An authorization library that supports access control models like ACL, RBAC, ABAC for Golang, Java, C/C++, Node.js, Javascript, PHP, Laravel, Python, .NET (C#), Delphi, Rust, Ruby, Swift (Objective-C), Lua (OpenResty), Dart (Flutter) and Elixir. In Casbin, an access control model is abstracted into a CONF file based on the PERM metamodel (Policy, Effect, Request, Matchers). So switching or upgrading the authorization mechanism for a project is just as simple as modifying a configuration. Besides memory and file, Casbin policy can be stored into lots of places. Currently, dozens of databases are supported, from MySQL, Postgres, Oracle to MongoDB, Redis, Cassandra, AWS S3. jCasbin is a powerful and efficient open-source access control library for Java projects. It provides support for enforcing authorization based on various access control models.

This is a library for parsing command line arguments passed into the java code.

jFAN2 project develops a Java API to use a neural network (neuro-fuzzy) called FAN (Free Associative Neurons). Its an reprogramed version of jFAN "https://sourceforge.net/projects/jfan/".

jFuzzyDate is a lightweight java library for formatting easily readable time distances, durations and dates.

jHermes is an asynchronous communication framework for Java. In the spirit of Apache MINA, this is meant to provide a high-level abstraction for applications to utilize efficient asynchronous communication.

The Project jICPBr is an API for Brazilian Digital Certificate

jInterflex is a Java open source library that invokes methods and reads public fields of classes through reflection in a different way, using annotations and interfaces. jInterflex allows to specify the methods to be invoked and the public fields to be read in auxiliary interfaces, with the same signature that they actually have (or very similar), so the signatures of methods can be copied almost directly from the Javadocs of their original classes. With the help of this interfaces, the access to the methods and constants looks like the "normal" (without reflection) invokation or read access, enhancing the readability.

jLightning is a Java NIO networking library. This project has been moved into the jeuron project. Please refer to www.jeuron.org for more detail.

This Library for Java shall enable developers to use (at first read, maybe later writer) MDF Files, as described by the Format Specification MDF Format by Vector Informatics. The MDF file format is widely used in automotive engineering and other fields for the recording of measurement data. This Java library parses MDF files and enables different kind of read access. If this library is not helpful for a particular purpose it can at least be used to see how the parsing (and therefore how the file format itself) works.

This simple project provides a way to efficiently calculate the actual memory use of any Java object. The class makes use of the JVMs own instrumentation support to calculate the object memory use in a portable way.

A Java implementation of a NAT-PMP client. At the project's inception, there was not a well-known NAT-PMP client library for Java. This project intends to fill the gap.

jProwlAPI is a library to provide access to the API of the Prowl-Service (http://prowl.weks.net/). Prowl is a service that lets you push notifications directly to your iPhone.

jSql provides feature to filter the java collection using SQL similar syntax. Currently <,>,>=,<=,= ,and,or operators are supported, soon in,like,between and order by will be supported.

jStyleParser is a CSS parser written in Java. It has its own application interface that is designed to allow an efficient CSS processing in Java and mapping the values to the Java data types. It is also able to apply the parsed style sheets to a DOM that represents an HTML or XML document and to compute the resulting style of the individual document elements. It supports CSS 2.1 and a large subset of CSS3.

jUpdateChecker is a Java library providing your application with an easy update checking method.

A framework that allows to create parsers and formatters for any type of text files easily in java. The parsing result is stored in java beans.

This project is Java 1.5 port of the JArgs Project (http://jargs.sourceforge.net) with minor changes like validation and the annotation-based configuration for command-line options.
