Apache Commons BCEL 6.8.2 · org.apache.bcel.util.JavaWrapper

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.

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