Class JavaWrapper


public class JavaWrapper
extends java.lang.Object

Java interpreter replacement, i.e., wrapper that uses its own ClassLoader to modify/generate classes as they're requested. You can take this as a template for your own applications.
Call this wrapper with
java org.apache.bcel.util.JavaWrapper <real.class.name> [arguments]

To use your own class loader you can set the "bcel.classloader" system property which defaults to "org.apache.bcel.util.ClassLoader", e.g., with

java org.apache.bcel.util.JavaWrapper -Dbcel.classloader=foo.MyLoader <real.class.name> [arguments]
