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.

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 Part 2

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)
