Java User Groups
Assembling a team of Java developers can be a challenging task.
Getting the right people together requires a combination of luck, skill, and plenty of patience.
When someone new joins your team, they could also be new to your company.
Over the years, we have conducted many job interviews of Java developer candidates wishing to join our team and company.
Our Java job interview format is simple and...

Our team of Java developers consists of people with various backgrounds and skill levels.
Everyone has a role and is assigned tasks based on that role.
Team members are expected to know basic programming concepts, core Java and core J2EE.
In addition; database access, web-browser, client/server concepts are required as well.
It didn't take long for our team to realize there was a lot more to know...

I am back with more stories about our adventures in the world of Java.
From the distant past to recent events. I hope to entertain, enlighten, and encourage.
So hold on to your hats.
For software developers in IT, there are times when you find yourself present at the birth of a major application.
Normally these are dream assignments. But consider the following additional factors.

Spatial reference system: What is it?
by Regina O. Obe and Leo S. Hsu, authors of PostGIS in Action, Second Edition
The topic of spatial reference systems (SRS) is one of the more abstruse in GIS to understand. This is mainly due to the loose way in which people use the term spatial reference system and secondly to its unglamorous nature compared to other areas of GIS. If GIS is Disneyland,...

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

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...

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.

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.

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...

Acceptance Test Driven Development (ATDD) is a very effective development practice that essentially involves writing specifications in the form of documented and automated examples. These automated examples become automated acceptance tests that validate the features being delivered. The process of writing these examples encourages teams to focus on where the business value of a feature is coming...
