In this tutorial you will learn how to configure EJB Interceptors used to – as the name states – intercept calls to EJB methods.

Another usage example may be to check if the client is authorized to call a given EJB method. Interceptors may be configured to intercept specific EJB method calls or to intercept calls to any method from a given EJB.
