Bytecode Worm (Java disassembler)

Home | Project page | News | Download | FAQ

Bytecode Worm is a C++ program that disassembles Java class files, directories of Java class files, or JARs with Java class files. The program is freely available under the GNU GPL.

The disassembler reads Java class files and produces something similar to the original Java source file with JVM instructions instead of Java sources.

Installation

Download the binary.zip archive of the latest version (see Download page) and unpack it. You will get bcw.exe. That's all.

Usage

To disassemble a single class file: bcw.exe {your_class_file}.class {output_directory}

To disassemble a directory of class file (including all its subdirectories): bcw.exe {input_directory} {output_directory}

To disassemble a JAR archive: bcw.exe {your_archive}.jar {output_directory}

The program will write the disassembled files into the specifying {output directory}. If the input directory or the input JAR contain files other than Java class files then the program just copies those files into the new location.

Limitations

The only know limitation: the program doesn't parse generics. In the output the generic types are presented by the result of their descriptors parsing (i. e. as in Java prior to 1.5).
