Hi, His is possible in a jPDL workflow to have the following ? <step1>-<step2>-<JMS queue 1>-<JMS queue 2 / with some matching UID>-<step 4>-<step5> With something completely different and external, consuming JMS queue 1 and posting into JMS queue 2? If such type of JMS interaction is not possible, does is exist a "default" way to deal with external asynchronous treatment and jPDL workflow ? Thanks in advance for your answers, fliot View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4141075#...
