thx for the response kukeltje Sorry for the code, this is the code I'm testing | <?xml version="1.0" encoding="UTF-8"?> | | <process-definition | xmlns="" name="exempde"> | <start-state name="start"> | <transition name="debuter" to="identification"></transition> | </start-state> | <task-node name="identification"> | | | | | <task name="identify"></task> | <transition name="evaluate" to="evaluer"> </transition> | </task-node> | <decision name="evaluer"> | <transition name="winner" to="winner"> | <condition>#{nom == 'ettaib'}</condition> | </transition> | <transition name="loser" to="loser"> | <condition>#{nom == 'waterman'}</condition> | </transition> | </decision> | <task-node name="winner"> | <task name="win"></task> | <transition name="fin1" to="end1"></transition> | </task-node> | <task-node name="loser"> | <task name="lose"></task> | <transition name="fin2" to="end1"></transition> | </task-node> | | <mail-node name="send email" to=&#39;ettaib_m(a)hotmail.com&#39; subject="readmylips" text="nomoretaxes"> | <transition to="the next node" /> | </mail-node> | | <end-state name="end1"></end-state> | </process-definition> | Well actually I installed the jBossMailServer 1.0M4 and I configured it as shown in: http://wiki.jboss.org/wiki/Wiki.jsp?page=HowToInstallJBossMailServer1.0M4 But there is still a problem, when I run the tomcat server (or the jbpm server), I got exceptions and the application does not work at all, souldn't I run both of them in the same machine? Please send me code of your process def that you've tested. I'm looking dorward to your answer Thank you View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4070199#...
