The component configuration file is a XML file containing configuration information for the instantiated Avalone services.
For finding the right section of the component configuration file the shorthand of the role configuration is used - in our case "SystemPropertyService". Here we define a system property with the name "FOO" and the value "BAR".
<componentConfig> <SystemPropertyService> <property name="FOO">BAR</property> </SystemPropertyService> </componentConfig>
