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...

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...

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...

VisualLangLab now has a Java7 (JDK7) grammar! Read on to find out how you can use the grammar to locate usages of the new Java7 (project coin) language features in the source-code of the Oracle JDK 7u3 itself.
If you are new to VisualLangLab (an easy-to-learn-and-use parser-generator) condsider reading the tutorial A Quick Tour.

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-...

Running the new version of the Easy-Cassandra framework it main objective is making it easy the communication between Apache Cassandra and your application in java. With it you able create, update, retrieve, delete the java's objects in easy way and simple, for this you must add some annotation in Class and fields.
An ORM easy to use in Cassandra...

Easy-Cassandra is a framework ORM API and a high client for Apache Cassandra in java, with this is possible persist information from the Java Object in easy way. For this is only necessary add some annotations in some fields and your class. It works like an abstraction's tier in the Thrift, doing call for Cassandra.

Welcome to the 198th issue of The Java(tm) Specialists' Newsletter sent to you from Chania in Greece. My readers in colder climates frequently get annoyed when I tell them that "life's a beach". They imagine us having constant sun here. It's not true. We do sometimes have torrential rains and cold weather. It even snows here occasionally. In fact, the delivery...

Nowadays the Enterprise applications beyond persist String and number also can save file. 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...
