Alejandro Guizar [http://community.jboss.org/people/alex.guizar%40jboss.com] replied to the discussion "Case for using jBPM's PVM "naked"?" To view the discussion, visit: http://community.jboss.org/message/559279#559279 -------------------------------------------------------------- The PVM is meant to be the foundation on top of which multiple process languages can be implemented. Read the http://onjava.com/pub/a/onjava/2007/05/07/the-process-virtual-machine.html Process Virtual Machine article for the full discussion. The target languages actually include Java although this is not documented as extensively. The class org.jbpm.pvm.internal.builder.ProcessDefinitionBuilder from jbpm-pvm.jar provides a fluent interface for creating process definitions straight in Java without parsing any process  document. The interfaces in jbpm-api.jar in fact constitute the API for the PVM, aiming to be as  language-neutral as possible. Although not part of the API the process definition builder is relatively stable, it has not been touched in a while. In sum, yes, direct acess to the PVM is a valid, though advanced, use case. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/559279#559279] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
