We need to install the Seam jBPM-related components, and tell them where to find our pageflow definition. We can specify this Seam configuration in components.xml.

<core:jbpm>
    <core:pageflow-definitions>
        <value>pageflow.jpdl.xml</value>
    </core:pageflow-definitions>
</core:jbpm>

The first line installs jBPM, the second points to a jPDL-based pageflow definition.
