EJBs depends on each other

trouby Jul 20, 2007 9:42 AM

Hey,

I have an 'MBeans waiting for other MBeans' error produced by Jboss without any other errors around,

I started to remove EJBs and the error disappeared,
I think found the part that makes the trouble, I have EJBs that depends on each other. so in each of the EJB, I inject the other one with the @EJB annotation,

What should I do when each EJB depends on the other one?
Is that not allowed? Glassfish and other appservers allow that without a problem, or there's another way to solve this problem?

here's how complete error from server.log:

Try annotating one with @IgnoreDependency as well as @EJB...

I have many cases of co-dependent beans, but so long as your dependency is not required in @PostConstruct, you should be OK...
