MUSCLE (Multi User Server Client Linking Environment) is an N-way messaging server and networking API. It includes client-side networking APIs for various languages, including C, C++, C#, Delphi, Java, and Python. MUSCLE lets programs communicate over a network via streams of serialized Message objects. The included server program ("muscled") lets its clients message each other and store information in its server-side hierarchical database. The database supports flexible queries via hierarchical wildcarding, and "live" updates via a subscription mechanism.
The Lightweight Java Game Library is a native binding for OpenGL and OpenAL written with game developers in mind. It allows the full OpenGL and OpenAL APIs to be exposed without the penalties associated with competing methods, nor the limitations of APIs such as Java3D. Tutorials and demos are available, and Windows, Linux, and Mac OS X are supported.
ObjectDB for Java/JDO is a powerful yet compact Java Data Objects (JDO) Object Database (ODBMS), written entirely in Java, and compliant with the Java Data Objects (JDO) standard developed by Sun (JSR12). ObjectDB for Java/JDO is designed to efficiently handle databases of various sizes, ranging from a few KBs to hundreds of GBs. Among its features are small footprint, high performance, rapid development, easy deployment, and flexible architecture (1-Tier, 2-Tier, or N-Tier).
The DataBean package is a Java library that provides features for mapping a database table to a Java class (databean). The coding of the databean class must conform to a preset pattern so that the instances of the databean classes can perform common database operations without using much of the ugly SQL. DataBean is functional, stable, light-weight, and easy to use. It can make your application much easier to write when dealing with relatively unsophisticated database operations.
YAJOGLB (Yet Another Java OpenGL Binding) allows Java programmers to access their native OpenGL library. The library is implemented using Java's JAWT to access the native windowing system, along with JNI calls to OpenGL. Programs using the binding must use the shared library provided, since this is not a pure Java library.
JCons provides a library that bring color to your Java console. The Java console gives no methods to change the foreground or background color. With help of this library, one can make error messages red and success messages green, for example. Most Unix terminals can deal with ESC sequences, so they are used to make the Java console colorful.
MiGLayout is a versatile and flexible Swing and SWT layout manager. It uses string constraints or API type-checked constraints to format the layout. Strings are both short to type and easy to understand. MiGLayout can produce flowing, grid-based, absolute (with links), grouped, and docking layouts. It was created to be to manually coded layouts what Matisse/GroupLayout is to IDE-supported visual layouts.
JCmdLineProgress is a Java library to assist with progress reporting on the command line. Using simple hooks, a program can send progress messages and status information to the command line. Also, text based "spinners" can be used to provide visual confirmation that a long running but quiet program is still running. A working example is provided.
