ExtJs Vs Ext GWT Vs SmartGWT

I am going to start a new application which mainly consist NavigationPane, Grid, Toolbar. Layout should look like this demo page http://www.gwt-ext.com/demo/

I am quite confused which one to use in terms of writing less code, more performant, etc.. Could someone tell the pros and cons of all these technologies.

All the while I coded in javascript, so that way ExtJs seems to be the easy one for me to code. But I am curios to try GWT Ext, Is it true that it could do a lot just by writing few lines of java code.

For eg: To achieve the layout ( given in above gwt ext demo url), which one should I opt ExtJs or GWT Ext.

I read SmartGWT is relatively slower than GwtEXT. Does it have any advantage over GWT EXT. I am also looking for hibernate based data modules ( as my application is going to have many database calls). Anyone of SmartGWT or GWTExt has support for such modules. I came to know that smartgwt doesn't offer all of smartclient enterprise version functionalities, that we are allowed only a few of smartclient features. Will it be an issue?

Your response is highly appreciated.

Solution

  • To write the least code, use SmartGWT Pro. It provides a wizard that allows you to just pick from a list of Hibernate entities you've created, and instantly you have the ability to perform all CRUD operations on that entity, no code required. Then you can add business logic.

    The wizard:

    http://www.smartclient.com/smartgwtee/showcase/#tools_hibernate_wizard

    The link about is just screenshots, but there are several Hibernate samples in the showcase. See especially the Master-Detail Batch Load and Save sample.

    As far as performance, real-world performance of most enterprise apps is dictated by how often the application has to contact the server. In this area SmartGWT has a large lead because of features like Adaptive Filtering (see the Featured area in the SmartGWT showcase).

    Almost all reports we receive of SmartGWT being "slow" are due to having Firebug enabled. Disable Firebug and performance is fine, so normal end users will never perceive slowness.
