Polyglot Programming Is the practice of programming in multiple programming languages. According to Wikipedia it is – In computing, a polyglot is a computer program or script written in a valid form of multiple programming languages, which performs the same operations or output independent of the programming language used to compile or interpret it. In […]Continue reading
This past week I had a real world use case for using Spring Integration Futures. I was looking into optimizing the checkout experience for a large ecommerce website. Consider what happens in a large scale website when an order is submitted. Typically, you will see a process something like: Validate the place order form information […]Continue reading
Object-oriented hierarchy may seem like a simple concept to grasp, since there are so many examples in life to illustrate it. This is not completely wrong. The basic idea behind object-oriented programming is simple. However, the problem is that there are certain details, finesses and tricky situations, that may not be obvious but demand a […]Continue reading
One of the things I wish to do on this blog is to show you realistic examples of using the Spring Framework in Enterprise Application Development. The Spring Framework is very popular for building large scale applications. When you build an e-commerce website that might have 50,000 users on it at any given time the […]Continue reading
Testing software has many meanings, which are often confused. In the last decade or so, we’ve seen agile development methodologies go mainstream in the modern enterprise. These methodologies are often misunderstood and misused. Some times they assume you have clean testable code. Often, when dealing with legacy applications, you simply don’t. I’ve encountered legacy Java […]Continue reading
People expect computer programs to be accurate and precise when calculating numbers, and especially programs that perform monetary calculations and as a Java developer, sooner or later you will need to deal with monetary calculations. You may be tempted to use the primitive types of float or double for non-integer numbers. Both of these types support numbers with decimals. […]Continue reading
Spring Integration Gateways are one of my favorite features of Spring Integration. As a developer, you write an interface for the Spring Integration Gateway, and at runtime Spring Integration will provide you an implementation of the class via the Spring Context for your application to use. What is nice about this approach, the complexities of […]Continue reading
Introduction Spring 3 introduced the Spring Expression Language (SpEL) which has a syntax similar to Unified EL. It can save you a lot of coding, because you can dynamically assign values at runtime. The folks at Spring, made the Spring Expression Language part of what is considered ‘Spring Core’. Thus, the Spring Expression Language is […]Continue reading
While I love Java, this is still pretty accurate! LOL (Its an animated gif, won’t work on FB and some browsers) Java vs C++
Spring Integration is a very powerful module in the Spring Framework. It was originally inspired by pivotal book in computer science called Enterprise Integration Patterns written by Gregor Hohpe and Bobby Woolf. While the Gang of Four focused their work on software design patterns, Enterprise Integration Patterns is focused on how disparate systems communicate with […]Continue reading
