[jboss-user] [Management, JMX/JBoss] - @depends annotation

[Renen]

Hello,

I have two annotated POJOs: ProcessManager and Logger. And, Logger depends on ProcessManager.

Try as I might, they seem to deploy in the wrong sequence:


  | 22:38:41,148 INFO  [STDOUT] Logger start
  | 22:38:41,154 INFO  [STDOUT] Process manager starting...
  | 

Which I don’t understand.

The annotations are as follows:


  | @Service (objectName="121:service=processManager")
  | @Management(ProcessManager.class)
  | @TransactionAttribute( TransactionAttributeType.NOT_SUPPORTED )
  | public class ProcessManagerMBean implements ProcessManager {
  | 	
  | 	public void start() throws Exception {
  | 		System.out.println("Process manager starting...");
  | 

And:


  | @Service (objectName="121:service=logger")
  | @Depends ({"121:service=processManager"})
  | @Management(Logger.class)
  | @TransactionAttribute(TransactionAttributeType.NEVER )
  | public class LoggerMBean implements Logger {
  | 	
  | 	public void start() throws Exception {
  | 		System.out.println("Logger start");
  | 

I have also tried injecting the dependency:


  | @Service (objectName="121:service=logger")
  | //@Depends ({"121:service=processManager"})
  | @Management(Logger.class)
  | @TransactionAttribute(TransactionAttributeType.NEVER )
  | public class LoggerMBean implements Logger {
  | 	
  | 	@Depends("121:service=processManager")
  | 	public ProcessManager processManager;
  | 	
  | 	public void start() throws Exception {
  | 		System.out.println("Logger start");
  | 

The injection happens, but the dependency is not managed.

The wiki indicates that the start() methods should be called in dependency sequence...

The complete extract of the logs is below.

Any pointers would be warmly received!

Thank you.
