Ejb interceptor and CMT transaction

Question

hi all,
i have one stateless session bean using CMT.
And it has been intercept by ejb interceptor.
actually, i try to catch all the exception from session bean method using interceptor.
eg.
try {
target2 = invocation.proceed();
return target2;
} catch (Exception e) {
But i can't catch some kind of SQLException. because it looks like transaction doesn't commit after invocation.proceed();
So, i can only catch those exception from caller.
Is there any way to solve it?
is there any way to catch all the exception from interceptor ?

Thanks for reply.
we do not support to use requires_new because we may have another ejb layer(caller) and our ejb may need to join transaction of caller.
So, i would like to choose EntityManager.flush().
Then, I have DAO layer to insert record to db. Something like generic DAO and it is supported for all kinds of entity.
So, when we invoke two times DAO layer from our stateless session bean method, how it will behave?
I mean in the following ejb method, both DAO call can be in same transaction?
eg. DAO
public void create(T t) {
entityManager.persist(t);
entityManager.flush();
EJB Method
@TransactionAttribute(value = TransactionAttributeType.REQUIRED)
public void performInsert(){
dao.create(EmployeeEntity);
dao.create(AddressEntity);
}
