Like Seattle’s latest exotic dancer law, Sun Microsystems has gone “contactless” with its new Java Card platform, which eliminates the need for making contact with a Java Card reader. The contactless smart card can be read up to four inches (10 cm) away, enabling applications in rigorous environments such as public transportation or gaining access to government facilities.
In the hours leading up to the press conference, speculation permeated the tech world over the news Sun Microsystems and Google collaborating on something miraculous.
When you use Java for simple business arithmetic, you may be surprised to discover that Java doesn’t always produce the right answers. If, for example, you use the double data type for an invoice’s subtotal, sales tax, and total, your arithmetic expressions may deliver inaccurate results. I’ll illustrate this in a moment.
IDX Systems has deployed CodeMesh’s JuggerNET to integrate Java and Microsoft .NET applications.

TCO (Total Cost Ownership) is the buzzword in today’s business world. This metric helps enterprise managers assess direct and indirect costs and benefits derived from their investment on IT components and services. A vital component of overall TCO is database management. All information-centric applications need databases for data storage. Also, the storage demands of small and mid-sized companies are growing rapidly, as more emphasis is given on data backup and long-term archival of data disaster recovery.
When application developers are developing, parameters are often hard-coded in the source code. These hard-coded parameters are often pulled out of the source code and put into property files or configuration files. System and network security policies may force a developer to address security concerns over the data that is stored in external files. So, how do you make sure that your sensitive external parameters are safe?
Java filters, first introduced in the Java Servlet specification 2.3, are a powerful addition to any Java Web application toolkit, yet they probably are the most under-used and under-appreciated of the servlet components. These classes intercept requests coming into and responses coming out of the Java servlet container, allowing developers to inspect and manipulate these messages, as well as take other actions based on the messages’ content. Despite this useful functionality, many Java developers are unfamiliar with filters.
The mobile market is envisioned as the next technological wave by leading industry experts. With approximately 150 million mobile phones – roughly 3 times the user base as that of desktop computers – it might well be the case. Due to the fragmented nature of the mobile market, with various manufacturers competing to get their share of the pie, Java is once again poised to be the best programming language for the mobile market with its Write Once, Run Anywhere technology.

The Email List application
This topic introduces you to a simple web application that consists of one HTML page and one JavaServer Page, or JSP. Once you get the general idea of how this application works, you’ll be ready to learn the specific skills that you need for developing JSPs.
Working in Java either means writing a little bit of complex code or writing a lot of gruntwork code. J2EE is a prime example; implementing the persistence for a single database table takes five classes and two interfaces using EJBs, and almost all of the classes are clerical work. We have to write them, but we don’t have to do it by hand. Code-generation techniques can make building high-quality EJB code a breeze.
Hi, I lost all java on my win 98se machine .I’ve done everything short of reinstalling the OS. I reinstalled MS java VM Did not work. So I tried Suns Java, installed it And it still does not work. I uninstalled it then reinstalled it still nothing did this 8 times. I consulted with sun about 4 times, and they told me to do everything I had already done all 8 times i reinstalled it.
The capabilities of the Internet have been enhanced and extended by using programming languages with HTML. These languages have been responsible for the dynamic and interactive nature of the Net. New languages and language extensions are being developed to increase the usability of the Internet. Here I will look at some of the important languages that have shape the Internet over the years.
I have two problems: When I try to start my Ameritrade streamer, the streamer console comes up but the applet menu does not appear. I just get the small square box at the top with the red, blue & green boxes within it. The applet menu does not appear. It was working fine, not sure what happened. It uses Java Web Start. I have tried all their suggestions.
2nd, most of the time, when I go to shut Windows down, it goes to where it says Windows is shutting down and then just stays there. I have Windows 98 and Interenet Explorer 6.0
Question: I am running Win98 and Explorer 6. Recently, I am having a problem with Java. I have not changed any of my setting in IE, but it will not run certain Java pages anymore. I have tried to re-install the latest version of IE 6, but it is still the same. I installed the latest Java plugin, but it is still the same.

