We need to install the Seam jBPM-related components, and place the pageflow definitions (using the standard .jpdl.xml extension) inside a Seam archive (an archive containing a seam.properties file):

<bpm:jbpm />

We can also explicitly tell Seam where to find our pageflow definition. We specify this in components.xml:

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