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... (more)
This article is a transcript from a recorded conversation Yakov Fain had with
Anatole Tartakovsky and Victor Rasputnis – his business partners at Farata
Systems. This conversation took place on the mountain after the day of
skiing.
Yakov. There are many ways of creating Web applications and creating them for
the enterprises is not the same as developing a Web site for a pizzeria in
your neighborhood. During the last five years we’ve been using mainly Adobe
Flex for development of the front end of Web applications. Flex applications
work in a well known and predictable run-time e... (more)
OK, our company, Farata Systems has created this nice application using Adobe
AIR, and our customers are happy. It’s not a simple CRUD though. We’ve
implemented some cool stuff replacing tons of paper forms with PDF documents
processing. PDF documents are being scanned, the OCR software processes them
to automatically figure out what type of document is it to properly save it
in a database. Customers’ checks are scanned, digital signatures are
flying, reports are being created… All is integrated into one Adobe AIR
application. No external Acrobat Reader, no nothing. I’m not sayin... (more)
During the last month my colleagues and I were immersing into the world of
modern JavaScript frameworks. We didn’t start from scratch though. My
business partners spent the first 5 years of this century porting
PowerBuilder, a used-to-be-popular client server tool, to a JavaScript
framework. That product was called XMLSP and you can still find its 5-year
old version online. The word AJAX was not even invented back then. In 2006, a
killer UI framework Adobe Flex 2 was released and we started using it. It was
clearly better than any AJAX offering, and I was not shy in publishing bl... (more)
This is a book excerpt from the book RIch Internet applications with Adobe
Flex and Java.
Configuring the Server-Side Destination and Proxy
For security reasons (similar to the Java sandbox concept), Flash clients can
only access the domains they come from, unless other servers declare,
explicitly or implicitly, trust to SWF files downloaded from our domain by a
corresponding record in a crossdomain.xml file. But our portfolio SWF wasn't
loaded from finance.yahoo.com, and we aren't allowed to install
crossdomain.xml on the Yahoo! servers. We'll use another technique called
Flex p... (more)
