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 listener and servlet filter features are included in the Servlet 2.3 API for these kinds of tasks and much more.

You have a consistent series of applications, so adding advanced monitoring capability should be fairly straightforward. Unfortunately, you soon find that frequently this is not the case. Most monitoring applications are built to support a v... (more)

Step-By-Step EJB 2.0 Inheritance in WebSphere

One of the vital principles of object-oriented programming is inheritance. Although not formally supported by the EJB specification, the need for inheritance in the EJB world has real importance. WebSphere Studio Application Developer supports inheritance of EJBs using a direct single-table approach (single table mapping) or a parent-child approach in which foreign keys are used between t...
