Create a ADF component by Class.forName (11g)

Question

Hello,
I'm loading a list of components by an XML, and I'd like to create an istance by Class.forName, for example:
UIComponent componet = (UIComponent)Class.forName("oracle.adf.view.rich.component.rich.input.RichInputText").newInstance();
but the system give me this error:
java.lang.ClassNotFoundException: oracle.adf.view.rich.component.rich.input.RichInputText
In the class there is the import RichInputText of and in the same class this works:
oracle.adf.view.rich.component.rich.input.RichInputText title = new RichInputText();
Any idea?
Thank you,
Cristian

Hi,
If I create my component extending Container, clients could think it's a Container (but in fact, I only used the Container feature to layout the component).
For instance, if a API client call myCustom.add(aWidget), it will break the layout of my custom component.
I can tell in the javadoc that this component must not be used as a container.
But there are other situations when a client can inadvertantly think it's a container.
Imagine that you write a method addTreeListener() that recursively register a listener to all components of a container. I don't want the Canvas and Scrollbar of my custom component to call back the listeners, but I want to hide my custom component to hide its internal and call back the listeners.
As I said, it's mainly a design question, but I wanted to improve my custom component...
