Services are started before EJBs, therefore the EJB is probably not ready at the time the code is run. You need to add a depends tag that references the BMean generated for the EJB. Something like this: <mbean ...> | <depends>jboss.j2ee:ear=xxx.ear,jar=xxx.jar,name=MyEjb,service=EJB3</depends> | </mbean> You can use the jmx console to look up the name for your ejb's mbean.
