JSXP is a web application framework for Java. Its main features are compile-time safety when accessing view elements, separation of code and design, simple XHTML design, component orientation, human-readable URLs, server side state managed automatically by the framework, view Flows (units of work that have one entry point view and a defined set of result views), AJAX support, internationalization, and resource management.
Openbakery Translation is an internationalization tool for Java. Unlike standard i18n in Java, openbakery translation uses the text in the default locale as the key. There is also a tool which checks all of the source code for translations. This tool then provides a list of key/value pairs which have to be added to a certain resource file, and another list of pairs which can be removed. The translation works by simply calling a static method called "translate". The code works out of the box, without writing any properties files. You only write properties files when you really translate the program to a second language.
Yeast is a tool that manages dependencies between program resources (e.g., Java jar files). It comes with a mechanism to download needed resources from a central repository and stores these resources in a local repository. This allows reuse of resources between different projects.
