An interceptor class shares the enterprise naming context of its associated target class. Annotations and/or XML deployment descriptor elements for dependency injection or for direct JNDI lookup refer to this shared naming context.
Around-invoke and around-timeout interceptor methods run in the same Java thread as the associated target method. Around-construct interceptor methods run in the same Java thread as the target constructor.
It is possible to carry state across multiple interceptor method invocations for a single method invocation or lifecycle callback event in the context data of the InvocationContext object. The InvocationContext object also provides information that enables interceptor methods to control the behavior of the interceptor invocation chain, including whether the next method in the chain is invoked and the values of its parameters and result.
