This is beneficial for any asynchronous messaging effort, and provides a basis for future JMS development. A generic access path for sending JMS messages is provided. We will also cover setting up a JMS topic within WebLogic 7.0. A sample message-driven bean is provided as well. Program communication is generally "synchronous," meaning that the client sends a request and waits for a response (e.g., client/server or distributed object RMI call). Asynchronous messaging provides an alternative means of program communication in which the initiating program writes a message to the JMS session, and the WebLogic container ensures delivery. The initiating program does no... (more)

I recently had the good fortune to participate in a review... (more)

Testing Web services creates an entirely new set of problems for development and testing teams. JUnits can be created to test parts of the Web service, but do not provide the overall functionality needed to ensure adequate validation, and make updating data values difficult. There are also many Web service components to be tested that do not find their way into other, more generic testin... (more)

Development Using Servlet 2.3 Filters and Event Listeners

With every release of the Servlet API new features are added that offer new functionality and provide developers with more flexibility when designing new Web applications. With a changing user base and business requirements, most developers would prefer an easy, cost-effective solution to shape their applications rather than rearchitecting existing applications. The application event list... (more)

Mercury Interactive's LoadRunner

Its ability to create large volumes of data is legendary, and its ability to monitor the systems being tested provides great value. The J2EE Transaction Breakdown Diagnostics Module, LoadRunner, brings detailed J2EE transaction analysis into the mix. Figure 1 illustrates at a high level the degree of monitorin... (more)
