invoking method within same EJB

[deepak yadav]

I have 2 methods in my EJB, testA and testB. I have to invoke testB from testA and that I can do in 2 ways:
i) directly invoke testB from testA, like a class method
ii) create a remote object of this EJB and then invoke testB on this remote object
Is there any difference between the two in the way
o transactions are handled
o underlying security framework applies restriction
o any other thing apart from probably less overhead in (i)
thx
