Creating asynchronous servlets with Tomcat 7 (Servlet 3.0 API)
Overall, the API is pretty straightforward to use, assuming that you are familiar with asynchronous processing in the first place. However, if you are not familiar with asynchronous processing, then this business of callbacks can be quite confusing and daunting. Additionally Tomcat 7 and Servlet API 3.0 make it easier to configure servlets using annotations. There are other cool features in 3.0 that I haven’t covered in this tutorial, like loading servlets programmatically. -
Android Location Providers (gps, network, passive)
The best way to handle GPS is to use the “network” or “passive” provider first, and then fallback on “gps”, and depending on the task, switch between providers. This covers all cases, and provides a lowest common denominator service (in the worst case) and great service (in the best case). -
Android Event Dispatch Thread or Main Thread
Android applications run in a native Linux process, in the underlying Linux OS. This process houses activities (screens), widgets, and services (non visual long running application parts). When working with Android apps, it is important to remember to keep long running code running in threads that are not tied to the main thread or event dispatch thread, in order to get an “application not responding” error. A common mistake that is made is long running tasks are performed in this EDT/main thread, and this leads to lots of application failures. -
Using JSON for mobile object exchange
I've been working with various object encoding schemes to get information transferred over the network between services and mobile apps running on Android and BlackBerry. On Android, I figured I would try using Java object serialization, and that works some of the time, and not for anything complex. I wish the object serialization and deserialization mechanism in GWT would be ported over to all these mobile environments, but I digress. This tutorial outlines the use of JSON for this purpose. -
Android Animation Framework Tutorial
This tutorial is an introduction to the built in animation frameworks that are part of the Android UI library. Without writing any animation/drawing code, you can do 2 types of animations - layout transitions that affect ViewGroups, and sequences inside a View.

The basics covered here affect layout transitions, and animation of a View itself, using tweening animation, which includes each of the following effects (or any combination) - Alpha, Rotate, Scale, and Translate. -

How to use the AnimatedTransition API (SwingX and Timingframework)
I needed to perform animations in the app that I'm building for ScreamingToaster desktop app framework using Java and Swing. I needed to build animations that show a transition from one screen to another. This is slightly different than creating custom, or modified components which perform a function and have a set of graphical effects. I needed animations that would transition my user interface from one "screen" to the next. The screens themselves could be panels or components (part of the whole app, or the entire app itself). While I'd been writing much of this code myself, to do these animations, it just got really tedious and frustrating to add this level of complexity to my code, when all I needed were some simple animations. I've been using the SwingX API and the TimingFramework API to perform the animations and leverage the components, however, this last piece was missing. And this last piece just got delivered by Chet Haase, as a part of the binary deliverables with his (and Romain Guy's) great book - Filthy Rich Clients. -
How to use glass pane for animation (SwingX and Timingframework)
I needed to perform animations in the desktop app framework that I'm building for ScreamingToaster. I needed to build animations that move various components around on the screen, and other animations that pop up components on top of existing components, etc. After creating a few of these effects, I realized that I was doing the same thing over and over again, which is why I decided to write this tutorial to encapsulate this pattern, in the hopes that I will help others doing the same thing. -
Creating multi-threaded Swing apps that consume web services
If you've ever want to incorporate web services into your graphical applications / applets / widgets written in Java, then there are some threading issues that you have to be mindful of, and design around. This tutorial will guide you though some of the important threading issues you have to keep in mind when building such applications. The strategies outlined in this tutorial apply to accessing more than just web services from Swing apps; it also applies to loading information from databases, and performing any other kind of time consuming process that has to happen in the desktop app and interact with it, but can't make the user interface unresponsive. -

XML and Java Tutorial, Part 1
In this tutorial, we will create an XML document, the contents of which can be accessed using a JFC/Swing application and from a web browser (via a Servlet). The XML document is a very simplistic representation of an address book which stores the name, email and company name of people. The XML document is written manually, and its structure is known by the Swing application and the Servlet.
