Every March here in the
U.S. we mark Women's
History Month in
recognition of women's
contribution to the
progress of our world.
Technology and the Java
platform are benefiting
as well from women's
talent and dedication and

A couple of years ago I
began developing in Java,
and my first Java project
required that I also
learn SQL. Our project
team was using mostly
EJBs for database access,
although for some
performance-critical
sections of the
applica...
When Nicholas Carr posed
the question 'Does IT
Matter?' in his
now-famous Harvard
Business Review essay, he

would provoke discussion.
He probably didn't know,

Today's web developers
have a lot of choices
when it comes to web
application platforms.
Among them, Java EE has
always stood out as a
'scalable' solution -- it
may not be the easiest
platform to prototype a
web site, but it protect...
Most non-trivial
applications involve high
degrees of concurrency
and many layers of
abstraction. Concurrency
is associated with
resource contention and
an increase in deadlock
conditions. The multiple
layers of abstraction

The creation and
popularity of Web
Services are growing
rapidly in every
industry. With this
continued growth, more

Open Source Business
Intelligence software is
finally coming into its
own, with three major

In concurrent
programming, exclusion
refers to any technique
that dynamically locks
certain blocks of code so
multiple threads can't
corrupt their shared
resources in ways that
can cause integrity
problems. In Java,
exclusion has ...
We have measured
performance information
to distinguish the
differences between the
Windows and Linux
platforms. Given
comparable hardware we
found the performance
differences almost
trivial. When the server

When someone in a
corporate boardroom
decides what their IT
strategy is going to be,
it isn't based on what
language or software
architecture they will
use, but on how a system
can provide value to
their business. Very few

We thought it was time
that the readers of JDJ
