loadClass
public Class loadClass(String name, boolean resolve) throws 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. An exception is for BeanShell core classes which are always loaded from the same classloader as the interpreter.- Overrides:
loadClassin classClassLoader- Throws:
ClassNotFoundException
-
findClass
protected Class findClass(String name) throws 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:
