[jboss-user] [EJB 3.0] - Circular call of beans, transaction context

[beep_beep]

I have 3 SfSB  : A,B,C

Bean A has method getBean(Class), 
this getBean(B.class) returns bean B,
then I call method doSomthing() on B, this method doSomthing has 
@TransactionAttribute(TransactionAttributeType.REQUIRED)
and doSomthing calls A.getBean(C.class) to achive C.

In this example bean A is factory, which is accessible from all beans and provides reference from one bean to another.

I tried to assign ALL existent attributes "TransactionAttribute" on method getBean(Class), but anyway I have this exception:

 
On this last call exception happens:

What happen here? Any attribute on getBean does not help! 
Thanks.
