AuthenticRoast allows you to build highly flexible authentication mechanisms for the Java Web tier. This can be anything from HTTP Basic authentication to authenticating with openid, facebook, or your company's Kerberos setup. The authentication modules can be combined at will and even changed at runtime. This currently works for glassfish and plain Tomcat, and allows you to use all the features of container-managed security without being constrained to the simple login methods provided.
BoneCP is a Java JDBC connection pool implementation that is tuned for high performance by minimizing lock contention to give greater throughput for your applications. It currently beats all known connection pools, including C3P0 and DBCP, as shown on the benchmark section on the site.
DynamicReports is a Java reporting library based on JasperReports. It allows you to create dynamic report designs and it doesn't need a visual report designer. You can very quickly create reports and produce documents that can be displayed, printed, or exported into many popular formats such as PDF, Excel, Word, and others.
Java Classic RPG is an RPG framework, engine, and game that uses OpenGL, a challenging AI, huge territories, and classic pen-and-paper turn-based combat. It is in the tradition of games like Wizardry 7 and EOB, but incorporates innovations made possible by modern computing technology. The framework and engine feature a self-containing, playable, algorithmically-generated world, and can be the base for new games.
SDLbits is a very lightweight SDL wrapper for Java. This library was designed to be very small and simple. It does not use Swig, but goes directly from "native" Java definitions to the sdlbits C wrapper library to SDL or OpenGL (in C). All symbols are exposed as they would be in C, except the "SDL_" prefix has been removed, since all names are inside the SDL class. The SDL structures from C are translated to very simple Java classes, such as SDL.VideoInfo. Most fields are exposed as read-only "get" methods, but "set" methods for writable members are supported as well. These classes simply interface to the actual C data with a ByteBuffer "pointer".
Sonar enables you to collect, analyze, and report metrics on source code. Sonar not only offers consolidated reporting on and across projects throughout time, but a central place to manage code quality. With no complex infrastructure, Sonar fulfills needs in terms of code quality, whether it is to make an audit or implement a continuous improvement process.
