This ebook delivers a lot, yet grants little. For starters, it has a number of errors--for instance, on web page 188, a number of instances it refers to "EJB" as "EBJ". probably that is trivial, yet, bankruptcy after bankruptcy, i discovered faults within the examples that avoided them from operating. Worst is the bankruptcy on Entity Beans--it incorporates a quite reliable reveal at the thought and perform of Entity Beans, however the instance includes no buyer code, no directions on mapping the Entity Bean to an underlying database, and no clue as to the relational tables that the Entity Bean accesses.

In different phrases, this booklet misplaced my belief. if you purchase it, learn it for the cast factors of the thoughts round jsp's, servlets, tag libraries, and EJB's--but do not anticipate the examples to paintings. and feature your atmosphere already arrange, simply because this ebook will not consultant you thru that.
