Open Source Java Frameworks

IKVM.NET is a JVM for the Microsoft .NET Framework and Mono. It can both dynamically run Java classes and can be used to convert Java jars into .NET assemblies. It also includes a port of the OpenJDK class libraries to .NET.

A programming language AL-IV (ALFOUR) is a high-level imperative object oriented programming language with minimal introduction level, easy porting to any platform claiming a very high level of safety and stability, with a controllable level of code protection, high efficiency of an executable code, full independence from a target platform, minimal enter level.

JTools provides some useful tools and utilities for Java 5.0 development. Beneath some smaller utilities we have: a (Ant like) DAO framework (also including XML Repository) and a (JSP like) general purpose template generator and execution framework.

The Ja.NET project provides open source Java development tools (e.g. Java 5 JDK ) and runtimes for .NET. With the help of Ja.NET's open source software, you can leverage your Java investments on .NET.

The Lagniappe programming environment aims to give developers of high-performance packet processing applications a thourough and high-level toolset. This project provides a translator for the Lagniappe language and the Lagniappe Execution Environment.

This is the implementation of the AspectJ plugin for NetBeans 6.0 and higher.

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.

Metaprogramming: proof of the concept.

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.

Fan is an OO, functional programming language designed to cross compile to both the Java and .NET platforms. It provides a concise syntax along with elegant, cross portable libraries. http://www.fandev.org/

The Generic Analyzer is a framework in Java that is designed to allow users to build, quickly and easily, compilers and interpreters without the need to implement all the complex steps of a translator.

J2c is the J2 language compiler, a superset of the Java language. The compiler can produce code for the Java and .NET platforms.

JAXX is a powerful XML user interface language for Java. JAXX source files compile into ordinary Java classes, making integration a snap. JAXX features advanced data binding and event handling, and uses (fully compiled) Java as its scripting language

JDotNet tries to reimplement the .NET Framework partly in Java to improve the compatibility between Java and .NET. There are also plans for a compiler which may translate .NET to Java code.

A Java Library for parsing and evalutaing Mathematical expressions, that can deal with Numeric, Dates, Text and Boolean values, and can detect circular references. You can also create your own functions, rename existing functions to your language

JUndo is a declarative object-oriented programming language with functional, and intensional programming characteristics. Applications include multi-level undo and sophisticated error recovery. See http://verdantium.blogspot.com/

Runtime library for the JUndo language. See http://verdantium.blogspot.com/

Jabaco is a simple Visual Basic like programming language for the Java Virtual Machine. A comfortable development environment will support you in your tasks. Visit the Webcast and see Jabaco in action: http://www.jabaco.org/webcast.html

JAva Compiled EXpressions - Very fast exression engine for Java, compiled into Java bytecode. Features: - Strong typing - Comipilng into Java bytecode - No reflection during evaluating expressions - Better performance for prepared expressions

Object Mapping Project (OMaP) proposes a way to define and to perform mappings of Java object instances. The objects could be mapped to a XML String, another Java object, database records, Swing screens, etc. And, of course, mapping back is also supported

Component that visualizes and it prints documents based on JPanel, besides creating reports in a fast and efficient way using the own IDE. Not being necessary the use of software of third, to create the reports.

The Java/RTR Project address the development of soft real-time code in Java, mainly using the RTR Model and the Java/RTR programming language. It uses the RTSJ specification as main API, and only works on plataforms that have support to it.

The project implement a framework of modular compilers that allows compile time programming for .NET, Java and other platforms. Languages on this framework are multi-paradigm and can be extended by programming new semantic structures or DSL.

Description language based on XSD and rules stored in a centralized directory intend to allow development of applications from static descriptions.

OpenL implements Java-like languages allowing to use code snippets placed in Excel, XML, or DB. OpenL is a foundation for OpenRules http://openrules.com. Maintained from http://openl.org
