Clear Data Builder for Ext JS (CDBExt) is an open source tool that automatically builds Ext JS/Java EE CRUD applications given one or more annotated Java interfaces. The generated JavaScript and Java code enforce best Ext JS and Java EE practices and is deployed on the development version of the Tomcat ready to run. A tiny library of Ext JS components accompanying CDBExt – Clear components – enables transactional data sync with the application server, including deeply nested hierarchical data transaction, features not supported in native Ext JS 4.

This short video opens a series of demos that will describe various modes of generating CRUD applications with the JavaScript clients enriched by the Ext JS framework from Sencha. At the time of this writing, CDBExt is in public beta and your suggestions are welcome. Please post your suggestions and findings at the Clear Data Builder’s forum at Sourceforge. You can also send us your feedback by filling out this form at our company’s site.

We’ve just started documenting CDBExt at the Clear Toolkit’s Wiki.

In the next video I’ll show you how to quickly create a Web application using the Ext JS framework as a client and MyBatis framework for the data persistence. If you are not familiar with the HTML5 framework Ext JS, consider attending our 2-day workshop on the subject.
