Beginning Google Web Toolkit: From Novice to Professional by Bram Smeets PDF

By Bram Smeets

The ebook is easily written yet is now extraordinarily old-fashioned. The e-book used to be written for GWT model 1.5, yet on the time of my buy GWT 1.7 was once the newest unencumber. there have been extra changes than I anticipated. in exactly the 1st 3rd of the ebook i discovered the following:

- applicationCreator.cmd isn't any longer a GWT command. it's been changed through webAppCreator.cmd

- webAppCreator.cmd creates a special listing constitution than the illustrated examples.

- The default program that GWT generates has changed.

- a brand new occasion version used to be brought in GWT 1.6. particularly, Listeners are changed with Handlers. you'll stumble upon this for the 1st time in bankruptcy three.

- whereas i used to be following the routines utilizing GWT 1.7, Google published GWT 2.0 which additional obsoleted this variation. The 2.0 unencumber brought a declarative UI with UIBinder. in fact that may not be during this publication. additionally in 2.0 "Development Mode" changed the "Hosted Mode" that's nice yet will confuse the beginner utilizing this booklet as guidance.

The merely means this ebook will be priceless is that if you obtain GWT 1.5 to persist with in addition to the examples. i do not recognize many programmers, amateur or in a different way, that might be content material to profit a know-how on an previous unlock with deprecated equipment and out of date tooling.

I just like the narratives of the e-book, i love how it flows, and if the authors ever choose to submit a brand new variation with GWT 2.0 with an identical variety and accuracy it'll most likely earn 5 stars. regrettably the booklet is simply too many releases outdated (which is simply too undesirable contemplating it was once simply Copyrighted in 2008!)
