Java Web Services and XML

Following up on my last entry - this article continues the discussion of WebRPC with a practical example. The example simulates a connected air conditioner that can be controlled remotely via an iOS client app. The server-side Java version of WebRPC is used to implement the simulated air conditioner, and MarkupKit is used to create the user interface for the iOS client. The iOS app uses the...

Around 3 months ago, I have posted one article explaining our approach and consideration to build Cloud Application. From this article, I will gradually share our practical design to solve this challenge. As mentioned before, our final goal is to build a Saas big data analysis application, which will deployed in AWS servers. In order to fulfill this goal, we need to build distributed crawling,...

When I started my career as a Java developer close to 10 years ago, the industry is going through a revolutionary change. Spring framework, which was released in 2003, was quickly gaining ground and became a serious challenger to the bulky J2EE platform. Having gone through the transition time, I quickly found myself in favour of Spring framework instead of J2EE platform, even the earlier...

When I started my career around 10 years ago, Struts MVC is the norm in the market. However, over the years, I observed the Spring MVC slowly gaining popularity. This is not a surprise to me, given the seamless integration of Spring MVC with Spring container and the flexibility and extensibility that it offers. From my journey with Spring so far, I usually saw people making some common mistakes...

Unlock productivity is one of the bigger concerns for any person taking management role. However, people rarely agree on the best approaches to improve performance. Over the years, I have observed different managers using the opposite practices to churn out best performance of the team they are managing. Unfortunately, some works and other don't. To be more accurate, what does not increase...

Recently, we were tasked to develop a SAAS application for big data analysis. To do data mining, the system need to store multi billion public posts in the database and run the classification process on them. Classification in our context is a slow, resource intensive and painful process to assign a topic or sentiment to any record in the database. The process can last up to 24 hours with our...

Java User Groups

When people ask me what am I doing, my immediate response is IT. Even though, the answer is not very specific, it is the easiest to understand and it still helps to describe what we are doing. In fact, it doesn't matter what programming languages we use, our responsibility is to build the information system, which deliver information to end-user. Therefore, we should value information more than...

Recently, I was asked to participate in creating another Java application at my company. It was to be our team's third major Java application since 2002. We felt we had plenty of wisdom from our previous two Java applications to apply to our third one. One of our first steps was to form an application architecture sub-team. This sub-team's purpose was to provide the development team with a solid...

My company uses a large number of software applications to support all aspects of its business. These software applications are either "bought" or "built". The portions of the company that cannot be supported by purchased software are supported by custom developed, in-house, applications. A variety of technologies are used to create and build these custom applications. The Java framework has been...

A while ago, I was asked to evaluate another Java application that was being used at my company. It was a point-of-sale app, developed entirely "in-house" by one of our overseas affiliates. I wondered what their MVC model would look like. How different would their Java app be from the ones I have worked on? I started my evaluation by learning all I could about the architecture and design of this...

Very soon, it will be time for the annual Java One conference in San Francisco, California. Thousands of Java-fanatics will make the journey to my favorite city "by the bay" (and my home town). Thousands more Java-fanatics will not attend (including me) and wish they could. I hope all attendees will have a great and productive time at Java One 2013. My general advice to attendees is, "Make the...
