Class JavaWrapper


  • public class JavaWrapper
    extends 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.

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