�uncommon� methods declared in the javax.ejb.EJBContext interface
posted 11 years ago
I understand that we only have a method in a parent class/interface only if it is a common method for all its children class/interface.
But then why are there so many �uncommon� methods declared in the javax.ejb.EJBContext interface ?
getEJBHome(), getEJBLocalHome()... can�t be used by MDB (because MDB has no client interfaces like home and component interfaces).
getUserTransaction() can�t be used by EB (because EB must use CMT).
Don't get me started about those stupid
Please help me to understand interfaces
difference between abstract class and interface?
