An Introduction to Java This tutorial helps you to rapidly master the simple steps required to create Java applets. If you already know C++ then learning Java is particularly painless. Drawing Textured Spheres Rendering graphic effects on a spherical surface requires a sophisticated mix of programming and math. Follow along as Merlin Hughes walks us through rendering Java image objects using classes from the java.awt.image package. The result - a textured Easter egg with perspective. Thread Synchronization in Java Christopher McGee offers an elegant solution to the thorny issue of synchronizing multiple threads in Java apps. ITI’s GridBLT Learning Tool: Exposing Java’s GridBagLayout Class Java's GridBagLayout class is a notoriously difficult layout manager to learn. Steve Johnston, a developer at ITI, created a slick tool called GridBLT to help developers burn the GridBagLayout learning curve. Here's an introduction to the tool as well as a tutorial on GridBagLayout itself. Custom Class Loaders Using Java Kelly Campbell serves up a neat little custom Java class loader. An Introduction to Servlets, JSP, and Servlet Engines There are many programming alternatives to classic CGI programming, however, one of the most powerful and useful alternatives is Java Servlets. This article will give you the necessary basics for understanding what Servlets are and the benefits to using them. You will also learn how they relate to JSP and how to set up your own Servlet Engine. Building a Better Servlet Servlet technology is rapidly becoming the optimal choice for server-side programmers. With its "Build Once Run Anywhere" ideal, Servlets allow developers viable and powerful alternatives to standard CGI programming. By inheriting all the power and flexibility of the JAVA API, they can do almost anything you want quickly and efficiently. Enterprise CORBA – Chapter Six: "Object Location" A discussion of how clients find the object references they need on a network – looks at both CORBA compliant and ORB specific object location services. Using CORBA to Create Client/Server Applications In their three-part series, Understanding DCOM, authors Marshall Brain and William Rubin cover the ABCs of client/server application development using DCOM. Here, Marshall teams up with Christopher McGee to offer the same concise introduction to distributed application development, this time using CORBA. Tracking Down Java Class File Dependencies Alan introduces a tool he wrote in Java for mapping out the class dependencies in a Java project. CORE Java Foundation Classes – Chapter One: "Introduction to the Java Foundation Classes" Perhaps the best Java Book out there, Topley's book lifts the hood on Swing. Chapter One begins with a rich history of the JFCs and an overview of their evolution, then goes right to Swing.

Essential JNI: Java Native Interface – Chapter Four: "Hello JNI World" A powerful 17-page introduction to programming for the Java Native Interface – JNI. Gordon walks us through the ABCs of JNI programming, complete with sample code and illustrations. Multiple Inheritance in Java Alan offers some ideas on how Java developers can mimic multiple inheritance within Java code. Java POOP – Chapter One: "A Revisionist History of Programming" In this chapter excerpt, enjoy a funny and easy to read rendition of programming history that leads up to the motivations behind Java. A Dynamic Site Menu in Java for Internet Explorer 4 Alex walks us through a Java-based approach to creating a dynamic "explorer-style" (i.e., expandable) Web site menu that functions much like a Windows directory tree.
