Jad Java decompiler plugin for Eclipse IDE.

ProGuard has moved to Github now: https://github.com/Guardsquare/proguard ProGuard is a free Java class file shrinker, optimizer, obfuscator, and preverifier. It detects and removes unused classes, fields, methods, and attributes. It optimizes bytecode and removes unused instructions. It renames the remaining classes, fields, and methods using short meaningless names. ProGuard is useful for making code more compact and more efficient, on the desktop, on tablets, on smartphones, and on embedded devices. It also makes code more difficult to reverse engineer.

This project aims to be the best, clearest library for generating QR Codes. My primary goals are flexible options and absolute correctness. The secondary goals are compact implementation size and good documentation comments. This work is an independent implementation based on reading the official ISO specification documents. I believe that my library has a more intuitive API and shorter code length than competing libraries out there. The library is designed first in Java and then ported to TypeScript, Python, Rust, C++, and C. It is open source under the MIT License. For each language, the codebase is roughly 1000 lines of code and has no dependencies other than the respective language’s standard library.

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 Whole Platform is a technology for engineering the production of software. We provide an Eclipse based Language Workbench for developing, manipulating and transforming languages using a model driven approach.

SQL DAL Maker is a generator of DTO, Model, and DAO classes to access relational databases. Target programming languages: PHP, Java, C++, Python, and Go. To generate the class, you declare it in XML meta-program. At the stage of code generation, the target database must exist and be available for JDBC connection. Generated code is being synchronized with the current database schema using "live" JDBC metadata. Written in Java. Implemented as plug-ins For Eclipse: https://marketplace.eclipse.org/content/sql-dal-maker For IntelliJ: https://plugins.jetbrains.com/plugin/7092 HOWTO install-update: http://sqldalmaker.sourceforge.net GitHub: https://github.com/panedrone/sqldalmaker Quick-Demo in mp4: https://github.com/panedrone/sqldalmaker/releases/tag/latest

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.

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

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

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.

XDoclet is an extended Javadoc Doclet engine. It's a generic Java tool that lets you create custom Javadoc @tags and based on those @tags generate source code or other files (such as xml-ish deployment descriptors) using a template engine it provides.

Druid is a GUI tool for database build and management. Users can add/change/delete DB objects (tables, fields, etc). Druid generates for you: SQL scripts, docs in XHTML, PDF, DocBook, etc; code in C, C++ & Java Beans even for JDO and support Castor & OJB

Dedexer is a disassembler tool for Android DEX files. The purpose is to create Jasmin-like source files from DEX files.

z390 Portable Mainframe Assembler and Emulator

Command-line/Ant-task/embeddable text file preprocessor. Macros, flow control, expressions. Recursive directory processing. Extensible in Java to display data from any data sources (as database). Can generate complete homepages (tree of HTML-s, images, etc.)

A Java 3D graphics tool that can be used to implement graphics applications for various purposes. Provides the user interface in which a three-dimensional objects can be manipulated with ease. The application also allows you to generate code from the scene in the Java language automatically, so that objects can be created and used to run graphical applications later.

cglib has moved to https://github.com/cglib/cglib

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]

The JavaCC Eclipse Plugin provides a JavaCC & JTB editor and a builder which process .jj, .jjt & .jtb files and integrate with Eclipse's incremental build system. Compatible with Eclipse 4.6.0+ and Java 1.8+. Also embeds JTB 1.5.1.

Middlegen is a free general-purpose database-driven code generation engine based on JDBC, Velocity, Ant and XDoclet. If you already have a database, you can use Middlegen to generate EJB (CMP 2.0), Hibernate, JDO and JSP/Struts source code.

XLStoXML is a portable cross-platform desktop application for file format translation between XLS/XLSX and XML. No installation required except Java. The simple and intuitive interface allows you to do complex operations with just a few clicks. We are currently offering only a free version of this software, this means that all the features are available for you! The downloads and old versions code are distributed in SourceForge, and will be available soon. This piece of software is more than a simple converter. XLStoXML allows you to configure the translation in a wide range of combinations to reach out your requirements. Convert one or a bunch of files in short time. What else? Track your conversions in the console tab, see the errors or the success of each of the excel files. If you get stuck or you need support, we give you help in numerous ways: http://xlstoxml.sourceforge.net/#Support.
