Apart from the "interesting" use of the English language in this book, which makes it hard to read, it consists mostly of useless lists of classes and APIs. It provides nearly no useful background or introduction, and where it does, the author's insufficient language skills get in the way.
At first, I gave the book the benefit of doubt, but even with deep Liferay knowledge, it is a confusing and in large parts useless tome.
