h1. Scheduling service invocations (Consumes mode)

h2. Usage

Since this component only supports consuming configurations, no WSDL is required.
However, the messages sent by this component must respect the WSDL of the invoked service.
One way to ensure that is to generate the message's XML skeleton from the WSDL of the target service.
A tool like SoapUI works well for this kind of task.

The messages sent by this component are sent with the *InOnly* pattern.
It is not possible to add file attachments in the sent messages. These messages only have an XML payload.
This message is sent every time the time expression is reached.

Time expressions are CRON expressions. The syntax is explained on the [website of the Quartz project|http://www.quartz-scheduler.org/]. This Petals component is based on Quarts version 2.3.0.
Below are given some sample CRON expressions and their meaning.

h2. JBI Descriptor

The Quartz component is configured with a CRON expression, the identifiers of 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 with the right 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.
{code:lang=xml}<?xml version="1.0" encoding="UTF-8"?>

<jbi:jbi version="1.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:jbi="http://java.sun.com/xml/ns/jbi"
xmlns:quartz="http://petals.ow2.org/components/quartz/version-1"
xmlns:petalsCDK="http://petals.ow2.org/components/extensions/version-5"
xmlns:generatedNs="http://petals.ow2.org/components/hello/version-3.0">

<jbi:services binding-component="true">

</jbi:services>
</jbi:jbi>
{code}

A JBI descriptor for a Quartz service-unit can only define one _consumes_ block.
