Mastering Ajax, Part 4: Exploiting DOM for Web response


Mastering Ajax, Part 4: Exploiting DOM for Web response
The great divide between programmers (who work with back-end applications) and Web programmers (who spend their time writing HTML, CSS, and JavaScript) is long standing. However, the Document Object Model (DOM) bridges the chasm and makes working with both XML on the back end and HTML on the front end possible and an effective tool. In this article, Brett McLaughlin introduces the Document Object Model, explains its use in Web pages, and starts to explore its usage from JavaScript.

Demystifying class loading problems, Part 1: An introduction to class


Demystifying class loading problems, Part 1: An introduction to class loading and debugging tools
The class loading component is fundamental to the Java virtual machine. Though developers generally have a good grasp of the basics of class loading, when a problem occurs, they may have a hard time diagnosing and determining a solution. In this four-part article series, Lakshmi Shankar and Simon Burns discuss the various class loading problems that you may encounter in your Java development and illustrate why they occur and how to resolve them. The insights they provide should help you understand and resolve common Java exceptions, such as NoClassDefFoundError and ClassNotFoundException, in addition to more challenging problems, such as class loader constraint violations and deadlocks. In this first article, they describe in detail how Java class loading works and discuss the tools available in the JVM to help you diagnose class loading problems.
