Open Source Java Code Generators

Jad Java decompiler plugin for Eclipse IDE.

SMC takes a state machine stored in a .sm file and generates a State pattern in 14 programming languages. Includes: default transitions, transition args, transition guards, push/pop transitions and Entry/Exit actions. See User Manual for more info.

The aim of this project is to develope a decompiler for java which is platform independent and has options to obfuscate the class file also. The project takes class file as input and decompiles it and provides the source file.

Retrotranslator is a tool that makes Java applications compatible with Java 1.4, Java 1.3 and other environments.

z390 Portable Mainframe Assembler and Emulator

BNF for Java is a BNF Compiler-Compiler, or Parser-Generator. It implements ISO Standard Backus-Naur Format, using Java. BNF allows you to create a syntax, or a complete language, to parse your data source. Your custom Java extensions generate output.

SableCC is a parser generator which generates object-oriented frameworks for building compilers, interpreters and other text parsers. SableCC keeps a clean separation between machine and user code which leads to a shorter development cycle.

openASN.1 is an Open Source Java toolkit for the Abstract Syntax Notation One (ASN.1) which consists of a compiler and codec with a low footprint runtime library.

This sourceforge site for the project is now DEPRECATED and not updated. All current work and new releases are on github: https://github.com/OpenJML/OpenJML. The Java Modeling Language (JML) is a behavioral interface specification language that can be used to specify the behavior of Java modules (as in design by contract -- DBC). It has many tools to do assertion checking, unit testing, etc. The principal current tool of the project is OpenJML -- cf. https://www.openjml.org, with binary downloads from https://github.com/OpenJML/OpenJML/releases/latest

ULS is a class library for creating lexical analyzer from language specification file. It's provided as C/C++/C# and Java (class) libraries with a few of tools on Linux/Windows platform.

jdec is a Java Decompiler. It can be used to reverse the bytecodes present in a .class File to produce a Java Source File which can be nearly correct or equivalent (Due To different Interpretations) to the original java file.[With UI & command line]

Pizza is a small, fast and free compiler for Java and an important superset of the Java programming language. It is written in Java/Pizza and compiles to Java class files.

JavaGuard is a general purpose bytecode obfuscator, designed to fit effortlessly into your regular build and testing process, providing peace of mind that your valuable Java code is more secure against decompilation and other forms of reverse engineering

JAC (Java Asn1 Compiler) is a tool for you if you want to (1)parse your asn1 file (2)create .java classes and (3)encode/decode instances of your classes. Just forget all asn1 byte streams, and take the advantage of OOP! BER, CER and DER are all supported

RECODER is a Java framework for Java program analysis and source code transformation. It computes an easy to use syntactic and semantic program model containing cross references, and it supports transformation rollbacks and incremental model updates.

Beaver is a LALR compiler compiler for Java that uses several techniques to generate very fast parsers.

JFlex is a flex-like lexer generator for Java with emphasis on speed and full Unicode support. It has some not so usual features like negation in regexps and nested input streams. Also reads JLex specifications unchanged.

JavacTo is a prototype tool designed to evaluate the need and value of translating java code into another programming language. An ideal language for translation is a language that supports the concept of packages, classes, interfaces, and enums as well as built-in memory garbage collection. Languages such as C# and D, are well suited as a translation “To” language. Eclipse project provided to get started. Three visitor classes provided to learn how to use JavacTo and write visitor classes.

XML encoder for source code

JadRetro is a Java decompiler helper supporting Java 1.5+ classes. JadRetro is not a decompiler itself, it is a class transformer helping some old (but good) Java decompilers to convert more class files and/or generate more correct source code.

This project has moved to http://github/mlhartme/mork.

Tho goal of this project is to provide an integrated development environment for developing (x)Harbour applications on various platforms.

OJ (f.a.k.a. OpenJava) is an object-oriented macro system with a compile time metaobject protocol for Java.

Chasm-interop is a set of tools that parses C++ and Fortran 90 source files and automatically generates bridging code to provide for seamless language interoperability.

HATE's an ASN.1 Text Editor written in Java. It is designed to be easy to use, highly customizable and flexible.
