|
|
* The required files are:
|
|
*
|
|
* - Loader.java (a 1.1 style class loader)
|
|
* - Loadee.java (source for a class that refers to Loader)
|
|
* - Loadee.classfile (to test findSystemClass)
|
|
* - Loadee.resource (to test getSystemResource)
|
|
*
|
|
* The extension ".classfile" is so the class file is not seen by any loader
|
|
* other than Loader. If you need to make any changes you will have to
|
|
* compile Loadee.java and rename Loadee.class to Loadee.classfile.
