Yeah I though about this method, but it is rather complicated if I must 
initialize more complicated data structures. For example if I have beans 
OWNER,DOG,AWARD, where relation is - owner have many dogs, dog have many 
award. If I use lazy initialization I can easy print out everything. But 
I resign from lazy loading I must initialize collections by hand. So If 
have a owner I should initialize DOGS Collection. It is easy -> 
Hibernate.initialize(owner.getDogs()). But in next step I want to 
initialize all dog awards, to do that I must Iterate through getDogs 

Iterator<Dog> it = owner.getDogs().iterator();
while (it.hasNext())  Hibernate.initialize(;

So it is bit more complicated. But if we have more nested elements we 
want access the initialization become madness. So I think it is not 
worth to resign from lazy loading.
