Java User Groups

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...

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....

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...

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...

During the initial architecture and analysis of our J2EE-based application, one Java issue generated a lot of attention on our team : Enterprise Java Beans or EJBs. Should we use EJBs? What flavor of EJBs should we use? At the time, we received no practical advice on EJB usage. We got a lot of general advice. "Use what is best for you, etc." Quite often, we were referred to a diagram with a lot...

In the beginning, our development team had no Java experience at all. Most of us were mainframe developers with a decade or so of IT experience. We realized that not only did we need Java training, but we needed training on object-oriented concepts as well. It seemed like a very challenging goal to achieve. One of the reasons we chose our particular Java software tools vendor is because their...

10 years ago, when we were decided to use Java technology to create a new application, for use at Amway Corp; we thought it was sufficient to say, "We are using Java!". We were wrong... We quickly realized that there was Java 2 Standard Edition and there was Java 2 Enterprise Edition. Since we were architecting our application to run in an application server-based environment, we concluded that...

Knuth-Morris-Pratt (KMP) Overview According to Wikipedia, the Knuth-Morris-Pratt algorithm "searches for occurrences of a "word" W within a main "text string" S by employing the observation that when a mismatch occurs, the word itself embodies sufficient information to determine where the next match could begin, thus bypassing re-examination of previously matched characters". Being 'A' the...

Hello all. My name is Larry Fernandez and I am a Principal Software Developer in IT. I work for Amway Corp in Grand Rapids, Michigan. March 2012 was my company's 10-year anniversary using Java. We have over 1 million lines of J2EE code in production, with more on the way. I have been here since our "Java" beginnings and I have played many roles (developer, architect, project manager, etc.). We...

String searching algorithm (SSA) According to Wikipedia, string searching algorithms are "an important class of string algorithms that try to find a place where one or several strings (also called patterns) are found within a larger string or text". Some important concepts that you need to understand before reading this entry are pattern, string and alphabet: Pattern: Set of elements that...

Java Tools

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...

Java Patterns

When we starting planning how we were going to use Java technology at Amway (10 years ago); we realized we had many decisions to make about standards to adopt, practices to learn, architectures to use, patterns to follow, etc. Fortunately for us, there were many sources of information to help us figure all of this out. Unfortunately for us, there were many sources of information to help us figure...

Java Desktop

Boyer-Moore (BM) Overview According to Wikipedia, the Boyer-Moore algorithm "is an efficient string searching algorithm that is the standard benchmark for practical string search literature. It was developed by Robert S. Boyer and J Strother Moore in 1977. The algorithm preprocesses the string being searched for (the pattern), but not the string being searched in (the text). It is thus well-...

Global Education and Learning

Hello there! I'm Alessandro Gentile and this is my brand new blog on java.net. I must say, I'm honored to be part of this community. Two months ago I joined the GlassFish project and I began to write tutorials. There are several reasons for my choice and among them there's the love for open source software and java EE. Markus Eisele in his blog two weeks ago wrote an article that I found truly...
