The target of JCustomizer project is the generic and persistent customization of every Java Swing/AWT GUI at runtime: fonts, colors, texts, accelerators, ... A nice accompaniment is a WYSIWYG access to internationalization without programming efforts.

[This project is frozen, but has an offspring with more features: https://github.com/jeffhain/jadecy ] JCycles provides treatments to compute cycles, or just strongly connected components, in directed graphs in general, or in classes or packages dependencies graphs parsed from class files (major version <= 51, else does best effort). It uses Tarjan's algorithm for SCCs, and Johnson's for cycles, with continuations instead of recursion, which allows to handle large graphs (< Integer.MAX_VALUE vertices). Requires Java 5 or later.

JDice rolls dice. A simple yet rich language allows to express several kinds of roll schemes, including any dice type, rerolling, selecting highest/lowest, counting, etc.

The purpose of the project is to build a world class open source Enterprise integration engine. <br>Uses of JEngine include healthcare systems/hospitals HL7 interface engine, intergration of HL7 with EMR and Practice Management Systems.

JFlightLog is a FREE, graphical pilot log for Ms Windows and others(it's java). Saves as Excel XLS, PDF, CSV or TXT. Imports CSV from other logbook programs or spreadsheets. Prints entries directly. Auto-creates charts for visualizing flight times.

Flight planning tool, designed for General Aviation pilots. Includes Aviation Weather Center METAR and TAFs queries.

JFractals is a fractal generator written in Java. JFractals allows you to zoom into Julia sets and the Mandelbrot set. JFractals supports multithreaded rendering, antialiasing and multiple colouring methods.

Plotting of mathematical functions, including math expression evaluation

GPS (NMEA 0183) extensible communication library written in Java. Handles standard GLL, GGA, RMC, GSA and GSV sentences and may be extended on application-level for handling any other sentence types. Bundle also contains GUI- and console-based GPS tool.

A Java Implementation of Latent Dirichlet Allocation (LDA) using Gibbs Sampling for Parameter Estimation and Inference

jLips is a lightweight Java persistence container that implements database persistence through Java interfaces through a defined field naming scheme. Can be used with any JDBC database. jLips has a very small footprint and a simple interface.

Lattices and ordered sets visualization tool

JMapDesk is a Java-Swing application to the UMN MapServer on the base of the shp2img tools (FWTools) similar to Sourcepole's Mapdesk. The UMN MapServer is a well known online map server software. MapServer is being configured through a so called Mapfile

JOrigami is a collection of algorithms for computational origami. Some algorithms studied by computational origami does not have an implementation. JOrigami solves the famous and funny fold-and-cut using Demaine's disk packing implementation.

JPARSEC is a Java Package of Astronomical Resources for Standard Ephemerides Calculations, focused on accuracy, documentation, 2D/3D charts, realistic planetary rendering, and Astrophysical modeling. For source code visit http://conga.oan.es/~alonso/

Java library that interfaces with "The USB INSTEON PowerLinc Controller" built by Smartlabs Design. This library is built on top of the javax.usb linux reference implementation, but should work under Windows as well.

JPOP is a pure java parallel optimization package based on the Optimization Java Package. It supports analytical gradients and Hessians for non-linear optimization. JPOP is based on uncmin in Fortran but employs java arrays and object oriented code.

PhysX adapter for java. Translates full functionality. Utilizes type safety, polymorphism, inheritance, and other java stuff.

JPowerFlow - a steady state electric power system power flow solver.

Java Quine McCluskey (JQM) implements the Quine-McCluskey algorithm with Petrick’s Method for minimizing Boolean functions. Designed for both education and industrial application, it handles up to 16 variables and functions. Uniquely, JQM bridges the gap between theory and practice: it visualizes the solution process with generated Karnaugh Maps for students, while supporting PLC engineers by exporting results to Structured Text (ST) and Ladder Diagram (LD). The software includes a GUI for managing truth tables and supports diverse file formats for import and export.

JQuadRobot, developed in Java and Java3d API, is designed to control a custom Quadruped Robot. The project contains two software components: editor for movement control and a simulator.

JQuantity is a set of Java classes which enable developers to build scientific applications using quantities which are either exact or have known (bounded) errors. Quantities may include units, may be complex, non-scalar, etc. Extends java.math classes

JRandO is a test data generator or better test object generator framework. It can be used in JUnit tests or in performance test (for e.g. using JMeter). It may also be useful in anonymization of data or in a simulation environment.

JRobot is a Java utility intended for the manipulation of the Mitsubishi RVM1. It provides the possibility to connect locally and remotely to RVM1 robots, manipulate with joysticks and has a virtual 3D view intended for simulation.

The JScrollDesktopPane swing component provides a virtual desktop replete with dynamic scroll bars, dynamic menus, and dynamic button shortcuts.
