[aspectwerkz-user] Hot deploy in a specified classloader

hi guys,
this is my problem:
i use an URLClassLoader to load and execute an application at runtime.
during the application's execution i want to deploy an Aspect to dinamically
change its behaviour.
I am actually using this method

public static DeploymentHandle deploy(Class aspect, String xmlDef,
ClassLoader deployLoader)

where deployLoader is the instance of the URLClassLoader that i have used
...
nothing happens...

can you help me?

Thanks in advance

Andrea
