In this example we see that the @Depends annotation contains the JMX name of the stateless bean that we are dependent upon.
For example: jboss.j2ee:ear=dummyEar.ear,jar=dummyJar.jar,name=DummySLSB,service=EJB3

consists of:
jboss.j2ee: # our domain
ear=dummyEar.ear #containing deployment unit
jar=dummyJar.jar # the application container
name=DummySLSB # the name of the service
service=EJB3 # the service type
To find out these values its best to look at http://localhost:8080/jmx-console/ when the jboss is up.
