It is delivered to standard web browsers thanks to XForms and Ajax technology, with no need for client-side software or plugins. Orbeon Forms allows you to build fully interactive forms with features that include as-you-type validation, optional and repeated sections, always up-to-date error summaries, PDF output, full internationalization, and controls like auto-completion, tabs, dialogs, trees and menus. Orbeon Forms is built around a user-friendly Ajax-based XForms engine, which brings standard W3C XForms to mainstream browsers, and the XPL engine, a mature, high-performance XML pipeline engine for processing XML data.
(WWB) is a Wicket component toolkit for displaying and editing JavaBeans. Web pages are automatically generated based on bean properties and conventions. If necessary, the layout, editability, and actions of these pages can be customized. At the highest-level, WWB's BeanForm component provides rich AJAX form functionality. The form is embedded in a Page designed by you. This allows you to create customized page designs and multiple BeanForms to be incorporated on a single page.Other lower-level components may be used independently of BeanForm (e.g., BeanGridPanel). BeanForm makes it very convenient to implement a bean-based form if you don't want to go to a lot of extra work. You focus on the model (beans), Fields within a form are dynamically sent back to the server-side bean as they are changed, which eliminates the typical form submit cycle. This makes WWB act more like a rich client application and less like a standard forms-based application.
AR for Java; ActiveObjects is an intuitive, pure-Java ORM. AO is designed from the ground up to be extremely simple and easy to use from an API standpoint. AO can be used with either an existing database schema, or it can auto-generate the database schema from the user-specified entity interfaces. ActiveObjects also supports Rails-style database migrations, allowing incremental changes and refactoring of the database schema without data loss.AO can perform better than data mapper ORMs due to its natural use of lazy-loading coupled with sophisticated caching mechanisms. However, performance is not the primary design goal of the project. Rather, the intention is to create an ORM which is powerful and yet extremely natural to use and integrate into your project. This design has lead to certain performance benefits (such as lazy-loading), but on the whole, data mapper ORMs are inherently slightly more performant than AO
