The Grinder is a Java load testing framework that makes it easy to run a distributed test using many load injector machines. It is freely available under a BSD-style open-source license.

Part 2 in this series discusses how to integrate PHP and Java with two other methods. The first method—bridging—allows you to use Java objects from PHP, exposing another method of placing messages on JMS queues from PHP through Java. The second method of integration is using Streaming Text Orientated Messaging Protocol (STOMP), another protocol you can use to communicate with the ActiveMQ implementation of JMS. When ActiveMQ receives the message, it places it on the JMS queue, and the Adobe Flex application receives the message.

This article takes a look under the covers of the <f:ajax> tag and introduces another supporting API that has been added to JSF 2: the component client behavior model. We'll see how client behaviors can be used not just for enabling Ajax, but also for attaching arbitrary client-side functionality to JSF 2 UI components.

There are a number of ways to communicate between Flex and PHP but one of the more interesting is over sockets. Socket communication lets developers create near real-time communication by pushing information directly to the client. In this article you'll see the basics of how to use PHP as the socket server and connect it to a Flex application.

Parancoe is a Java meta-framework aggregating in an useful way Hibernate/JPA, Spring 2, Spring MVC and, for the AJAX support, DWR.

Multi-Mechanize is an open source framework for web performance and load testing. It allows you to run simultaneous python scripts to generate load (synthetic transactions) against a web site or web service.

Have you ever wished that Cookies were a lot bigger so you could store more data on the client, or that you could make cross-domain Asynchronous JavaScript and XML (Ajax) calls? If so, you are in luck. Both of these techniques can be accomplished using invisible Flash. So, just what is invisible Flash? It is not really invisible, however, it is 1 pixel by 1 pixel, which makes it pretty hard to see. And, it can be used as a way to tap into the capabilities of the Flash Player. In this article, you will learn how to build invisible Flash files that let you to store up to 100 KB of client-side data and make cross-domain Ajax calls—all without your users ever knowing that Flash is being used.

TourBus is an intelligent website load testing tool. Allows for complicated testing scenarios including filling out forms, following redirects, handling cookies, and following links—all of the things you’d normally associate with a regression suite or integration testing tool. The difference is that TourBus also scales concurrently, and you can perform hundreds of complicated regression tests simultaneously in order to thoroughly load test your website.
