Method Detail

public java.lang.Class loadClass(java.lang.String name,

                          throws java.lang.ClassNotFoundException
This modification allows us to reload classes which are in the Java VM user classpath. We search first rather than delegate to the parent classloader (or bootstrap path) first.

Overrides:
loadClass in class java.lang.ClassLoader
java.lang.ClassNotFoundException

findClass

protected java.lang.Class findClass(java.lang.String name)
                             throws java.lang.ClassNotFoundException
Find the correct source for the class... Try designated loader if any Try our URLClassLoader paths if any Try base loader if any Try system ???

Overrides:
findClass in class java.net.URLClassLoader
