what is local no-interface view?

[johndoe444]

In the J2EE tutorial from sum site, it is often mentioned this term. For example, the timersession example:

"Because it's a business method, setTimer is exposed to the local, no-interface view of TimerSessionBean and can be invoked by the client."

Thanks.

learn about the different ways EJBs can be invoked and you'll know.

Accessing Local Enterprise Beans Using the No-Interface View

Client access to an enterprise bean that exposes a local, no-interface view is accomplished through either dependency injection or JNDI lookup.

*

To obtain a reference to the no-interface view of an enterprise bean through dependency injection, use the javax.ejb.EJB annotation and specify the enterprise bean’s implementation class:

@EJB
ExampleBean exampleBean;

*

To obtain a reference to the no-interface view of an enterprise bean through JNDI lookup, use the javax.naming.InitialContext interface’s lookup method:

ExampleBean exampleBean = (ExampleBean)
InitialContext.lookup("java:module/ExampleBean");

Clients do not use the new operator to obtain a new instance of an enterprise bean that uses a no-interface view.
