Open Source Java Frameworks

JPPF makes it easy to parallelize computationally intensive tasks and execute them on a Grid.

The purpose of the project is to develop a portable programming framework that facilitates distributed and multi-threaded programming for C++, Java, and Python. MADARA was originally developed as an agent-based middleware specifically for real-time, distributed artificial intelligence, but is now more general purpose for distributed timing, control, knowledge and reasoning, and quality-of-service. MADARA is composed of several tools and middleware, and the main entry point into the system is the Knowledge and Reasoning Language (KaRL) Engine, which provides a real-time scripting language for nanosecond execution times hooked into a flexible transport layer for distributed reasoning. The KaRL engine also supports object-oriented C++, Java, and Python programming through Containers, classes that provide abstractions and references for variable location within the KaRL Knowledge Base. This project is currently in process of being ported from http://madara.googlecode.com.

Raindrop is a Java based framework based on SEDA (Staged Event Driven Architecture) principles. It focuses on providing highly concurrent server side throughput by managing and controlling Thread usage and concurrency primitives.

QuickServer is an open source Java library/framework for quick creation of robust and multi-threaded, multi-client TCP server applications. With QuickServer one can just concentrate on just the application logic/protocol on hand.

MARF is a general cross-platform framework with a collection of algorithms for audio (voice, speech, and sound) and natural language text analysis and recognition along with sample applications (identification, NLP, etc.) of its use, implemented in Java.

Utility classes for sending files over JMS providers like ActiveMQ, use of XDoclet generated code and Hibernate in J2EE projects. In addition code to call EJB SessionBeans from C++. Programming Language: java Libraries: XDoclet, Hibernate

Aladdin is a dynamically extensible context acquisition and modeling framework designed for resource constrained mobile devices. Aladdin was created by Darren Carlson (http://dcarlson.info) and is currently being extended to support OSGi and Android.

Ambient Composite Engine, a web-based framework for writing composite software, submitted by WebactiveLabs.

Aracnis is a Java based framework for building distributed web spiders. These spiders can be used to accomplish a variety of tasks, for example, screen-scraping and link integrity checking.

Argos is a middleware system that lets you easily create and deploy software components, webpages, widgets, J2ME applications and panels and bind them together into services. Argos uses a microkernel that enables developers to extend the system functiona

Assimilator is a set of tools and services providing a self-monitoring, self-managing and self-healing environment for distributed computing.

A lightweight Framework to build remote applications.

CArtAgO is a framework for programming and executing virtual environments in multi-agent programs.

Alternative implementation of Spring framework remoting subsystem that supports different schemes of remote communication between client and server (1-1, 1-many, dynamic services discovering).

Clutch is a Java framework for distributed computing using mobile agents. Built using ProActive [http://www-sop.inria.fr/sloop/javall/], it is meant to be a scalable toolkit that can be used to distribute computation across an arbitrary number of nodes.

CoDeK - Java Concurrent Development frameworK is a very simple, open-source, academic java library aimed to help the development of Java multi-threading concurrent applications.

The CodeTime platform covers every aspect of parallel software from authoring, through distribution, to run-time. Its goals are: high programmer productivity; write once, run high performance anywhere; and wide acceptance.

Compiere MFG+SCM Manufacturing Extended System (MES). Include Shop Floor Control, Supply chain management, Quality management, modbus interface, iReport barcode extension etc. Support batch and on demand manufacturing. Works alone or connected to ERP.

Project provides a set of concurrent building blocks (Java & C/C++) that can be used to develop parallel/multi-threaded applications. Components are grouped into 4 categories: 1.Data Structures 2. Parallel Patterns 3.Parallel functions 4.Atomics and STM

The Contingency Management Framework helps design fault-tolerant, and resource-aware systems. It monitors vital resource (e.g. the network) and sets up coping strategies when different contingent states occurs. Used in Ubiquitous Computing research.

Cuckoo is an open source Resource Adapter for SAP that is compatible to the Java Connector Architecture (JCA) version 1.5. It enables developers of Java EE applications to call functions in a SAP backend, making use of Java EE features like Container Managed Transactions and Security.

DDGP is a simple grid platform written in Java. It focuses on distributed computing and data gathering in Internet environment. Intended for smaller projects requiring couple hundreds of computers gathered together for a master-worker like jobs.

Damon is a Distributed AOP Middleware on top of a p2p Overlay Network. Its main aim is to offer the necessary abstractions and services to develop distributed aspects, and to provide scalability to existent or new applications transparently.

An extensible framework to provide data adaptation services in distributed systems and ETL applications. Used to preprocess (non-XML) data into XML, transform and validate XML data and write it to a sink interface. Also includes simple XML tools.

An architecture description language (DiaSpec) supports the description of components of a given distributed computing area. From these descriptions, DiaGen generates a dedicated programming framework to support distributed application development.
