More info can be found here : http://www.orbeon.com/ois/doc/processors-other and here : http://www.orbeon.com/ois/doc/reference-listeners . But basically you need 1. In web.xml specify load on startup. e.g. <servlet> <servlet-name>oxf</servlet-name> <servlet-class>org.orbeon.oxf.servlet.OXFServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> 2. Make sure the context listener is specified. e.g. <listener> <listener-class>org.orbeon.oxf.servlet.OXFServletContextListener</listener-class> </listener> 3. Specify processor to run on context init. If you are only scheduling the xml below would suffice. <context-param> <param-name>oxf.context-initialized-processor.name</param-name> <param-value>{http://www.orbeon.com/oxf/processors}scheduler</param-value> </context-param> <context-param> <param-name>oxf.context-initialized-processor.input.config</param-name> <param-value>oxf:/config/schedule.xml</param-value> </context-param> 4. Specify the schedule. <config> <start-task> <name>Task Scheduled From Context Initialization Pipeline</name> <start-time>now</start-time> <interval>10000</interval> <synchronized>true</synchronized> <processor-uri>oxf/processor/pipeline</processor-uri> <input name="config" url="oxf:/scheduled-task.xpl"/> </start-task> </config> A small example is in the attached zip file. Also the examples in orbeon.war, what used to be oxf.war, show this is well. To see it in action you need to uncomment the apropriate listener sections in web.xml.
