public URLClassPath(String host, int port, String directory, String packageName)
This search path is used only if a requested
class name starts with the name specified by packageName.
If packageName is "org.javassist." and a requested class is
"org.javassist.test.Main", then the given URL is used for loading that class.
The URLClassPath obtains a class file from:
http://www.javassist.org:80/java/classes/org/javassist/test/Main.class
Here, we assume that host is "www.javassist.org",
port is 80, and directory is "/java/classes/".
If packageName is null, the URL is used
for loading any class.
