With the official release of Java EE 6 in December 2009 a new version of the Enterprise JavaBeans specification also saw the light. Enterprise JavaBeans is an architecture for the development and deployment of component-based business applications. Applications written using the Enterprise JavaBeans architecture are scalable, transactional, and concurrent.
While a lot of faithful EJB developer's have been scared away from the specification and some of its unfortunate implementations in the past five years, EJB 3.1 has all the ingredients that make for a successful lightweight component based implementation. At last a decent implementation of a server-side component framework as part of the Java EE specification. This no longer makes you dependent on rebel frameworks such as the Spring framework.
EJB 3.1 continues down the path where EJB 3.0 left us off. The purpose of the Enterprise JavaBeans 3.1 specification is to further simplify the EJB architecture by reducing its complexity from the developer's point of view, while also adding new functionality in response to the needs of the community. Although the Java Persistence API was developed within EJB 3.0, it now evolves under a separate JSR rather than within EJB 3.1 and will therefore not be covered in this presentation.
This presentation will mainly focus on the new features introduced by EJB 3.1 and the basics of EJB are only covered very briefly. Topics covered include: EJB Lite, simple packaging, no-interface local view, portable JNDI names, Embeddable API, Startup/shutdown callbacks, Singleton beans, the new and improved timer and scheduler component, Async invocations, and REST integration.

In this session, we'll show you how CoreMedia's Maven plugin offers the deepest integration of Sencha Cmd into your Maven build process available today and takes modular Ext JS development to the next level.
There are cases when product has a lot of business logic and want's to share it across web and mobile platforms, especially when the web part uses React and mobile - React Native. Sharable code adds development speed, simplified communication between teams, removes behaviour differences between web and mobile. At the same time there are a lot of things which can increase a solution complexity and add some limits to the final product.
This is a talk I gave recently to the department of Computer Science at University of Illinois at Chicago on Apache Maven. Hope it's useful.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Simple and Boolean properties
// member used to store property value //
private String internalString;
// set and get method for property named String //
public void setString(String newValue)
{ internalString = newValue; }
public String getString()
{ return internalString; }
// member used to store property value //
private boolean connect;
// set and get method for boolean property name connected //
public void setConnected(boolean newValue)
{ connect = newValue; }
public boolean isConnected(} { return connect; }

Indexed properties
• An indexed property represent a
array of values. And we can use
additional get and set methods for an
indexed property. This get and set
method take an integer index
parameter. This index parameter
indicates the place in the array where
the new property value has to be put.

Manifest Files
– To indicate which of the components in a JAR
file are Java Beans
– Example
• d:/demo/one.gif
• d:/demo/two.gif
• d:/demo/three.gif
• d:/demo/one.class
Java- Bean:True
– A manifest file may reference several .class
files. If a .class file is a Java Bean, its entry
must be immediately followed by the line
“Java- Bean:True”.
