This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
Could someone explain to me the difference between the following(From EJB3.0 Core specs):
-A reference to an enterprise beans business interface
-A reference to an enterprise beans remote interface.
-A reference to an enterprise beans local interface.
I thought there was only 2 kinds of interface..local and remote.What does the 1st one refer to...?
What is the difference between retrieving an EJBObject\EJBLocalObject as opposed to calling get BusinessObject(Class <T> businessInterface)?Are there differences in capabilities of the returned object or what?
Duran Harris wrote:Oh ok so we're actually supposed to refer to the remote interface as the 'business interface' in EJB3.0 to avoid confusion with EJB2.x?
If the bean exposes a EJB2.x view through an interface extending the EJBObject or through the <remote> element in the xml, then that interface is known as the remote (component) interface.
If the bean exposes a EJB3.x view through an interface marked with @Remote or <business-remote> element in the xml, then that interface is known as a remote (business) interface.
