Serve clients' specific protocol requirements with Brazil, Part 6
In this conclusion to his series on Brazil, Rinaldo Di Giorgio
demonstrates how to use the following technologies with the Brazil
toolkit: Jini, BeanShell, and the Java API for XML Messaging
(JAXM). You can also use Brazil with many...
Serve clients' specific protocol requirements with Brazil, Part 4
This fourth installment of Rinaldo Di Giorgio's Brazil technology
series introduces you to multicast via JRMS (Java Reliable
Multicast Service). Multicast is a protocol that supports
simultaneous message transmission to multiple...
Serve clients' specific protocol requirements with Brazil, Part 3
In Part 3 of the Java Developer Brazil technology
series, Rinaldo Di Giorgio shows how the Brazil server transmits
weather data to wireless clients. Using three different wireless
access environments -- Palm, Openwave (previously,...
Serve clients' specific protocol requirements with Brazil, Part 2
In this second article in the Brazil technology series, Rinaldo Di
Giorgio will demonstrate how to use XML to facilitate data exchange
between applications. Specifically, he'll explain how you apply XML
to exchange weather data. He'll...
Serve clients' specific protocol requirements with Brazil, Part 1
In his last column, Rinaldo Di Giorgio discussed how to support X10
devices through a Brazil handler. This time, he begins a series
that will utilize the Brazil Web server as an experimental
application server. The Brazil sever can...
How handlers work in Web-accessible home automation
The Brazil server project at Sun Labs began as an HTTP stack with
an extremely small footprint. It was originally designed to provide
a URL-based interface for smart cards, so that smart cards could be
accessed easily from an ordinary...
Use software components to deploy applications with Java Cards
This article provides a broad overview of how OpenCard and the
smart card URL Programming Interface (UPI) -- both of which have
been discussed in prior JavaWorld articles -- can be used
to design an application, load it onto the...
Learn to use software components to deploy applications using Java Cards
This article will provide a broad overview of how OpenCard, and the
smart card UPI URL Programming Interface -- both of which have been
discussed in prior JavaWorld articles -- can be utilized
to design an application, load it onto...
An introduction to the URL programming interface
The demand is increasing for universally available networks and
devices for personal and corporate use. For example, wouldn't it be
useful to be able to get a file from your home system in Australia
while you were on a business trip...
An instrumentation network for weather data on the Web
This article is the first in a series of articles that will examine
how Java can be used to improve and reduce the cost of collecting
realtime data on the Web. Over the next few months, several
architectures, including HTTP posting,...
Write OpenCard services for downloading Java Card apps
Loading Java Cards can be a confusing process requiring proprietary
development tools that work on only one platform. Sun Microsystems
is developing a standard in this area for Java Card licensees. But
what do you do in the interim:...
How to write a CardTerminal class for simple and complex readers in an OpenCard environment
In October, the 1.1 release of the OpenCard Framework was
announced. There were a number of changes to the previous release,
version 1.0, in the area of card terminals. These changes greatly
simplify programming of card terminals and...
How to write OpenCard card services for Java Card applets
OpenCard provides an API that allows different card readers,
different platforms, and different Java Cards (as well as non-Java
Cards) to be used by the same Java code with no change. With
OpenCard you can run Java smart card...
Java gets serial support with the new javax.comm package
One of the most popular interfaces on a PC is the serial port. This
interface allows computers to perform input and output with
peripheral devices. Serial interfaces exist for devices such as
modems, printers, bar code scanners, smart...
An introduction to the Java Ring
The Java Card is being implemented on many form factors. The Java
iButton from Dallas Semiconductor is one of the first devices
claiming support for the Java Card 2.0 API. (Compliance testing has
not been done yet.) Java Card isn't...
Understanding Java Card 2.0
Java Card is a smart card that is capable of running programs
written in Java. For this new Java platform, Sun's JavaSoft
division has made available the Java Card 2.0 API specification,
and several licensees are now implementing this...
Get a jumpstart on the Java Card
This article describes how to get started programming a smart card
that supports Java. The examples are based on the Schlumberger
Cyberflex Java Card family, the first production Java Card, based
on the Java Card 1.0 API licensed from...
Smart cards and the OpenCard Framework
The OpenCard Framework provides programmers with an interface for
the development of smart card applications in Java. Implementations
of OpenCard can be 100% pure Java, or they can use existing card
terminal implementations (a.k.a....
Smart cards: A primer
This article, the first in a new Java Developer
series on smart cards, will introduce you to smart card hows and
whys. All you need is a smart card, a card reader, and software
that lets you communicate with the card, and you can...
Use native methods to expand the Java environment
Using Java, it is impossible to build applications that access
libraries and applications in other languages; that is, unless you
are willing to use the underlying operating system (OS). This is
not a failure of Java, but simply a...
