Adobe AIR + extjs for desktop application

For building desktop application, there have .Net and Java Swing solution. However, there seems not that elegant for me. Recently we are trying to use following structure to build own desktop application:

Adobe AIR (SQLite buildin) + extjs

This is the general steps we process to build extjs + AIR project:

1: Download develop tool which will use to edit/package adobe air project (Adobe air and Aptana studio)

http://www.adobe.com/devnet/air/ajax/getting_started.html

2: Start Aptana and install plugin

Click the icon (4th or 5th icon in second line): "Open Plugin View", you will find:

• Adobe Air support
• extjs support

Install those 2 plugin.

3: Now start Aptana - create new project

File -> New -> project -> Adobe Air Project

You can create some example project - such as: Tasks. And you will find 2 important files: tasks.html and application.xml

4: Hit: Run -> Run ...

You will see your example running ...

5: Export/deploy air project.

You need setup certificate. Every AIR application requires certificate signing in order to be built and deployed.See this link for more information:

Some problem ...

* If you see "invocation forwarded to primary instance"

You need go to your task manager and kill manually ADL.EXE
