## Class JavaWrapper

- java.lang.Object
- - org.apache.bcel.util.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]
