Jiva is an easy and elegant way to create and manage human-oriented workflows and are processed by a light-weight engine.

Example Workflow

<?xml version="1.0" encoding="UTF-8"?>
<workflow id="two-step-approval">
     <completeBy lang="xpath" expression="date:after($workflowInstance/createdOn,'3')"/>
	 <start>
	 	<transition id="request" to="approval"/>
	 </start>

	 <task id="approval">
	    <completeBy lang="time" expression="2 days"/>
        <assignment routing="sequential"> <!-- Sequentially route to every resolved user -->
            <handler>de.aedelmann.jiva.assignment.WeekdayAssignment</handler>
            <postprocessor>
                <processor key="addSubstitutes"/>
                <processor key="removeAbsent"/>
            </postprocessor>
            <completionPolicy>
                <allMatch transitionId="Approve"/> <!-- Transition 'Approve' is taken if everyone in sequence approves  -->
            </completionPolicy>

	 <task id="follow-up">
