Gwt-Ext screencasts for beginners

Tag: Ext, Gwt, Java, Javascript, Links, Programming, Ubuntu, Web — Abhijeet Maharana @ 8:51 pm

I have started out with Gwt-Ext and thought I will record some screencasts. These are for beginners who may need a hand when they are starting out and are anxious to jump right into code. The screencasts have been recorded on Ubuntu Feisty with Eclipse Europa.

There are 3 screencasts in avi and ogg format.

  1. First screencast shows the installation of Gwt 1.4 and Cypal Studio for Gwt. Cypal Studio is an Eclipse plugin that automates most of the tasks associated with GWT like adding a module and adding a remote service. In the screencast, I create a Gwt project using this plugin.
  2. Second screencast shows how to add the ExtJS Javascript library (2.0) and Gwt-Ext Java library (2.0.1) to the project. In the screencast, I create a simple Ext form with some text fields and a button.
  3. Third screencast (added on March 22) shows how to send form data back to the server. In the screencast, I validate form fields using regular expressions / Ext Vtype, add a remote service and then save form data in an Oracle database using the remote service.

    You can read this post for installing Oracle 10g XE on Ubuntu Feisty.

All screencasts are hosted at Rapidshare. Sanjiv Jivan, the author of Gwt-Ext has offered to host them at gwt-ext.com. I think the files are quite big and I am not well-versed with audio/video formats and parameters. If you know any way to reduce file size while maintaining the quality of screencasts, do let me know.

Update:
Sanjiv has been kind to host them at http://www.gwt-ext.com/screencasts/.
I have also edited the gwt-ext wiki accordingly. (See comments)

    Hi, thanks a lot for these very helpful screencasts!

    Especially the third-one which allowed me to understand how to store data in a simple way.

    Best Regards.

    I’m curious as to what the avi’s are encoded with. QuickTime on a new 10.5.2 mac is bitching about not having the right codec installed, while not telling me which codec it doesn’t have…

    Hi Brett,
    They are encoded with FFmpeg MPEG-4. Vlcplayer runs them just fine (I have Ubuntu 7.04 with vlcplayer and codec packages installed from the repository).

    Also, the Eclipse projects I created while recording the screencasts are available at http://rapidshare.com/files/105768477/EclipseProjects_WorkingWithGwtExt.zip
