The publication is definitely written yet is now extraordinarily old-fashioned. The ebook used to be written for GWT model 1.5, yet on the time of my buy GWT 1.7 used to be the newest free up. there have been extra alterations than I anticipated. in precisely the 1st 3rd of the publication i discovered the following:

- applicationCreator.cmd is not any longer a GWT command. it's been changed via webAppCreator.cmd

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

- The default software that GWT generates has changed.

- a brand new occasion version was once brought in GWT 1.6. particularly, Listeners are changed with Handlers. you'll come 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 version. The 2.0 free up brought a declarative UI with UIBinder. in fact that may not be during this e-book. additionally in 2.0 "Development Mode" changed the "Hosted Mode" that is nice yet will confuse the beginner utilizing this publication as guidance.

The simply method this e-book will be useful is that if you obtain GWT 1.5 to stick to in addition to the examples. i do not be aware of many programmers, amateur or another way, that may be content material to profit a know-how on an outdated unencumber with deprecated tools and out of date tooling.

I just like the narratives of the booklet, i admire how it flows, and if the authors ever choose to put up a brand new variation with GWT 2.0 with a similar type and accuracy it will most likely earn 5 stars. regrettably the ebook is simply too many releases old-fashioned (which is simply too undesirable contemplating it used to be simply Copyrighted in 2008!)

And as we discussed, writing and maintaining JavaScript applications is an entirely different discipline than working with Java. This is worsened by the fact that JavaScript tends to behave differently on different browsers. So in the end, you still end up spending a lot of valuable time having to code for browser differences instead of focusing on real application logic. This is where GWT comes in, providing a real abstraction layer that hides the details of JavaScript and even the differences between specific browser environments.
