Interceptors i ejb 3.0

[Lalit mishra]

1. If i use Interceptors for a bean
then the interceptors would be appliesd to all
business methods.

@mishra
Interceptors can have basically three access levels.
1. Application ie with ejb-jar file
This are called default interceptors. The affect all
classes with their methods. Can only be specify in DD.
But Classes and method can be configured to ignore it.

2. The next is Class interceptor, yap, once declared
it is applicable to all the class methods, again except
it is ignored using dependency injector or DD.

3. Method level, apply to the method in which it is applied.

Also not the the transition is addictive, ie if interceptors are applied
to the application(default), ame for all class methods.
Check the spec for more details.
Hope it helps.

You would normally use @Interceptors(...) annotation just before the class or the method.You can also achieve this using xml dd.

In the above (...) ... is a single argument which specifies the interceptor class.So it can be myInterceptor.class.
