1.0 out of 5 stars Nearly Unreadable Study Guide., January 14, 2003

This review is from: Sams Teach Yourself EJB in 21 Days (Paperback)

I have to say that, having purchased this book, I am not a happy shopper.

SAMS two study guide series, the "24 hours" and "21 days" books, are usually fantastic value for money. On a quick scan of my bookshelf I see I have "Apache 2 in 24 hours" and "JDBC in 21 days" and they have both been invaluable to me.

What went wrong with "EJB in 21 days"?

On the plus side this book is comprehensive, the writers know their material and the order in which they tackle it is clear and logical.

On the minus side Ragae Ghaly and Krishna Kothapalli appear to share to deep aversion to clear, well-formed sentences. Here is an example, I challenge the reader to find the full sense of this sentence in less than three readings:

"The session context provides access to runtime session context such as identifying the caller, access or change current transaction state, and so on." (Day 3 p.58)

Even after three readings when the sense that the writers were trying to convey may actually congeal somewhere inside your brain it is difficult to convince yourself that this sentence is grammatically correct; surely that should be "...access[ing] or chang[ing] [the] current ...".

Sadly this is not an isolated example. At times the writers appear so confused by their own ramblings that they go over the same point several times in a row desparately trying to clarify what they have already muddied.

My advice to you: don't buy it.

My advice to SAMS: put your comissioning editor on punishment rations until he or she recovers his or her editorial zeal.

The book helped me to get fast into EJB, a lot of examples and easy language, it also covers some other J2EE concepts like JMS and JDBC.
