Open Source Java Libraries

ThreeTen provides a modern date and time library for Java and is the reference implementation for JSR-310. It includes many of the lessons of the Joda-Time project and aims to standardise date and time concepts in computing. Code now integrated into OpenJDK, this project is archived.

Hex-Lib GUI takes the library HexLib into action, i.e. it is a working, fully functional Hex-Editor on base of HexLib. This project demonstrate the usage of the library for Java developers interested in the library in a practical approach.

The goal: to provide implementations of as many algorithms (sorting, searching, ...) and data structures (lists, trees, ...) as possible, accompanied by discussion of big O run time and memory limits and references to sources of further study.

This project provides libraries and tools for Android, starting with an endless list implementation and support for easy integration of Apache Solr data into an endless list. An additional library will be an Android forms library for easy and consistent form creation for business apps.

CouchDB4CF is a set of ColdFusion facade objects that encapsulate the easy to use CouchDB4J project written by Marcus R. Breese (http://github.com/mbreese/couchdb4j). This project's purpose is to simplify access to CouchDB databases.

A graph persistence framework and associated toolkits based on a navigational query style. A default persistence engine is included for storing graph objects and properties into simple relational tables but the actual storage model is pluggable.

A Java component which displays bytes in Hex- and ASCII-format. The component is designed as a standalone lib. A complete interface which provides the function of an HexEditor based on this lib exisits under the Fork of this project.

An easy way for checking the precondition(s) of (public) methods and constructors (design by contract). All arguments can be checked, before an IllegalArgumentException is thrown. Creating consistent messages for inconveniences in argument values.

DSA extensions contains classes similar in purpose to the classes provided in java.util. Currently, it contains sortable Lists and Maps, as well as a balanced binary search tree and a binary array search algorithm.

A Java library for creation and editing of several playlist formats.

API Java de visualisation et d'interaction dans le domaine des graphes.

This is a java native wrapper, based on JNA of standard methods to access smart cards (pkcs11, pc/sc, openct, libusb). Goals of this projects are: * interoperability: it can work on any platform where JNA runs: Windows, Linux, Mac (and one day even Android) * modularity: you don't need to include pc/sc support if you only use pkcs11 * ease of integration: it depends only on few required libraries. * ease of use: it exposes a simple java interface (even if you can deal with the JNA classes directly)

This library contains utility classes such as a converter from plain text to HTML (for safe inclusion of user-supplied text into web pages, avoiding XSS attacks, etc.), converters from binary to hex representation, and similar functions

The QcTools4j project consists of an API for manipulating Quality Center software within Java.

A base set of libraries. Boilerplate type code and algorithms. Currently skuttil (Java util & parsing code) and searKit (generic Java search framework).

For Java developpers who need to request SOAP server... until SOAP is deprecated. This is a client Java API. It does not require neither perform any code generation. It fits within a single jar file. soap-dust is validated against real servers.
