I am reading <<Head First EJB
>> to prepare test
of SCBCD. There are some mock test with qnswer in the book. In some answer, it askes reader to refer to "spec: xx", for example, refer to "spec: 30". I download EJB 2.0 specification. It is pdf file with 572 pages. But, I can not find the items like "spec 30", "spec 25", etc.
My question are:
1. Where I can find the "spec: xx"?
