| Service Components: The Quickest Path to a SOA |
|
|
| The emergence of the Enterprise Service Bus (ESB) over the past two years has spurred the deployment of componentized applications based on a Service Oriented Architecture (SOA). SOA enables the development of business systems and processes with loosely coupled components (often called services) facilitating business agility. Much of the industry' s focus has been on the architecture of the underlying ESB infrastructure that supports an SOA.

| AOL Offers Free E-Mail, Web Services |
|
|
By Anick Jesdanun
AOL will give away e-mail accounts and software now available only to its paying customers, marking the end of an era for a company that grew rapidly in the 1990s by making it easy to connect online. "This is the final goodbye to the days when AOL was the king of the Internet," said Jeff Lanctot, general manager of aQuantive' s Avenue A/Razorfish.

| Developing Web Applications in a Clustered Environment Using WLST and BEA Workshop |
|
|
| A development environment typically consists of a single-server J2EE container for unit testing Web and enterprise J2EE applications. In contrast a production environment is far more likely to be a complex, clustered configuration. Problems discovered during production-level testing often require looping back to the development team for modification of the Web or enterprise application. Many of these issues can be caught earlier in the cycle by having the development team perform unit testing against a clustered environment. This tutorial presents a straightforward way for developers to try their applications in a cluster by utilizing the WebLogic Scripting Tool (WLST) to automatically provision applications into this environment.

| Content Personalization: Planning and Implementation |
|
|
| Content personalization seems simple: Certain users should be able to access certain content while others should not. The concept, however, is deceivingly complex. While you may be tempted to jump in and start assigning entitlements to users based on arbitrary classifications, taking the time to properly classify users and content with an extensible model will go a long way in meeting your personalization needs far into the future. Classifying distinct users and content is a challenge. How can you best classify users such that you can easily and accurately target broad and finely focused audiences? How can you minimize the administrative overhead of maintaining the classification information of both users and content? To what level of granularity should the content be divided to support personalization? Finally, how can all this be implemented with BEA WebLogic Portal 8.1? Content personalization is certainly complex, but by logically tackling its issues, it need not be complicated.

| IBM Offers Prototype for Building 'Mashup' Apps |
|
|
| IBM earlier this month brought out a prototype technology that uses Web services and wiki technology to quickly build customized "mashup" applications that can blend external information, like news feeds and weather reports, with enterprise content and services. IBM defines mashups as applications that use open technologies such as Asynchronous JavaScript and XML (AJAX), PHP scripting language and syndicated feeds to combine content from more than one source into a single application.

Semantic interoperability is often overlooked or an afterthought in the development of a SOA. Application and data architects may have difficulty making informed architectural decisions about it. This article unveils the mysteries of semantic interoperability in a SOA context. We will first walk through the semantic spectrum, and then discuss the anti-patterns, patterns and best practices of semantic interoperability.

| Introduction to the WebLogic Diagnostics Framework (WLDF) |
|
|
by Rebecca Sly
The WebLogic Diagnostics Framework (WLDF) gives administrators and IT managers the ability to analyze their server operating environment using a set of components that generate information from WebLogic servers and the resources, including applications, deployed on the servers. The resulting data can then be gathered for analysis, and later persisted for long-term storage. This information (usually generated by MBeans) can be used to diagnose and resolve issues, monitor and maintain a history of events, carry out performance tuning, and perform many other useful tasks for a system administrator.

by David Burke and Darragh O'Flanagan
The IP Multimedia Subsystem (IMS) is the 3rd Generation Partnership Project' s (3GPP) vision for a converged telecommunications architecture that merges cellular and Internet technologies to uniformly deliver voice, video, and data on a single network. Currently one of the hottest topics in telecom, IMS is rapidly becoming the architecture of choice for operators who wish to upgrade their existing cellular and fixed-line networks.

| SOA: Are We Reinventing the Wheel? |
|
|
by Nick Simha
If you have been in the IT field for a while, you can' t help but get the feeling of déjà vu when you hear vendors pitching new technologies. If the buzz and hype around Service Oriented Architecture (SOA), makes your head spin, you are not alone. In a recent meeting, one participant who used to code in COBOL asked what was different between SOA and what he did with COBOL copybooks. I have never used COBOL copybooks, but having seen many technologies come and go, I can empathize with the question. In this article, I explain the primary motivation behind SOA and how technology has evolved to support SOA. I will keep my discussion at a conceptual level and refer to other publications at the end for those who want to delve deeper.

| Windows should rev up Web services |
|
|
| If you believed the early Web services hype in 2001, you would have expected that buying packaged applications should by now be well on the way to becoming passé, replaced by on-demand software services. And data, applications, business processes and identities would be nearing an integrated Utopia both within and outside your company walls. Instead, Canadian organizations are, at a very slow pace, just getting underway with deploying Web services.

| Fighting Cyberattacks By Sharing Information |
|
|
| Earlier this month, a series of worms--the first of which was named Zotob--took down a significant number of Windows 2000 PCs around the world. Microsoft issued a patch and said there was no threat to Windows XP systems unless the attacker had valid log-on credentials. About two weeks later, Microsoft discovered that wasn' t the case, and said the same vulnerability that Zotob used to victimize Windows 2000 systems also existed on some Windows XP systems.

| Auditing user accounts |
|
|
| With Sarbanes Oxley, HIPAA, GLM, and the other auditing compliance programs getting so much attention, all aspects of the network environment are under a microscope. For any operating system environment this includes the auditing of the user accounts and their related properties. Considering that many attacks are accessed through a user account that has one or more incorrect and insecure settings, it makes sense to focus on user account properties during the audit. Within a Windows Active Directory environment there are the standard user properties that must be audited, plus a few that may not fall into too many other network environments. This article will discuss the key user account properties that need to be audited, as well as the tools that can help complete the task.

| Component-Oriented Enterprise Application Integration For The 21st Century |

| Even straight data is accessed using function calls and/or components that return standard data structures. With components (in the broad sense) so ubiquitous in today's enterprise, it's surprising to discover that "modern" application integration is actually pretty old fashioned—most of it is data-oriented, rather than component-oriented.
