Mastering J2EE can be daunting, with an ever-growing list of technologies and acronyms. The Java Naming and Directory Interface (JNDI) has been at the core of the Java 2 Platform, Enterprise Edition (J2EE) from its inception, but it is often underutilized by novice J2EE developers. This article will help demystify the role of JNDI in J2EE applications and show how it can help decouple your application from the details of deployment.
A Business Configuration Set is a set of Customizing settings Which are grouped according to logical, business management criteria to a unit. For documentary,
Java applications are typically deployed in multiple environments and platforms, each requiring some unique configuration. JFig gives developers a simple yet powerful tool to manage their applications’ configuration. It allows them to:
1. Store application configuration in one common repository of XML files
2. Access configuration data using one common, convenient interface
3. Easily define multiple configurations, dynamically modifying those variables that need to change in different situations
4. Eliminate the error prone practice of defining the same configuration variables in multiple locations
5. Ease the management, deployment, and control of configuration files
jConfig is an extremely helpful utility, arming the developer with a simple API for the management of properties. Parts of the implementation are based on the idea that Properties, from Java's perspective, are a good thing, but can be better. jConfig employs the use of XML files for storing and retrieving of property information. The information can be stuffed into nice categories, which makes management quite a bit simpler. The ability to load from a URL is also a nice feature. It allows for a central repository where multiple instances of jConfig can read a single file. The nifty ability to
switch between XML and Properties files isn't fully exploited yet, but will be coming soon. That will mean that the developer would take their existing Properties files and export them to XML. That means less time to get up and get going with jConfig.
With jConfig we hope to have provided the developer with another powerful accessory for his or her's toolbox.
This is a guide to running Linux with the Dell XPS M1710 notebook. The XPS M1710 is a very high end notebook with a big screen and fast components. It is also very heavy. Linux support is top notch.
This is the collection of Linux-related tips and tricks, mostly administration and configuration that helps to integrate Linux system into Windows office environment.
In order to force all DomUs to shutdown, instead of suspending, during Domain 0’s shutdown, all you have to do is make following changes in /etc/sysconfig/xendomains: Leave empty the XENDOMAINS_SAVE variable. By default, it uses /var/lib/xen/save as the directory where the states of the DomUs are saved. By leaving it empty, the states of the virtual machines are not saved, but they are shut down as usual.
