The EJB 3.0 spec defines the ability to apply custom made interceptors to the business methods of your session and message driven beans (and of course to the JBoss @Service and @Consumer beans). EJB 3.0 interceptors take the form of methods annotated with the @javax.ejb.AroundInvoke annotation. This JavaPolis talk by Bill Burke covers this part of the EJB3 spec.
Bill Burke is CTO of JBoss Group. Bill fell in love with middleware when he was introduced to DCE while at the parent company of Open Environment Corporation. He later went on to being a core member of the Orbix2000 team at Iona, where he helped them build some of their CORBA products. After weathering a few failed internet startups building J2EE applications, Bill stumbled into JBoss and helped them with their clustering architecture and EJB container. Now, as lead architect of JBoss 4, his main focus is on bringing AOP concepts and technology to the JBoss application server. Bill is co-author of O'Reilly's "JBoss 3.2 Workbook", and has numerous other in-print and on-line publications. He graduated magna cum laude with a B.S.C.S. from Northeastern University in Boston in 1994. In his spare time, now that JBoss is the full-time job, Bill likes to hang with his wonderful wife and is a rabid football fan being a New England Patriots season ticket holder for the past 10 years.
