Lightweight application frameworks are all the rage in the enterprise Java
community in the past couple of years. From the pioneering Spring and
Hibernate frameworks, to the infusion of technologies like aspect-oriented
programming and metadata annotation, to the new standard EJB 3.0 (and Java EE
5.0) specifications, lightweight frameworks have gradually become mainstream.
The rise of lightweight technologies was largely due to developers' rebellion
against the "heavyweight" of EJB 2.1 (and earlier). Lightweight frameworks
aim to make developers more productive and the application less error-prone
by removing the rigid EJB 2.1 infrastructure classes/interfaces and excessive
XML deployment descriptors (commonly known as "XML hell" in EJB 2.1). Beyond
that, lightweight fr... (more)
"Java on mobile phones" has been the hottest topic at the JavaOne conference
for the past several years. This year was no exception and a large part of
the show floor was designated as the "Wireless Village." With tens of
billions dollars' worth of Java phones and related services sold every year,
Sun and many others are clearly making money. However, most JavaOne attendees
I met were en... (more)
Is Ruby Replacing Java? – Not So Fast
Okay, I have heard it all: Ruby On Rails (RoR) is so much cooler and simpler
than Java EE. It allows you to write web applications 10X faster. And Ruby
has nifty language features we can only dream of in Java. So, Ruby must be
replacing Java to become the "next" programming language just as Java
"replaced" C++/COBOL and C++ "replaced" Fortran.

Annotation is a new Java language feature introduced in JDK 5.0. It has
quickly become one of the most popular, and yet most controversial, language
feature in core Java. New Java frameworks, such as EJB 3.0 and Hibernate 3.0,
make extensive use of annotations to eliminate the excessive XML
configuration files (a.k.a. the "XML hell" in Java EE). Those annotations
significantly reduce the... (more)
