServiceMix." The resulting message is converted to a normalized message and routed through the NMR. |
trace |
Receives normalized messages via the NMR. It transforms the normalized message into a string and logs it to the console. |
