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".
action4Java is a lightweight, modular, extendible, and recursive Java component framework. It contains some standardized actions and a data container. These actions are called when a comment tag is found. The action is controlled by the attributes within. Actions can have any purpose. Templating is just an action by itself. The template controls loading of data and storing to a file by itself, and runs independently from a Java development environment. It includes simple examples demonstrating looping within a page or creating several pages based on the data of a simple Excel sheet, and more.
