This project offers a simple java class to be used for any Facebook authentication needs. This class allows you to simply pass the Facebook application client id and show a login and authentication window, and returns the session token from Facebook. This is extremely useful for anyone who wishes to make a program in Java that needs to be able to have a user login and subsequently access the Facebook API to get any information about the user. Uses the DJNativeSwing library.

Java implementation of Fuzzy Cognitive Maps (FCM). Implementation aims to be: small (and fast), simple to use, flexible enough to be used as a basis for other projects / libraries.

This project provides utilities to convert a JavaFX Scene to Swing Graphics2D orders. It it then simple to use it to convert to any format which takes a Graphics2D as input. The project comes with a PowerPoint, a SVG, and an EPS converter.

JFlex is a lexical analyzer generator for Java, designed to create fast and efficient scanners. It takes regular expression specifications and produces Java code for tokenizing input text. ​

This work pursued two main objectives: - Develop a java library that allows to easily create Excel files via OLE2.0 technology, which could be used by developers regardless of the data origin. - Develop a system for JForex platform, taking advantage of the library developed, which allows End Users to easily obtain data from any instrument offered by the platform at any period, or the Ticks information of the instrument. At the same time, this system could be improved, modified and / or extended by other developers. Of the first objective, was born the OLExcel library, which lets use the OLE Compound File technology (http://msdn.microsoft.com/en-us/library/dd942557.aspx), using the Apache POI library (http://poi.apache.org). OLExcel greatly simplifies the job of creating Excel files using Java through OLE2.0 technology. Of the second objective, was born the JForex2Excel system, that making use of the OLExcel library, send data from the JForex platform to a file in Excel format.

A java library for reading command-line options and arguments.

LRU caching map is Least Recent Used Map, (see Wiki), meaning that a Key,Value pair is stored in the cache, with a "expireTime", but every time the Key is retrieved (get method) the expire time is extended. It is a simple POJO one jar library. With complete documentation with examples and javadoc. When the cache reaches is "maxSize" or a cleanup of the cache is performed (automatically by deamon thread dependent on the "LRUCachingMapConfiguration"), it is the keys with least recent used (lowest expire time) that is discarded first. This library has extended configuration, so you have the ability to set how times a keys expired time can be extended. See more about the configuration abilities at Configuration. Additionally this library has "ValueManager" interface, which wraps how the Value is stored. This can be in Memory or in a Persistent storage like File, FileReference or Database which will give ability to restore the cache.

Version 3.0 is under construction (expected release "feb/2017") * full java 1.8 support * no marker interfaces, only annotations * fully updated documentation * framework refactored * maven support, and upload on github. Version 2.0 is now available. (31-07-2015) Release notes: http://jhpropertiestyp.sourceforge.net/releasenotes.html JHPropertiesTyped will give the developer strongly typed properties. Easy to integrate in existing projects. Handled by a large series for property types. Gives the ability to one-line initialize properties via property IO implementations. Gives the developer the ability to create own property types and property io's. Web demo is also available, screenshots shown above. Also have a standard implementation for a web front end to manage properties, if you choose to use it. Complete documentation, tutorial, javadoc, faq etc is a available on the project webpage below.

N.B. THE PROJECT HAS BEEN MOVED TO GITHUB https://github.com/jiprolog/ JIProlog is a cross-platform pure Java 100% Prolog interpreter that integrates Prolog and Java languages in a very fashinating way. JIProlog is compliant with the major Prolog interpreters. It supports most of ISO Prolog specifications and the most common and used built-in predicates, JIProlog allows to call Prolog predicates from Java without dealing with native code (JNI or JNA) and allows to invoke Java methods from Prolog in the same way you call predicates.

This project aims the goal to provide a library to implement in an easy way the communication protocols between applications.

Kogonuso JLevel - a simple java library that has changed the way html can be written inside Java(tm) both application and Sevlet. It is a library that is more than your ordinary Html parser applications. It has automated all tagging operations of Html inside java, this means that you are no longer required to learn how to format html String when developing application that requires html in java or even when using Servlet technology to develop your websites. Just import JLevel 2.0 and turn all the tag elements that you have ever known into simple method call. The best is there for you to discover as JLevel not only stripped off tagging in Java html , it has formulated series of shortcuts by abstracting redundant html codes that we have often repeatedly written saving you valuable time. You will no longer dread including html as a formatting tool in your java application when you use JLevel 2.0. Another important feature that JLevel 2.0 has made possible inside java is the abilit

Various listener types.If file is changed, property present in file gets changed, to see the changes and use these changed values in your running applications.This Java API allows you to use listeners like PropertyChangeListener, FileChangeListener, etc.

Biblioteca para Java que implementa un potente evaluador matemático en español y un lenguaje estructurado de script, JMEScript, que hace uso de éste. Puede evaluar expresiones altamente complejas, que incluyen; * vectores * matrices * números complejos * números enteros y reales de precisión arbitraria, * expresiones booleanas * conjuntos * cadenas * diccionarios * grafos * correspondencias y relaciones finitas Permite especificar operaciones y funciones definidas por el usuario además de incluir más de 60 operadores predefinidos y más de 450 funciones predefinidas. También implementa un potente modo REPL que permite usar interactivamente la mayoría de características del lenguaje implementado por la biblioteca JME, incluida la importación y exportación CSV, HTML, JSON y XML.
