Struts is a Jakarta project that provides a J2EE framework for building Web applications. It is based on a Model 2 approach, a variant of MVC. Struts provides its own Controller component and integrates with other technologies to provide the Model and the View. For the Model, Struts can interact with any standard data access technology, including Enterprise Java Beans, JDBC, and Object Relational Bridge. For the View, Struts works well with JavaServer Pages, Velocity Templates, XSLT, and other presentation systems.
OSCache is a high performance J2EE caching solution that can cache portions of JSP pages, entire HTTP responses (including dynamically generated images), and arbitrary Java objects. It can provide your J2EE application with huge performance gains and graceful error tolerance (e.g., in the event of a DB failure, cached content is served).
The JGenerator is a Web server production application that can dynamically combine text, graphics, and sound to build rich Flash content. It is a free alternative to and analog of Macromedia Generator. It supports most of the Macromedia Generator features, uses the same data format and the same set of commands, and emulates its behavior.
mod_backhand is a load balancing module for Apache. It provides per-request HTTP redirection within a heterogeneous Apache server cluster. Each request is processed and run through a set of "candidacy functions" to determine which server is best suited to respond. The request is then proxied to that server. Facilities are in place to allow you to write your own dynamically loadable decision making algorithms. Everything about the request and the current availability of resources can be used in the decision-making process.
4Suite XML is a Python-based toolkit for XML application development. It features a library of integrated tools for XML processing, implementing open technologies such as DOM, SAX, XPath, XSLT, XInclude, XPointer, XLink, XUpdate, RELAX NG, and XML/SGML Catalogs. The RDF and Repository components of 4Suite are separate packages that must be installed separately, on top of 4Suite XML.
apt-got is a customizable mirror engine. It works like a highly specialized proxy. It employs several pluggable modules that are customized for specific jobs. The first available module builds and supervises a partial (or full) Debian mirror which is populated on-the-fly by apt-get requests. There is also a simple mirror module that can be used to mirror source directories or even (static) Web pages. For increased performance on already-cached files, it employes its own Apache module. It supports customized mirroring algorithms.
