Apache Byte Code Engineering Library

Apache Byte Code Engineering Library (formerly known as JavaClass) is intended to give users a convenient utility to analyze, create, and manipulate (binary) Java class. Classes are represented by objects which contain all the symbolic information of the given class, in particular the methods, fields and byte code instructions. Such objects can be read from an existing file, be transformed by a program (e.g. a class loader at run-time), and can be dumped to a file. One interesting application is the creation of classes from scratch at run-time. Apache Byte Code Engineering Library (BCEL) may be also useful if you want to learn about the Java Virtual Machine (JVM) and the format of Java .class files.
