This not specifically a web service for command API of jBPM but... the JBoss ESB has implemented core jBPM 3.2.x which means you can expose jBPM APIs (deploy, create/start, signal, update vars) as JBoss ESB Services. JBoss ESB Services can be exposed to the outside world as JMS, FTP, File drop, WS, etc. So for example, you can start a new process instance via an FTP event (e.g a new order arrives on our FTP server), signal the process instance via a WS and update the process vars via a JMS message. At least this is the goal and the code is in place, just requires more feedback from users. Burr View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4088424#...
