JavaScript EE, Part 3: Use Java scripting API with JSP
In the previous two parts of this series, you've seen how to run JavaScript files on the server and how to call remote JavaScript functions with Ajax. This article explains how to use server-side JavaScript code with the JavaServer Pages (JSP) technology and how to build Asynchronous JavaScript and XML (Ajax) user interfaces that remain functional when JavaScript is disabled in the Web browser. The sample code consists of a small JSP tag library that you can reuse in your own applications as well as a dynamic Web form, which is generated with a piece of JavaScript code that can be executed on the Web server or in the Web browser.

Finite state machines in JavaScript, Part 2: Implement a widget
Part 1 of this series illustrated how to use a finite state machine to methodically design complex behavior for a simple Web widget -- an animated tooltip that fades into and out of view. In this article, you learn to implement that behavior in JavaScript and take full advantage of its distinctive language features, including associative arrays and function closures. The resulting code is compact and concise, its logic is transparent, and its animation performs smoothly even on heavily loaded processors. Part 3 will cover the practical issues of making the implementation work in all popular Web browsers.

Java development 2.0: JavaScript for Java developers
Java developers have historically perceived JavaScript as a toy language, both too lightweight for real programming and too clunky to be of use as a scripting alternative. And yet JavaScript is still around, and it's the basis of exciting web technologies like GWT and Node.js. In this installment of Java development 2.0, Andrew Glover explains why JavaScript is an important tool for the modern Java developer. He then gets you started with the syntax you need to build first-class applications for today's web, including JavaScript variables, types, functions, and classes.

Visualize in-browser performance data with R and JavaScript using the W3C performance object
When looking at web performance metrics, the ideal numbers to focus on are real user metrics harvested from your own users. The most popular method is to consume your machine data with a tool such as Splunk, which enables you to analyze and visualize your access and error logs. With these tools you can glean some aspects of performance data, such as file I/O times for reading assets and access times of API requests. However, you are still left to extrapolate client-side performance data, put beacon calls at certain high-level checkpoints, or just run synthetic testing with tools like WebPagetest. Now, the W3C has standardized an API that makes it possible to capture and report out in-browser performance data by using the Performance object, an object native to the Windows object in all modern browsers.

Implement a real-time server push in Ajax applications using socket-based RIA technologies
The new range of advanced user interface (UI) applications requires some aspect of the "server-push" feature so clients can be notified immediately of any server-side changes. Unfortunately, the HTTP spec does not address the issue of any server-side initiated communication, so the server-push has traditionally been implemented through client-side polling. This technique tends to generate a lot of unnecessary traffic and non-optimized applications. Thankfully, certain Rich Internet Application (RIA) technologies do allow the opening of a dedicated socket channel, with the back-end server providing an opportunity for Asynchronous JavaScript and XML (Ajax) applications to piggyback on their APIs and implement a server push. This article explores this technique in a variety of ways, and helps you understand it well enough to begin your own implementation.

Explore multithreaded programming in XUL
As you create cross-platform desktop applications using XUL, you also can enhance your skills with JavaScript, CSS, and even HTML. XUL's cross-platform capabilities are not a collection of least common denominator features. Instead, XUL gives you the kind of power that you might expect from a desktop application toolkit, including access to native threads. You can even access native threads directly from JavaScript, writing code that executes in parallel. In this article, you will examine the multithreading capabilities of XUL, and create an application that uses multiple threads to retrieve data. You will take a classic IO-bound application, one that accesses multiple remote data sources over the Internet, and speed it up through multiple threads in XUL. The application will allow users to view and compare anonymous results of three popular search engines: Google, Yahoo, and Bing from Microsoft(R).
