h1. Features

\\
This component schedules jobs to trigger services invokations within the JBI bus. The jobs are based on time policies.

It is relying on the Quartz open source project.

This component only acts as a service consumer and doesn't act as a service provider. You use it to start another treatment managed by another service.

h1. Service Configuration

h3. Job scheduling

CONSUME SERVICE : Call a JBI service according to a time expression.

h3. Service Unit Descriptor

The Quartz component is configured with a cron expression, a service to call and an XML message request to send to the service.

You have to deploy a Service Unit with a JBI descriptor containing a consumes section and the parameters.

Here is a sample of a SU JBI descriptor to call a Hello service with <text>hello</text> message, at 10:15am every day during the year 2005 :
