JavaOne

Mattias Karlsson (@matkar) is a Java Champion, JUG leader, speaker, consultant, software vagabond, and founder of the Jfokus Conference (@Jfokus, which will take place February 4-6 in Stockholm, Sweden). At JavaOne 2012, I had an opportunity to chat with Mattias about Jfokus, Java User Groups, and the state of Java in Sweden. My first question was something I've actually wondered about for...

Much of my Tuesday at JavaOne 2012 was spent thinking about questions to ask the people I was going to interview, conducting the interviews, and trying to set up interviews for Wednesday. Late in the afternoon I attended the 2012 Duke's Choice Award Winners JavaOne BOF session, followed by the Duke's Choice Award Winners dinner. Today I interviewed: Mattias Karlsson, Java Champion, Stockholm...

Searching at Scale by Trey Grainger and Timothy Potter, authors of Solr in Action One of the most appealing aspects of Solr, beyond its speed, relevancy, and powerful text searching features, is how well it scales. In this article, based on chapter 3 of Solr in Action, the authors explain how Solr is able to scale to handle billions of documents while still maintaining lightning-fast search...

Oracle just give free ADF Essential on Glassfish, a streamline edition of ADF. An interesting thing is there are also OEPE (Oracle Eclipse Plugins) that have ADF inside. which the Jdeveloper edition is far more complete and rich. www.oracle.com/technetwork/developer-tools/adf ADF Essential is free for glassfish deployment, and with support US$ 1250/server (/core??), and you will get the source....

10 years ago, we began our journey into the world of Java and "J2EE". It was a big risk for my company, Amway Corp, to do this. We had no in-house expertise and we had critical applications to migrate to the new technology. From the beginning, we were determined to succeed. Today, 10 years after; I can say our Java adventure has been very successful. We have created two complex applications and...

A few years ago, we met with our business analysts to discuss security for our application. Our goal was to implement our own authentication mechanism for the web-based or user-interface portion of the application. We defined authentication security as "access rights to resources of the application". After some initial discussion, one of our business analysts suggested we look for an industry...

When my company, Amway Corp, makes a sale; somewhere, somehow a computerized transaction of that sale is created. This transaction is sent to a number of applications at Amway for processing. One such destination is our Java application. We created a capability, called the Transaction Monitor (or TM) to deliver transactions to our app. Our initial version of the TM worked well, but it was still...

During our 10 years of using Java at Amway Corp., some of our solutions required us to think a little "outside of the box". Our application had a reporting requirement. It had to generate reports from the application's various batch processes as they were running. These batch processes performed transaction processing, data purging and data exporting functions. The reports would not be used by...

It never ceases to amaze me where some solutions in application development come from. We had a requirement for our application to allow a user to print pages of text. The user would bring up a web page, from our app, and then create & print a list of customer names. The list of names would be created by executing a SQL query against the database, using a variety of search criteria. The users...

by Dan McCreary and Ann Kelly, Authors of Making Sense of NoSQL Bigtable systems are important NoSQL data architecture patterns because they can quickly scale to manage large data volumes. They are also known to be closely tied with many MapReduce systems. In this article from Making Sense of NoSQL, the authors discuss how Bigtable systems store data using row and column keys and how they...

Accessibility

We began creating our second Java application five years after we began the first app. We were hoping the second application would give us a chance to use additional Java technologies. We began by gathering all of the known functional requirements and matched them to the various Java-related technologies we knew of. The result was a high-level technical architecture of the application. This...
