Sounds like the CL you create delegates to the Ant CL, thus your problem. Create your own CL by making it delegate to the Root/Bootstrap CL (by setting the parent loader to null), and the classes will always be loaded from your classes (may duplicate-load the some classes Ant loaded in its CL, but seems alright for you).
I'm no class loading expert, but at first glance this should work. --DD > -----Original Message----- > From: Upayavira [mailto:[EMAIL PROTECTED] > Sent: Thursday, October 09, 2003 2:39 PM > To: [EMAIL PROTECTED] > Subject: Preventing Parent Classloading > > I'm working on a CocoonTask.
