beginer question - @remote adn pass by value

[kanto]

hi, i have some basic question.

suppose i have 2 beans implementing remote interface.
from bean1 i invoke method on bean2 in which i pass some POJO object(persistant). In remote beans object are passed by value ,right ??
so if i want to retrieve changes made in bean2 method i have to pass my object back from bean2 ??
eg.

Account a = new Account();
a.setSomething("asdf");

a = bean2.changeAccount( a );
^^^
this retrieves changed object.

System.out.print(a.getSomething());

is there another way of retrieving changes made in bean2 ??