Designing maintainable high-performance systems
The new Tomcat 5 server takes filters to a new level of deployment flexibility. Tomcat 5’s support for the upcoming Servlet 2.4 and JSP 2.0 specifications gives filter writers a new way to integrate and deploy these flexible components — tapping directly into the request dispatcher’s operations. In this article, Sing Li takes you on a guided tour of the new enhancement and gives you some hands-on training. See how Tomcat 5 can benefit Web application frameworks and lead ultimately to the design of maintainable high-performance systems.
Web application designers and programmers often face situations where a form submission must be protected against a rupture in the normal control flow sequence. This situation typically occurs when a user clicks more than once on a submit button before the response is sent back or when a client accesses a view by returning to a previously bookmarked page.
MDR-EdO: Welcome to today’s Java Live session on Java Servlet and JavaServer Pages (JSP) technologies. Our guests are computer scientist Marty Hall, and Sun Technical Staff Member Mark Roth. Marty is the author of the books Core Servlets & JavaServer Pages and More Servlets and JavaServer Pages. Mark is the co-lead of the JSP 2.0 specification. This chat was advertised as “new developments in servlet and JSP technologies.” So let’s begin with the basic question — what’s new in these areas?
It’s time to consolidate on what we’ve been discussing in this series about design principles governing the class structure and package structure. In this article, I will present a sample case study in which we will develop a hypothetical application component and try to employ all the design principles we have learned so far, to come up with a reasonable robust design solution.
Apple has just released Java 2 Standard Edition (J2SE) 1.4.1 for Mac OS X. Mac OS X has shipped with J2SE 1.3.1 installed from the beginning. Now J2SE 1.4.1 is available to all Jaguar (Mac OS X version 10.2) owners by using the software update at Apple’s Java product page. Much of the time porting J2SE 1.4.1 to the Mac has been spent moving the GUI elements from the Carbon framework to the Cocoa framework. This means it is easier for your Java applications to take advantage of Mac OS X specific features when running on the platform and to look and feel more like native applications.
Interacting with a database is a routine job in the application world. Quite often you need to store information in the database, fetch it to generate some form of report and update or delete it as required. Java provides the JDBC (Java Database Connectivity) API for executing SQL statements. JDBC, being Java-based, leverages the benefits of the language and provides a convenient way to communicate with different databases, such as Oracle, Informix, Sybase, etc.
Java can be used to create web pages with dynamic and interactive content, to create applications (programs) with Graphical User interfaces (GUIs) and applications that use graphics, animation, audio, and video. With Java, you can also write applications for wireless devices like cell phones and personal digital assistants. In fact, wireless devices can communicate with each other by using Java technology!
Ok, so now you finally admitted to yourself that you’ve got a problem! You have all this code that has been doing its job for years now but it really needs a bit of a makeover. What doesn’t help your cause is that it has come to your boss’s attention that “Java is the way to go!” and he or she is now eager to harness the powers of this mystical thing they call “Java”. This situation may seem a little far-fetched but a lot of developers have found themselves facing the problem of dealing with “legacy code” or code that has been written in a style or language that is now considered outdated.
Thresholding is the process of transforming a set of data that encompasses any range of values to a new set with only two possible values. This process is used often in digital image processing. Thresholding is a form of segmentation, which can be described as grouping pixels together that have like attributes. In most examples of image thresholding, the RGB value (or the Grey Level value for greyscale images) is the attribute of interest.
When considering a benchmark to determine the overall performance of a Java application, bear in mind that bytecode execution, native code execution, and graphics each play a role. Their impact varies depending on the nature of the specific application: what the application does, how much of it is bytecode versus native code, and how much use it makes of graphics. How well a JVM will perform for a given application depends on how the unique mix of these three functional areas maps onto its capabilities. Given these variables, the best way to benchmark a JVM is against your own application. Since thats not possible before the application has been written, you must find those benchmarks that are most relevant to the application you intend to write.
