Open Source Java Cross Compilers

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.

PEARL is a high level procedural programming language, which was especially designed for the demanding need to have an expressive and comfortable language for solving multitasking problems when controlling technincal processes. PEARL is an abbreviation for "(P)rocess and (E)xperiment (A)utomation (R)ealtime (L)anguage". It was designed around 1975 at the IRT Institute of the Leibniz University in Hannover with the idea in mind to have an easy to learn programming language for realtime problems. For more, also historical information please visit (http://www.pearl90.de/). In 1998 PEARL-90 was standardized by the Deutsches Institut für Normung e.V. in DIN 66253-2. PEARL provides the standard data types and structures known from other procedural languages like e.g. PASCAL. Additionally PEARL brings special language constructs for managing real-time and multitasking tasks.

Open source mini Python compiler written in Java using Sablecc as parser generator.

This project aims to provide a Java-Bytecode compiler for the fairly new programming language WRL and others like PHP4 and Postfix, based on the research on the SableCC parser generator and common W3C.ORG standards.

JaCIL (pronounced "jackal") is a project to create a byte-code compiler to translate .NET assemblies to Java class files.

RES is a pure Java based Open Source Cobol to Java translator. It creates maintainable Java code for a subset of VS Cobol syntax. It has been developed with JDK, JTB and Javacc.

The Universal COBOL Compiler (UCC) is a Java-based COBOL to Java bytecode cross-compiler. It's made up of a COBOL compiler, a Java-based COBOL runtime, and a package for manipulating Java class files.
