This tutorial shows how to use Flex's LiveCycle Data Services Express (DS) messaging features to implement "data push" in your Flex applications with the BEA Workshop Studio (Flex bundle). My aim is to develop a small Flex messaging application that sends and receives messages.... more »

Industry discussion on Service-Oriented Architecture (SOA) and virtualization positions them as separate, though related, topics today. Because of the wealth of public discussion on each technology, IT managers may wonder whether they are in any sense connected to each other. In fact, the technologies that come with virtualization can be seen as the key enablers for the flexibility promised by SOA. This paper establishes the technical links between these two popular developments in enterprise computing.... more »

Many organizations are adopting virtualization technologies as part of their drive to increase utilization and reduce infrastructure costs, and at the same time improve their ability to respond rapidly to new line-of-business initiatives. Hypervisor-based virtualization platforms, such as VMware's Virtual Infrastructure, have allowed them to consolidate their IT deployments onto a much-reduced number of servers running powerful multicore processors that now host multiple virtual machines running applications in their own protected, virtualized environments. As a result, they have been able to optimize their physical infrastructure by pooling hardware and storage resources, reducing physical space, easing power and cooling costs, and improving application availability.... more »

To reap the business benefits of SOA, enterprises need a set of conceptual blueprints and guiding principles. An SOA Reference Architecture provides this critical foundation. It offers an architectural framework for planning SOA-based projects that maximize interoperability and reuse. It defines a consistent vision of SOA throughout the enterprise. It supplies the context for imposing best practices on development and deployment. It represents IT's architectural alignment with the business objectives for SOA and thus helps drives decisions associated with the implementation of SOA, including infrastructure requirements and investment priorities. With an appropriate SOA Reference Architecture, enterprises can manage the expansion of SOA within their organizations from pilot projects and grassroots efforts to comprehensive adoption.... more »

My first blog entry....ever, as it's the only time I've thought I have something worth sharing! Feel free to comment - but be nice! Anyway, what's it about? Well - I've been using BEA Guardian for a few months in it's various versions and thought I'd share my experiences. The first version we had, was pretty bad in terms of performance - I would go as far as saying that in my environment it was pretty unusable. I had a look, thought it looked good, but clicking on an evaluation would grind my PC to a halt, so I gave up.... more »

What are tlog files ? Tlog files are the files used by weblogic to keep a trace of current transactions. For example, when an instance is restarted, the tlog files are used to perform the second step of a two-phase commit on a transaction that was in progress. Sometimes, when a transaction is corrupted, you've got to delete thes files to get rid of the phantom transaction. There is no need to restart a server to have them recreated.... more »

To develop client-centric Ajax applications, such as those that use the Dojo Toolkit, you need a JavaScript editor, a JavaScript debugger, and a message inspector to display the sequence of exchanges between client and server. This article shows how to install and use a free JavaScript editor and debugger from Aptana, Inc., in BEA Workshop. It also shows the use of a message inspector in the Firebug plug-in, an extension for Firefox. ... more »

An increasingly common scenario among BEA WebLogic Portal (WLP) customers is the use of BEA AquaLogic Enterprise Security (ALES) for personalization and fine-grained entitlements. One concern with substituting WebLogic Portal's built-in entitlements engine with AquaLogic Enterprise Security is performance. This article examines the effect on the performance of a WebLogic Portal application when AquaLogic Enterprise Security is applied to handle Visitor Entitlements.... more »

Andy Piper of BEA has just blogged on WebLogic Event Server - Why we used Spring. One key driver for BEA making Spring central to this product's programming model: Spring's ubiquity. "The answer is pretty simple - use something that developers are already familiar with. Hence, in a word, Spring."... more »
