If you replace these three jars with jBPM 5.3 ones - then it looks ok. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/795001#795001] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
