Jaikiran, I just tried the @Service notation:
| package ae;
|
| import javax.annotation.Resource;
| import javax.ejb.TransactionAttribute;
| import javax.ejb.TransactionAttributeType;
|
| import org.apache.log4j.Logger;
| import org.jboss.ejb3.annotation.Depends;
| import org.jboss.ejb3.annotation.Management;
| import org.jboss.ejb3.annotation.Service;
|
| @Service
| @Management(MasterMBean.class)
| @Depends( { "jboss.j2ee:jar=SubEJB.jar,name=CalculatorBean,service=EJB3" })
| public class Master implements MasterMBean {
|
| private static final Logger log = Logger.getLogger(Master.class);
|
| @EJB(mappedName = Calculator.JNDI_NAME)
| private Calculator additionBean;
|
| @TransactionAttribute(TransactionAttributeType.NEVER)
| public void start() throws Exception {
| log.info("### starting");
|
| if (additionBean == null) {
| log.error("### unable to inject CalculatorBean!!!");
| return;
| }
|
| long result = additionBean.add(new int[] { 1, 2, 3 });
| log.info(result);
|
| // TODO use a quartz job to run a calculation every 5 seconds!
| }
|
| public void stop() {
| log.info("### stopping");
| }
| }
|
After removing the master-mbean-jboss.xml and deploying the SAR into
server/all/deploy-hasingleton, the Injection worked pretty fine! But the old
approach still does not work. Can you tell me why?
Another thing: as you can see, I had to annotate the start() method, because I
got an Exception:

Why is that, actually? I don't have any problems when looking up the bean
manually
Greetings,
