I am writing some classes that comply with java bean contract soI must
supply default constructor.
But *my* code should never call this constructor. Is it possible to make
the compiler warn me if I inadvertantly call it?

You could put a "@deprecated" javadoc comment in front of it. For example:

/**
* Default constructor.
* @deprecated Do not use it!
*/
public MyBean() {
}

I wonder if any automatic use of beans would object to that?
Not that it will affect my case - just passing to JSP pages, and they don't
write beans.

Are you allowed to make it private? I guess beans need it for their
own XML-based serialization scheme.
