How to validate XML commands that are sent to JobScheduler

Introduction

JobScheduler provides an XSD schema that documents the available elements and attributes of the XML Interface:

• the XML commands
• the configuration of JobScheduler objects such as jobs, job chains, orders
• the configuration of the JobScheduler start-up file ./config/scheduler.xml

The XSD Schema is available at https://download.sos-berlin.com/schema/jobscheduler/jobscheduler-version-1.3.xsd

Usage Patterns

JobScheduler and JOE

• JobScheduler itself uses the XSD schema to validate input from configuration files and from the XML interface.
• JOE validates configuration files on start-up and when content is being saved.

Customer applications

• Individual customer applications make use of the XML Interface in order to e.g.
  • add orders for job chains,
  • start jobs and orders.
• Example

  • An application or database trigger could use the XML Interface to send a command such as

    <add_order job_chain="my_folder/my_job_chain" at="now+60">
      <params>
        <param name="reminder_date" value="2014-11-21"/>
      </params>
    </add_order>

• Such applications can use the XSD schema to validate commands before sending them to JobScheduler.
