Now not a nasty publication, to be reasonable, yet from a complicated developer's perspective, i have to say: "just one other tutorial". The authors take us at the ordinary journey from effortless to medium complex examples, protecting a few flooring that's in most cases attention-grabbing for builders who're simply starting with Seam.
What they're (almost) now not doing is to take the reader behind the curtain and canopy a few complex issues. Many chapters gave the impression of a blown content material of the to be had on-line documentation to me, not anything relatively new, not anything relatively unique.
"Seam in motion" by way of Dan Allen is the much better deal. He provides an perception from a Seam middle developer's standpoint, that is through way more interesting.
If i would not recognize "Seam in Action", i'd suggest this e-book to rookies in Seam.
I certainly don't suggest the publication to an individual in desire of discovering solutions to complex themes (architectures, styles, go slicing issues in complicated company scenarios).
This e-book is the main whole and up to date source on Java from programming guru, Herb Schildt -- essential table reference for each Java programmer.
