I've been developing webapps pretty much since the start of the web in the second half of the 90s, and in Java ever since the first edition of Java EE. During that time, I've met many people and have seen many different approaches to both the development and the testing of the code. One of the funnier parts of web app testing was a testing method used by one of the people I worked with. Between...

Server-Sent Events (SSE) is part of HTML5. SSE is a simple, undirectional communication from server to browser. It allows server to push data to client once a connection is established. The entire point of SSE is to make it easy for the server to push messages to the browser, once the browser has first established a connection to the server. These messages are of the form "field: value" with...

Java User Groups

Recently, there is a heaty debate regarding TDD which started by DHH when he claimed that TDD is dead. This ongoing debate managed to capture the attention of developers world, including us. Some mini debates have happened in our office regarding the right practices to do testing. In this article, I will represent my own view. How many kinds of tests have you seen? From the time I joined industry...

A JBoss User Group (JBUG) is a group of people who share a common interest in JBoss technologies. They are organized and supported by the community and meet on a regular basis to discuss new technologies, development methodologies, interesting use cases, and other technical topics. The common goal is to provide education, help, and social events for the community and to promote open source....

Not too long ago, I actually was planning to attend this year's geecon conference, in Krakow, Poland. But, various events intervened, and I had to cancel. So, I'll have to just pretend it's the third leg of the Java conference hopping trip across Europe that I wish I could have taken this year (the first two stops were Jfokus and JavaLand). geecon's workshops actually happened earlier today;...

In recent years, JavaOne has featured a JCP Panel discussion that features JCP leaders as well as JUG leaders who are actively participating in the JCP, and working toward the JCP.next objectives. Just recently, JCP.Next.4 has launched. This is JSR 364: Broadening JCP Membership. In her recent post, And then there were...

Java Communications

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...

Open JDK

While looking at the bar graph from most recently completed Java.net poll about Java 8 implies a fairly strong consensus, in actuality I think this poll implies that there's quite a lot of disagreement on which aspect(s) of Java 8 are most important for Java/JVM developers going forward. A total of 245 votes were cast in the poll, and two well thought out comments were posted. The exact question...
