Re: GWT vs ExtJs
I would strongly suggest that you stay away from the entire Ext family. They have and continue to have a very deceptive licensing scheme. It's licensed under GPL so you cannot use it commercially unless you are will to open source you client source code *and* your server side source code according to thier very terms of use - which is very bizarre. Secondly even if you do end up buying a commercial license at $329 / license, you still do not have access to the bug fix releases. The $329 / license really doesn't get you much. Version 2.0 final of ExtGWT was pretty much demoware with over 100 critical bugs. 4 - 6 months later several bugs have been fixed but license holders are not entitled to the latest bug fix release of 2.0.3. You not only need a license but you need a support subscription to download the latest stable version. See http://www.extjs.com/products/gxt/download.php http://www.extjs.com/forum/showthread.php?p=393316#post393316 So the real cost of the license is $629 / license / year. In addition to this be prepared to pay frequent upgrade fees for no good reason. Users were required to buy upgrade licenses within less than a year of the ExtGWT 1.0 release because they did an *internal* refactoring to clean up the code and not because new features were added to justify the 2.0 release. A final word of caution - read the terms of their commercial license very carefully and run it by your legal. It's not your typical commercial license that you'd expect with a commercial product. They have some really severe restrictions that might even require you end user / customer to buy a commercial license of ExtGWT.

Re: GWT vs ExtJs
Other reasons for using plain GWT: - no licence issues for commercial apps (but ExtJS has a history of switching licences) - smaller downloads (because user doesn't need to download a js library) - anecdotal evidence suggests it's faster (because GWT can optimize all the js) - the java tools available really do make development more efficient than working in js (type safety, refactoring etc) - support via this group is pretty good, but it seems (from the lack of questions and answers) that most people here only use plain GWT. I'm not sure if third party libs have the same level of support elsewhere. - AFAIK GWT 2.0's code splitting won't work with js libs Paul Дмитрий Николаев wrote: > For my personal experience, I would recommend use native GWT library. > More stable, low cost, good documented, strong typing > > Most of the UI in Ext-js logically replecable by native GWT > > On 19 ноя, 20:11, Palani wrote: > >> We are evaluating GWT and Ext-JS for our application development. >> >> With GWT, I do not need to mess with Java Script and all the >> development can be done in Java. >> >> With Ext-Js, I need to learn JavaScript and it is not strongly typed >> language. >> >> Any other guidance would be appreciated. >> >> Thank you in advance. >> > > -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: GWT vs ExtJs
For my personal experience, I would recommend use native GWT library. More stable, low cost, good documented, strong typing Most of the UI in Ext-js logically replecable by native GWT On 19 ноя, 20:11, Palani wrote: > We are evaluating GWT and Ext-JS for our application development. > > With GWT, I do not need to mess with Java Script and all the > development can be done in Java. > > With Ext-Js, I need to learn JavaScript and it is not strongly typed > language. > > Any other guidance would be appreciated. > > Thank you in advance. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: GWT vs ExtJs
You should also have a good look at Ext-GWT which is offered by the same company. Unlike Ext-JS (which is wrapped JS), Ext-GWT is Java. It's basically a component library layered on top of GWT, but with a (IMHO) nicer and larger set of widgets. To me, the biggest selling point of Ext-GWT (also commonly referred to as GXT) is that it has a very nice MVC architecture built into that allows you to decouple at an even finer granularity than M,V and C. We switched to it from GWT-Ext (essentially pre-wrapped Ext-JS) and have been very very happy and successful with it. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: GWT vs ExtJs
Remember, too, that EXTJS is GPL code so you either have to be pure open source or you need a commercial license. GWT's Apache license is more liberal and allows it to be used in commercial settings. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: GWT vs ExtJs
The Ext-JS component library is richer than what comes with GWT only. Ext Js have done some nice work to get the JS library available in Java trough the GWT-EXT. You can see that on their website. There's also a EXT-GWT project based on Ext-JS, but you'll need the Js open sources library anyway. So it's no like you need to choose betweed them... Ext-JS is not the same thing as GWT... You can have both !

GWT vs ExtJs
We are evaluating GWT and Ext-JS for our application development. With GWT, I do not need to mess with Java Script and all the development can be done in Java. With Ext-Js, I need to learn JavaScript and it is not strongly typed language. Any other guidance would be appreciated.
