This is jikes, a java source to byte-code compiler. The compiler has been made available by IBM under their open-source license, please see: for details. To operate, the CLASSPATH environment variable must typically be set to a colon-delimited list of source directories, class directories, or zip files. Note that jikes will complain if a non-existant directory or file is specified in CLASSPATH. =============== // This software is subject to the terms of the IBM Jikes Compiler Open" // Source License Agreement available at the following URL:" // http://www.ibm.com/research/jikes." // Copyright (C) 1996, 1998, International Business Machines Corporation" // and others.

JODE is a java package containing a decompiler and an optimizer for java. This package is freely available under the GNU GPL. The bytecode package and the core decompiler is now under GNU Lesser General Public License, so you can integrate it in your project. Can be used from command line or through the Swing-based GUI. The decompiler reads in class files and produces something similar to the original java file. Jode has support for all constructs of JDK-1.3 including inner and anonymous classes. The optimizer transforms class files in various ways with can be controlled by a script file. It supports the following operations: . Renaming class, method, field and local names to shorter, obfuscated, or unique names or according to a given translation table . Removing debugging information . Removing dead code (classes, fields, methods) and constant fields . Optimizing local variable allocation

ProGuard is a free Java class file shrinker, optimizer, and obfuscator. It can detect and remove unused classes, fields, methods, and attributes. It can then optimize bytecode and remove unused instructions. Finally, it can rename the remaining classes, fields, and methods using short meaningless names. The resulting jars are smaller and harder to reverse-engineer.

VisualVM is a visual tool integrating several commandline JDK tools and lightweight profiling capabilities. Designed for both production and development time use, it further enhances the capability of monitoring and performance analysis for the Java SE platform.

ServingXML is an open source, Apache 2.0 licensed, framework for flat/XML data transformations. It defines an extensible markup vocabulary for expressing flat-XML, XML-flat, flat-flat, and XML-XML processing in pipelines. ServingXML comes with a console app, and also documents an API for embedding the software in a standard Java or J2EE application.
