@Joram Barrez
I see your reply in 2009, since then are there any further development or better ways to do this? i.e., "If that is a problem, you could write the php could, put a remote facade in front of it and call it from Java using webservice/REST/RPC/... technology."
Could you please provide some more pointers/link/example/docs to do this (using JBPM with webservices/REST/RPC calls)
Thanks
