Open Source Java Interpreters

Community Z Tools Project (CZT): Tools for editing, typechecking and animating Z specifications and related notations. Includes a Java framework for building formal methods tools. NOTE: development of CZT has now moved to GitHub: https://github.com/community-z-users/czt

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.

JPype is an effort to allow python programs full access to java class libraries. This is achieved not through re-implementing Python, as Jython/JPython has done, but rather through interfacing at the native level in both Virtual Machines. Maintenance and evolution of the project has moved! please see http://www.jpype.org for the latest version

The only -complete- XUL/embedded scripting solution for Java. JFCML supports not only AWT and Swing; but any class accessible to Java's ClassLoader. Also, most major scripting languages, including JavaScript, BeanShell, Jython, Jacl (Tcl), JRuby, more.

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

Compose* is a project that aims at enhancing the modularization capabilities of component- and object-based programming. In particular, Compose* offers aspect-oriented programming through the composition filters model.

A Controlled Language Programming (CLP) compiler, runtime engine, and development IDE for writing software in a natural (but somewhat restricted) language that clearly represents the real world concerns and maps to a 3GL (Java/Groovy) for execution.

Metaprogramming: proof of the concept.

From the XML definition of your database, DewDrop will generate clean and human-readable SQL DDL code for any supported target database. This means you can define your database just once in XML, and have it work for any database automatically.

Extensible language for portable parallelism. Any visual element may be used to extend program syntax and a re-writing rule defined for it. Syntactic elements have properties attached, enabling symbolic manipulation to specialize to hardware.

EsoTransformer is a kind of a translator which translates esoteric languages like Brainfuck into more common programming languages as Java or C++.

The Frame Processing Language (FPL) is an XML language based on the Frame Technology by Paul G. Bassett as described in his book “Framing Software Reuse: lessons from the real world”. FPL is implemented in Java using JDOM,Saxon and Jakarta-oro.

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.

JC is a Java virtual machine implementation that converts class files into C source files using the Soot Java bytecode analysis framework, compiles them with GCC, and loads them using a built-in ELF object loader. JC uses GNU Classpath's class library.

A command line parser for Java programs generated from a XML file via XSLT.

JFolder is a web-based application development and management tool. It allows users to create applications through a web browser without writing any code. The current release includes an implementation of the Pet Store written without code.

Janux is a project to port the java virtual machine directly on top of the Linux kernel using bypassing the traditional posix enviroment. This results in very fast java implementation for linux and and opportinuty to develop java based operating syste

Java-program to read, modify and execute class-files. a real java VM written in java or a decompiler for class-files is possible (and partially working)

Java Web Application Framework. Write good-looking, styled, hacker-proof, well-behaving, customizable, content-rich Java web applications easy in a minimum time using designers & framework services.

Jxp is a template engine/script processor that processes scripts containing jsp-like code to produce text output. The script syntax is like jsp (without taglib) except that it is much simpler and can be used outside of webcontainer.

lightJacc is a small but strong grammar parser generator. It adopts a parsing strategy of its own: dynamic concurrent parsing -- which made it much stronger than LR or LL family CCs (YACC, ANTLR, etc), but still keep good performance.

MiniLang is yet another scripting language written in Java programming language. Main features : Functional language, Strongly interact with Java, XML integration, Statickly typed, Integrated template engine like Velocity or Smarty...

Powerful PHP IDE/Editor. Automatically generates code for your scripts, based on our own PHP Framework. Can create projects, full class/function breakdown. Supports PHP 5x. Under active alpha development (as of Feb 06), subversion repository for latest.

ParGeL is an LALR(k) parser generator, which allows creation of inheritable parsers in runtime and compile time environments. ParGeL is written 100% in Java.

Native Java parser framework, no (pre-)compilers needed. Closely follows BNF syntax. Optimized for performance and low overhead. Highly flexible and extendable using a streamlined API. Integrate semantics, tracing and even context sensitive parsers.
