I'm at OSCON in Portland, Oregon this week. I will be posting my notes here.

As we began our Java adventure at Amway Corp 10 years ago, one of the most important tasks we had to do was to create our Object Model. We had a variety of Java objects that we were planning to use in our application. How were they going to be "wired" together inside of the application? After 4 weeks of Object-Oriented, J2SE, J2EE training; we set out to define our Object Model. This model was...

As we began to learn about Java technologies at Amway Corp, we were introduced to UML (Unified Modeling Language). We became interested in the modeling aspect of UML to assist in the analysis and design phases of our Java project. So we decided to try our hand at modeling with UML. It began with 2 week-long training classes. 1) Object-Oriented Analysis with UML 2) Object-Oriented Design with UML...

In order to successfully migrate our mainframe application to a Java/application server based solution, we had to figure out how to migrate our batch processes. We had a very good start, in achieving this, by utilizing the LaunchClient command and J2EE Client programs. It was just a matter of putting the remaining pieces together into a working solution. But we were running into a lot of trouble...

Our first Java application (10 years ago) was a migration of a legacy application. The legacy application consisted of a number of screens and a number of batch processes. Migrating the screens to Java technology seemed straight forward. In theory, they would be a direct use of the MVC pattern (EJB, JSP, Servlet). Easy. But what about the batch processes? They didn't seem to fit the MVC pattern....

Martijn Verburg, of the London Java Community, announced on the Java.net JUG-Leaders mailing list that the Adopt OpenJDK program is seeking Java User Groups for a new Adopt OpenJDK Bugathon pilot training program. Martijn said: "We're looking for 3 JUGs to be part of the pilot for expanding the Adopt OpenJDK bugathons (hack days) to a global audience!" If you're not familiar with Adopt...

Our Java application supports my company's (Amway Corp) Customer and Sales Compensation areas. This is a very unique and complex part the Amway's business model. The application requires a large database to store business-related data. The database consists of dozens of tables and millions of rows. It contains transactional data and summarized data. The size of the database grows daily. Database...

After reading the JCP.next.3 - JSR 358, i can see the prospect of Harmony become JavaSE. Yes, there is no reason to keep block the Harmony become JavaSE.. to keep the community under Java umbrella, we need to make it.. but i can see Java will move from product become standard.. the RI is ok.... but i love the new body.. :) will JSR 358 make this happen. I believe this is amazing challanging,...

As our Java project progressed, we began to add new members to our development team. This meant many resumes to review and many interviews to conduct. It was to become quite a time consuming chore for the interviewers. During a portion of the interview, a series of technical questions about Java are asked. The goal behind these questions is to allow the interviewee to talk to us about Java. Some...

Java Desktop

Our recently completed poll about the Adopt OpenJDK project suggests that the project is gaining some visibility among Java developers, but there's a large group that isn't all that familiar with the project. A total of 428 votes were cast. The exact question and results were: What's your view of the Adopt OpenJDK project? 17% (74 votes) - It's a great idea - I plan to participate 7% (29...

Java Tools

The VisualLangLab API documentation now includes a Clojure companion for the existing Java client example. Unlike other parser-generators, VisualLangLab does not generate any code. Instead, it turns its visually depicted rules (or grammar-trees, see figure below) directly into a parser instance at run-time. These parsers are accessible via the API from programs in any JVM language....

For us at Amway Corp, a key part of creating batch processes, with Java, was using the LaunchClient command and J2EE Client applications. We felt we were very close to being able to run our Java batch processes on the application server. But more trials and tribulations were ahead of us. We created a J2EE Client application\program that would call a "hello world" EJB. After deploying the code to...

Earlier versions of VisualLangLab required the user to specify an alphanumeric name for all tokens. This made it difficult to understand rules using tokens without intuitive names. A good example is the rule infixOp from a Java grammar in Figure-1 below. Figure-1. Rule with non-intuitive token names While PLUS and MINUS have good mnemonic value, many users will not understand TILDE and BANG. And...

JCP

The first JCP Executive Committee public meeting of 2012 took place on Tuesday, June 26. The meeting was open to any Java developer who wanted to attend, via Oracle's international phone network and the JCP's Webex account. I called in. I also tried the Webex option, but couldn't fully connect (I think due to my own system, which isn't yet fully operable after a recent disk crash). Most of the...

Java Patterns

If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle. Sun Tzu, Chinese general. The Art of War INTRODUCTION Ladies and Gentlemen, Like you, I'm intimately convinced that a professional...
