Introduction to Specification Pattern

Specification pattern has emerged out of “Domain Driven Design” phenomenon. It is first identified and articulated here by Eric Evans and Martin Fowler. Specification Pattern is based on method chaining technique and beautifully uses fluent interfaces. In method chaining, we get desired results by operating over the object through series of methods which returns the same type of object. One of the examples of method chaining is given below,

When to use ThreadLocal?

JDK 1.2 introduced ThreadLocal class to maintain the thread’s local state. A thread may need to share some state with the classes in which it runs and a thread may have its own local state. To maintain such state in the thread-scope, ThreadLocal can be used instead of declaring the state in the Thread class and using synchronization to share it.

Scroller control in JavaFX 2

JavaFX 2.x has many fascinating and useful controls. Among them “TabPane” is also one of the control. Here I am not going in detail about TabPane control, but I would like to inform that there might be some situations where we would like to have a control particularly like the TabPaneHeader ie., adding buttons/nodes dynamically and the scrolling behavior. For example, creating a custom browser layout, adding options scroll in the ribbon bar etc... The basic idea of developing this control is taken from Mozilla tab control.More or less this also includes the behavior of Horizantal ListView. :-)

Caching with periodic updates using EJB 3.1 Singleton and Timer

With the introduction of Singleton beans in EJB 3.1, implementing a cache in the business-tier has become easy. Only one instance of a singleton bean is created per JVM (in case the application server runs in multiple clusters) by the EJB container. The singleton beans also provide other features of EJB – transaction and concurrency management, security, remote access, life cycle callbacks, interceptors and dependency injection.

Behaviour Oriented Modelling

According to laws of classical physics, the future state of a system can be determined solely from its present state. This means that behaviour of a system is the outcome of its state or structure. This is fundamental assumption underlying most engineering disciplines.

Seven Value Medals a day!

We all spend about 250 days a year at work and do we really get the maximum out of those days for ourselves, our clients and the company? Of course we all strive to do our best, despite that many a time we are left with a feeling that we did not reach our maximum potential for contribution. Is there a simple way we can plan and manage our day to maximize our contribution, results and eventually rewards?

Choreography and Orchestration: A Software Perspective

While thinking about the complexity resulting from conventional object oriented techniques in building enterprise software, I realised that such complexity is in the nature of such OO-like systems as they grow really large.
