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...

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-...

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....

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...
