JBELT is a collection of procedure to create a PLM system oriented to connect the CAD application to the ERP database. Based on the web. The engine are JBoss, PostgreSQL and developed in Java on JBoss Seam framework.

JBean3D project aims to develop JavaBeans components representing classes in Java3D.

A simple Java ASN BER decoder and profiler A tool for easy manipulation of BER encoded files. An "awk" for ASN.1 BER (for Unix people) or maybe a "notepad" for ASN.1 BER (for Windows people). Jberd (Java BER decoder) is a lightweight BER decoder and associated tools for interpreting and processing BER encoded ASN.1 files. The following facilities are provided: • JBerd Profiler. A tool for profiling the contents of BER encoded files • JBerd Flattener. A tool for converting BER encoded files to flat files for processing by other facilities • JBerd Decoder objects. A set of Java facilities for writing BER applications that require BER decoding Go to the "files" section (link at the top of this page) to download a pdf of detailed documentation. Andrew Forsyth

JBotSim is a multipurpose dynamic network simulator that allows to quickly prototype a distributed algorithm and test its behavior on a set of static or mobile nodes. If mobile, the nodes can be controlled by the mouse or by program.

Planimetric Geometry (JCabri) is a rewrite of Cabri Geometry in Java. It provides solution for doing geometric constructions in 2D and exporting them as an animated GIF or Java applet.

The idea about this project is use it to create and provide a big data structures library, like trees, list and other.

JFacedec is aimed to build a flexible face detection system based on Java. The plug-in framwork makes it easy for you to share your own Training & Detection Algorithms, compare different methods and make progress together in this field.

Plotting of mathematical functions, including math expression evaluation

JFunctionViewer is a simple and fast OpenSource function plotter. Since it is written in Java it is Platform independend and can even be run from inside a Browser.

A library written in Java to manipulate GPX files. Also contained is a GUI program to visualize GPX files and the effects of manipulating them.

JGV is a Java applet that lets you embed movable 3D objects in web pages. Users can rotate, scale, translate, select and annotate the objects interactively. Also, JGV supports XML-based transmission of user events to the source web server over HTTP.

A set of utilities for working with the GAMESS Computational packages. Written in java to maximize cross platform use

JGraph is the most powerful, lightweight, feature-rich, and thoroughly documented open-source graph component available for Java. See the project homepage at www.jgraph.com for information and downloads.

JHeatChart is a simple Java library for generating heat map charts.

Lattices and ordered sets visualization tool

JMAT : Java MATrix tools package. Provides an easy-to-use class of matrix with MATLAB-like functions and syntax. JMAT also includes plots and histograms in 2D or 3D, an expression parser, and some statistic simulation tools.

JMagallanes is an open source end user application for Olap and Dynamic Reports written in Java/J2EE. Combines static reports, pivot table and charts. It reads from SQL and other data sources.

JMatrixView is aJava/Swing matrix viewer. It works with Colt matrix implementation. It features dynamically tunable row/column resolution and has been designed for sparse matrix.

JMicroPolygon is a project to provide polygon drawing and filling facilities for J2ME (MIDP 1.0 and 2.0) without relying on extension APIs.

JNeuron is an analysis tool for multi-neuronal spike train analysis. The tool will allow scientists to organize their spike train data analysis into projects. The tool will implement standard spike train analysis algorithms and also datamining algorithms

JPhylo is a Java based visualization program used to display sequences of phylogenetic trees.

JPlot is a multi-purpose data plotting program for use as the graphic front-end of (scientific) software. JPlot is also available as a stand-alone application with a complete and easy-to-use graphic user interface (GUI).

JProGraM (PRObabilistic GRAphical Models in Java) is a statistical machine learning library. It supports statistical modeling and data analysis along three main directions: (1) probabilistic graphical models (Bayesian networks, Markov random fields, dependency networks, hybrid random fields); (2) parametric, semiparametric, and nonparametric density estimation (Gaussian models, nonparanormal estimators, Parzen windows, Nadaraya-Watson estimator); (3) generative models for random networks (small-world, scale-free, exponential random graphs, Fiedler random fields), subgraph sampling algorithms (random walk, snowball, etc.), and spectral decomposition.

The project purpose is to develop an application to store and analyze workout data. Workout data in terms of duration of a training session, average pulse during the session and so forth. The focus will be on endurance training.

JQHull is a Brad Barber's QHull library (http://www.qhull.org) wrapped in Java.
