12336Management application programminghttp://www-106.ibm.com/developerworks/java/library/j-jiro?open&l=766,t=grj,p=FMAjiroIf you're looking for a unique programming challenge, try your hand at building a management application for a distributed, cross-platform network. Consider, for example, what it takes to build a storage network. Network switch and hub technology is typically purchased from one vendor, storage appliances from another vendor, and file servers and software from yet another set of vendors. And then it's up to you to make sure they all work together, with nary a hiccup. Luckily, two technologies have the potential to vastly improve the current state of affairs. This article is the first in a three-part series that looks at how Sun Microsystems's Jiro technology and the Distributed Management Task Force's Web-Based Enterprise Management Initiative (WBEM) can simplify the creation of management applications for heterogeneous environments. Author Paul Monday launches the series this week with a beginner's introduction to the Federated Management Architecture and Jiro technology.Java > Tips and Tutorials > MiscellaneousOct 12, 2006
Here is a short article that may help you while creating a struts project in Eclipse's latest 3.30 i.e Ganymede (I wonder what they will do when all the satellites' names are used
JRuby is an alternate language for the Java platform. It is based on Ruby, a programming language developed by Yukihiro "Matz" Matsumoto. As stated on the RubyCentral homepage (see Resources), Ruby is a programming language that "combines the pure object-oriented power of the classic OO language Smalltalk with the expressiveness and convenience of a scripting language such as Perl." It is a relatively mature language, known for its clean, intuitive syntax and semantics and transparent, developer friendly programming model.
JRuby is a pure Java implementation of the Ruby interpreter. Like most languages discussed in this series, JRuby is both powerful and easy to learn. It incorporates the sophisticated text-processing of Perl, the iterators and closures familiar to Groovy developers, and the rapid development features of Jython and other languages discussed in this series. JRuby is also an interpreted language, so it can be run from the command line or used to evaluate simple expressions or blocks of code on the fly.
For most Java developers, any type of graphics development is intrinsically bound up with the Java 2D and 3D APIs and java.awt.Graphics. While the Java 2D and 3D APIs provide an excellent tool for creating graphics in Swing, they aren't the only ones at your disposal, and they certainly aren't the easiest ones to learn. And for those of you who don't have the time, need, or inclination to burn the midnight oil getting to know java.awt.Graphics intimately, I propose an open-source alternative: JSci
The microdevices that J2ME targets have 16- or 32-bit processors and a minimum total memory footprint of approximately 128 KB. They conform to a Connected Limited Device Configuration (CLDC) while maintaining the Java tradition of anytime, anywhere code portability, deployment flexibility, safe network delivery, and code stability. The prerequisite for the J2ME CLDC is a stripped-down JVM, called the K Virtual Machine (KVM). The KVM is designed for small-memory, resource-constrained, network-connected devices.
Another J2ME configuration, the Connected Device Configuration (CDC), targets advanced consumer electronic and embedded devices such as smart communicators, advanced "smart" pagers, smart personal digital assistants (PDAs), and interactive digital television set-top boxes. Typically, these devices run a 32-bit microprocessor/controller and have more than 2 MB of total memory for the storage of the virtual machine and libraries.
There are a number of different code reviews you can use to enhance the quality of your Java projects. The the primary difference between them is their level of formality. The different code reviews are broken down into three categories, and these are code walkthroughs, code inspection, and code reading. A code walkthrough is the most basic of the three. A code walkthrough occurs when programmers get together to study the codes they've created. A code inspection is the most challenging of the three. It is was first developed in the 1970s, and it follows a process in which each programmer has a specific role
