Another way of looking at it is some people's explanations of technical topics are better than others.
We've all , at some time, probably read a tech book that we didn't get that much out of.
I've read one of Budi's earlier books that covered
J2EE . It was well written.
I can confirm it provided me with a clear understanding of the entire process and how the parts (EJB's,Servlets ,Jsp's) fit together and what they did .
