BEA WebLogic Server (WLS) is the most widely deployed J2EE application server and continues to be an attractive platform for many enterprise-class situations. As part of its support for J2EE 1.3, WLS now embeds a Java Message Service (JMS). The implementation is straightforward; using many built-in WLS features, it proves worthy at moderate scale in predominantly WLS environments. Despite the inclusion of a new JMS implementation, there remain instances where heterogeneity, scalability, and availability requirements go beyond native support, calling for increased sophistication provided by third-party messaging solutions. For example, when multiple brands of application servers, C clients, or non-Java legacy applications are involved, a solution with broader platform coverage is required. If specialized features like client-side persistence or large-message suppor... (more)

Advanced JMS Design Patterns for WebLogic Server Environments Part 2

Part 1 of this article (WLDJ, Vol. 1, issue 8) explored third-party Java Message Service (JMS) integration into WebLogic Server (WLS) and addressed related issues. In Part 2, we'll implement transactional JMS design patterns using SonicMQ and the WebLogic Server Adapter (WLSAdapter) as the JMS solution. Included in this discussion are the message-driven bean (MDB), message-producing bean (MPB), and message- consumer bean (MCB). Pattern 1: Message-Driven Bean with a Queue Listener This design pattern is used with the WLSAdapter to create and configure an MDB that will be used with ... (more)

Enterprise Portal Integration and The Enterprise Service Bus

The high interest in business visibility, flexibility, and knowledge management has made portal technology a popular choice for monitoring, searching, and managing business activity across the enterprise. BEA WebLogic Platform provides an attractive platform for building highly dynamic enterprise portals that can aggregate, organize, and present information from multiple back-end systems. Whether the portal is implemented with the feature-rich environment of WebLogic Portal Server, or through an MVC framework such as "Jakarta Struts", the newest release of BEA's 8.1 platform pr...

Enterprise Portal Integration and the Enterprise Service Bus Part 2

Enterprise portals have become the most popular method of offering a common user interface to a suite of services across the enterprise. Offering business visibility, flexibility, and knowledge management, portals promise users the ability to monitor, search, and manage business activity across the enterprise. However, as portals mature from basic offerings to more complex sets of services, they will require a robust, agile, and pervasive integration network to provide critical business services to portal users in real time. The Enterprise Service Bus (ESB) not only provides the... (more)
