BSFManager.setClassLoader doesn't seem to work

[Sonny To]

Hi,

I am trying to use URLClassLoader with BSFManager so that it loads
classes from my webserver.  The following code does not seem to work:

package net.omnivention.bsf;

import java.net.URL;
import java.net.URLClassLoader;

import org.apache.bsf.BSFManager;
import org.python.core.PySystemState;

public class WuluClassLoaderTest {

        public static void main(String[] args) throws Exception {
                BSFManager.registerScriptingEngine("ruby",
"org.jruby.javasupport.bsf.JRubyEngine", new String[] { "rb" });
                BSFManager manager = new BSFManager();
                manager.loadScriptingEngine("ruby");
                manager.loadScriptingEngine("jython");                
                URLClassLoader clzLoader = new URLClassLoader(new URL[]{ new
URL("http://linuxjedi.omnivention.net/~son/";) });
                
                Class<?> clz = 
clzLoader.loadClass("cn.com.blackdragonmedia.Address");
                System.out.println("clz="+clz);
                manager.setClassLoader(clzLoader);
                System.out.println(manager.getClassLoader());

                PySystemState.add_package("cn.com.blackdragonmedia");
                manager.exec("jython", "abc", 0, 0, "from 
cn.com.blackdragonmedia
import Address");
                manager.exec("ruby", "abc", 0, 0, "include_class
cn.com.blackdragonmedia.Address'");
        }
}
URLClassLoader is loading the class when using
clzLoader.loadClass("cn.com.blackdragonmedia.Address")
but not when I run the python script and ruby script to import the class

for python, I get
Exception in thread "main" org.apache.bsf.BSFException: exception from Jython:
Traceback (innermost last):
 File "<string>", line 1, in ?
ImportError: cannot import name Address

        at 
net.omnivention.bsf.WuluClassLoaderTest.main(WuluClassLoaderTest.java:24)

for ruby, I get

Exception in thread "main" org.apache.bsf.BSFException: Exception
        at org.jruby.javasupport.bsf.JRubyEngine.exec(JRubyEngine.java:110)
        at org.apache.bsf.BSFManager$6.run(BSFManager.java:493)

        at 
net.omnivention.bsf.WuluClassLoaderTest.main(WuluClassLoaderTest.java:25)

Any idea how to BSF to use URLClassLoader?
