Jacman is a GUI frontend to ArchLinux's "pacman" package management system. It provides an attractive interface to the majority of key features of Pacman, including installing, removing, and updating packages. It also includes "rollback" functionality to return back to an older version if necessary.
Juxy is a Java unit testing library for XSLT. It allows you to write JUnit tests for XSLT stylesheets. You can easily setup transformation context (parameters, variables, current node) and then invoke the transformation. There are corresponding methods to call or to apply individual templates and you can even pass parameters to these templates, or apply templates in different modes. Result of the transformation can be verified in a number of ways; you can evaluate an XPath expression or you can perform canonical XML comparison. It works with any XSLT processor that supports the TRaX API.
The Kitikat Java Framework is a powerful but simple Datastore processing framework. A Datastore represents an in-memory copy of data. A program may retrieve the data from a data source, such as a relational database, manipulate the data, and then propagate the updates of the data back to the original data source or to a different data source. Once the data is retrieved, it is a disconnected, data source independent version of the data. A change history of the data is maintained to provide dynamic updates to a data source, and there are several levels of concurrency control provided for multi-user environments.
Simple Log is a small library that does logging very simply and requires you to do almost nothing (other than actually logging) to get log output to happen. It is much simpler to use than a logging framework, especially in terms of configuration. It doesn't attempt to solve every logging problem in one package, but contains enough features to be a viable alternative for most applications that need logging. This tool will handle the logging needs of most small- to large-sized projects, but with an almost non-existent learning curve.
mod-vhost-ldap is an Apache 2.x module for storing and configuring virtual hosts from LDAP. It supports DocumentRoot, ScriptAlias, ServerName, ServerAlias, ServerAdmin, and SuexecUserGroup directives. It's built on top of mod_ldap, so it uses its caching capabilities and can be used with a threaded Apache httpd.
Chessweb is a J2EE chess game Website. It is a pure Java servlet implementation of a two-player chess game. Two players log into the Web site, see an image of the current board in their browser, and make their moves. The differentiating features of chessweb (e.g. versus WinBoard / XBoard) is that it's an extremely lightweight implementation written completely in Java (nothing more than an app server and browser is required). Furthermore, the client end is DHTML only, and verified to works with FireFox 1.0.6 and IE 6.
