Just yesterday I posted about “thinking” to create the Java API to work for Dojo on GWT. And today, it’s kind of official.

Edujini Labs is going to sponsor this project. Check the posting on Eduzine here.

In fact, a mail to the Dojo Team has already been sent about the intimation of the same.

Have a look at the “Hello, World!” on the early-stage DWT.

My real love for GWT started only a couple of days ago… and it prompted me to get started with Dojo on GWT.

I have, so far, written a couple of core-classes in Java mainly to abstract out the interaction with JavaScriptObject.

My next target was to directly jump on to dijit, and start creating the UI. And then I realized that it uses mixins. And now I am left wondering what’s the best way to handle mixins.

For the new comers, JavaScript allows single inheritance but Dojo (and other libraries) make use of mixins to pseudo-inherit methods and properties from other objects by copying them to the sub-object.

In Java, this can be achieved only by making use of interfaces. The other possibility is to introduce a class between the parent and the child class that encapsulates the mixin objects.

I think the latter is a better approach. Simply expose the object or may be create delegate methods.

Let me think over it… what’s the best way to marry Java and JavaScript.

I had been working with WIA (for Windows XP) and WIA 2.0 (for Windows Vista) to design an application to capture images.

WIA for Windows XP works perfectly fine. And WIA 2.0 is supposed to do the same on Vista.

And then, I hit a hurdle - WIA 2.0 always gives me “0 devices” while using EnumDevices method. Finally, I hit yet another set of documents - Windows Portable Devices (WPD) here.

What the heck! Do I need to rewrite the entire application for Windows Vista? What does Microsoft want? Spend all time and money only to rewrite entire code every time a new version is released from their side?

At times, I really hate to develop any application on Windows.

The only good thing, at least at moment as it seems, is .Net Framework. At least, there I need to do minimal work. I wish it was the same case elsewhere also.

Without any introduction, let me just list down some intersting events of the day…

Reached the entry gate of the company premises only to find that the contact person is on leave.

The contact person did not delegate his responsibilities, if at all any, to somebody else.

Upon reaching the training room, there was not a single computer for the audience to lay hands on for the case studies. Hey, you know that it’s an IT Training.

As I mentioned in one of my earlier postings that I had to do study of some internal stuff in Team Foundation Server - mainly related to Custom Check-in Policies, Custom Work Item UI Controls, Custom Alerts and Notifications (Events) etc.

I reached the client’s office (office gate to be precise) at around 8:25am. The company premises has about a dozen entrances because of the sheer size of the campus.

After going around a couple of gates, found the correct gate. As what the professionalism says, the security was informed about our (my colleague and mine, who else) arrival. So, no problems in getting the visitor pass.
