OK. I found my problem: 2 files were to be added in META-INF - scheduler-service.xml having the tag <mbean code="org.jboss.varia.scheduler.Scheduler" ...> described above - jboss-app.xml with <jboss-app> | <module> | <service>META-INF/scheduler-service.xml</service> | </module> | </jboss-app> And these 2 files must be added in eclipse packaging configuration page in the Project.ear node with the prefix META-INF Finally works for me: a message appears at 3 secconds in the console window.
