add a depends clause to your jboss-service.xml file: <server> | <mbean code="org.jboss.varia.scheduler.Scheduler" name=":service=Scheduler"> | <attribute name="StartAtStartup">true</attribute> | <attribute name="SchedulableClass">com.acme.HelloWorld</attribute> | <attribute name="InitialStartDate">NOW</attribute> | <attribute name="SchedulePeriod">5000</attribute> | <attribute name="InitialRepetitions">-1</attribute> | <depends>EAR file name*</depends> | </mbean> | </server> | * check jmx-console for the name of the ear, or if you want your schedular to depend explicitly on a Session Bean View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3958081#...
