* BlueBream is built on top of the Zope Tool Kit (ZTK), which has many years of experience proving it meets the demanding requirements for stable, scalable software. * BlueBream uses the powerful and familiar Buildout system written in Python. * BlueBream employs the Zope Object Database (ZODB), a transactional object database providing extremely powerful and easy to use persistence. * BlueBream registers components with Zope Component Markup Language (ZCML), an XML based configuration language, providing limitless flexibility. * BlueBream features the Zope Component Architecture (ZCA) which implements Separation of concerns to create highly cohesive reusable components (zope.component). * BlueBream implements Python Web Server Gateway Interface WSGI using Paste, PasteScript, and PasteDeploy. * BlueBream includes a number of well tested components to implement common activities.

* The GWT SDK provides a set of core Java APIs and Widgets. These allow you to write AJAX applications in Java and then compile the source to highly optimized JavaScript that runs across all browsers, including mobile browsers for Android and the iPhone. * Constructing AJAX applications in this manner is more productive thanks to a higher level of abstraction on top of common concepts like DOM manipulation and XHR communication. * You can debug AJAX applications in your favorite IDE just like you would a desktop application, and in your favorite browser just like you would if you were coding JavaScript. The GWT developer plugin spans the gap between Java bytecode in the debugger and the browser’s JavaScript. * GWT contains two powerful tools for creating optimized web applications. The GWT compiler performs comprehensive optimizations across your codebase — in-lining methods, removing dead code, optimizing strings, and more. By setting split-points in the code, it can also segment your download into multiple JavaScript fragments, splitting up large applications for faster startup time. * When you’re ready to deploy, GWT compiles your Java source code into optimized, stand-alone JavaScript files that automatically run on all major browsers, as well as mobile browsers for Android and the iPhone.
