I solved it. Sorry for bothering with environment questions.
. First of all I changed to Sun's VM, invoking Tomcat 4.0.1 with it. . I added the classpath of my own Cocoon Components into the web.xml of Cocoon, on the <init-param> named extra-classpath . And I needed to set the <init-param> named init-classloader on the same web.xml to true, for cocoon to use his own classloader.

Yes, it is instance of *this* particular instance of the Component class, but *not* the instance of the Component class loaded by Cocoon. You have got *two* instances of the Component class. Avoid instantiating of the action outside of Cocoon, or do it using Cocoon's class loader.

I don't quietly understand that, doesn't Cocoon > use the Java ClassLoader of the virtual machine running it? Java might have more then one *instance* of class loader. Even *same* class file loaded by two different instances of the class loader is *different*. Try System.getIdentityHashcode() on your Component.getClass() and Cocoon's Component.getClass() - this will be two *different* classes. > I see a > components.classloader package in cocoon, that's the class loader it > uses?
