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...

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...

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...

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...

Persist this information is very interesting, for example, a civil process there are information about the process (name of author, date, number of protocol) and the document which represents, or a twett with an image. In Apache Cassandra, you can save file, but for large file you should use...

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-...

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...

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...
