Ejb refrences another ejb

I have two EJBs , EJB A references EJB B, both are deployed to the same server.

Each time I try to deploy EJB A it tries to register EJB B which is already deployed and registered which causes error: 

java.lang.IllegalStateException

Any idea how to prevent EJB A from registering the referenced EJB?

I am using NetBeans and JBoss 4.2.3 as well as EJB 3.0.

Did you solve this problem meanwhile? It seems as if I could have the same problem: stackoverflow.com/questions/7552929/… - Martin Thoma

If you use maven build you can use 

<scope> provided </scope>

in the pom file of maven of EJB A

Although I cannot imagine why you get an exception if your EJB A is singleton try the annotation @DependsOn on A to specify a dependency on B.
