Think about it, you got reference to EJBObject(component interface) through EJBHome. now you are in the middle of executing business method in that bean using EJBObject. Now think that you have lost reference to your EJBHome and you want to create another bean to do someother business operation. In this scenario, if this helper(getEJBHome()) method isn't there, again you need to go through JNDI to get reference to EJBHome. Intead you can use getEJBHome() method. This is the reason why? EJBObject has this getEJBHome() method.
