Could you explain it plz ? I have the same problem and I really don't understand why...... I have this process: <process-definition xmlns="urn:jbpm.org:jpdl-3.2" name="process9"> | | <start-state name="start-state"> | <transition to="state1" name="to state1"/> | </start-state> | | <state name="state1"> | <transition to="state2" name="to state2"/> | </state> | | <state name="state2"> | <transition to="endstate" name="to endstate"/> | </state> | | <end-state name="endstate"/> | | </process-definition> When I start my JBoss, I try to launch my process with an EJB client: | public static void main(String[] args) | { | String nameProcess = "process9"; | | // Start a new process and go to state 1. | long processId = ManagementJBPMDelegate.launchProcess(nameProcess); | | // State 1 to state 2. | ManagementJBPMDelegate.signalProcess(processId); | } It works.... But, If i do: | public static void main(String[] args) | { | String nameProcess = "process9"; | | // Start a new process and go to state 1. | long processId = ManagementJBPMDelegate.launchProcess(nameProcess); | | // State 1 to state 2. | ManagementJBPMDelegate.signalProcess(processId); | | // State 2 to endstate. | ManagementJBPMDelegate.signalProcess(processId); | } It doesn't work, i have this exception: anonymous wrote : Exception in thread "main" javax.ejb.EJBException: org.jbpm.JbpmException: could not retrieve message connection factory | at org.jboss.ejb3.tx.Ejb3TxPolicy.handleExceptionInOurTx(Ejb3TxPolicy.java:77) | at org.jboss.aspects.tx.TxPolicy.invokeInOurTx(TxPolicy.java:83) | ... | Caused by: org.jbpm.JbpmException: could not retrieve message connection factory | at org.jbpm.msg.jms.JmsMessageServiceFactory.getConnectionFactory(JmsMessageServiceFactory.java:80) | at org.jbpm.msg.jms.JmsMessageServiceFactory.openService(JmsMessageServiceFactory.java:140) | ... | Caused by: javax.naming.NameNotFoundException: jms not bound | at org.jnp.server.NamingServer.getBinding(NamingServer.java:771) | at org.jnp.server.NamingServer.getBinding(NamingServer.java:779) but ... If I start my JSF-console and try to start a process9, from start state to end state, it works! Then, if i redo my main program which calls EJBs, it works .... :-/... Why ? Do you have any idea?
