[2004-01-26] JMX Boosts J2EE Application Management
As J2EE adoption grows, the business use and importance of J2EE application deployments are on the rise. Increasingly, mission-critical applications are being built and deployed on J2EE infrastructures. This trend is driving the demand for better administration, monitoring, and management of J2EE applications, as well as the underlying network and systems infrastructure. The software industry has widely recognized the importance of J2EE application management to enterprise IT, and has been seeking ways to address this growing need. However, awareness of enterprise J2EE deployment issues and how to best address this need are only now emerging.
[2004-01-08] Using J2EE to Drive J2ME Applications
Wireless technology is evolving at a rapid pace. There is a lot of talk about mobile and wireless computing and there is also a fair amount of hype. However, the one thing that is conspicuously absent from much of these discussions on mobile and wireless computing is a discussion on what these devices are connecting to. The fact is, most of the value, in terms of content and capabilities of the device, is a result of interacting with a server of some type. This is true whether we are talking about microbrowsers such as WAP and iMode, J2ME clients, or short message service (SMS) and email. Behind the scenes these devices are interacting with services that reside somewhere on a network. These services handle much of the complex details of the features offered by wireless devices. Although there are complexities that the mobile device must deal with, a well-designed wireless architecture delegates as much complexity as possible to the server. This is desirable because servers have more processing capabilities and do not have the power restrictions of mobile devices (i.e., servers don't run on batteries that are worn down by the CPU). This article examines wireless computing from the server's perspective. First, the problems of wireless computing or the public Internet are discussed. Then various models that help address these problems are provided.
[2004-01-06] Using JMX to Manage Web Applications
The Java Management Extensions (JMX) standard is gaining adoption within the J2EE community for the management of applications, as well as application servers and other infrastructure software. JMX makes it possible to manage and monitor applications using a choice of management systems and consoles, including SNMP consoles. It also simplifies the task of making applications manageable, i.e. management instrumentation, and enables improved management of deployed applications in the enterprise.
