The project's aim is to provide a self contained pure Java (platform independent) common infrastructure for developers of trading systems. Some of the aspects which should be addressed are to provide a common SQL92 compliant database schema for storing financial data, common Java interfaces for how to interchange data between different modules, visualisation of raw financial data and trading signals and several other common aspects needed to create a final trading system.

Selenium Remote Control (RC) is a test tool that allows you to write automated web application UI tests in any programming language against any HTTP website using any mainstream JavaScript-enabled browser.

JWebUnit is a Java-based testing framework for web applications. It wraps existing testing frameworks such as HtmlUnit and Selenium with a unified, simple testing interface to allow you to quickly test the correctness of your web applications.

HtmlUnit is a "browser for Java programs". It models HTML documents and provides an API that allows you to invoke pages, fill out forms, click links, etc... just like you do in your "normal" browser. It has fairly good JavaScript support (which is constantly improving) and is able to work even with quite complex AJAX libraries, simulating either Firefox or Internet Explorer depending on the configuration you want to use. It is typically used for testing purposes or to retrieve information from web sites.

Here are snippets from my Flex code, and my Acegi configuration. If you notice, what we did, was set up Acegi, so it's successful and unsucessful authentication url's point to XML documents that contains the result of the login.

Developers can spend 90% of their time working around browser quirks. In addition, building, reusing, and maintaining large JavaScript code bases and AJAX components can be difficult and fragile. Google Web Toolkit (GWT) eases this burden by allowing developers to quickly build and maintain complex yet highly performant JavaScript front-end applications in the Java programming language.

The m2Eclipse project, provides support for Maven within the Eclipse IDE, and, in this chapter, we will explore the features it provides to help you use Maven with Eclipse.

On the off chance that other people find this helpful, here's how I set up Tally-Ho to work in Eclipse with the Sysdeo Tomcat plugin and Maven 2.

In this article, we describe how to use BlazeDS Remoting to seamlessly integrate the two technologies and build state-of-the-art internet applications made of a Flex front-end and a Spring back-end.
