Most Web-based applications today confine users to the frame of their browser, restricting them to viewing only one Web page at a time. Technologies such as JavaScript make additional browser windows possible, but this approach doesn't enable the kind of customized menus, toolbars and windowing features available in a traditional client/server application. Java Swing provides additional capabilities such as the ability to create windows outside the browser that have the look and feel of a traditional client application. The techniques described in this article can be used to migrate traditional client/server applications to a Web-based environment. Event-monitoring applications that display and continuously update event information in real time stand to benefit from such an approach. For example, applications that monitor changes in financial data, network activity o... (more)

Real-Time Applications with Java and CORBA

Common Object Request Broker Architecture and Java are among the newest emerging technologies revolving around IP and Internet applications. The CORBA specification defines an industry-wide standard infrastructure that simplifies the integration of software systems using object-oriented techniques. CORBA separates architecture and implementation from interface specification, allowing clients and servers to be implemented in any language, on any platform. Java is an excellent, network-savvy, object-oriented language that's well suited for implementing CORBA components. Java's obj... (more)

Java Collections Framework & Managing Data

Every application has to consider how its data is stored, manipulated, and accessed. Fortunately for Java developers Sun provides commonly employed data structures as part of the Java platform in the Java Collections Framework (JCF). A framework is a set of well-defined interfaces that, if used properly, can benefit productivity tremendously, increase reusability, reduce software costs, and improve quality. The JCF acts as a supporting structure for data manipulation. Well-thought-out choices in this arena make the difference between superior-performing software modules that are... (more)
