The 3.0 spec says the following for a session bean class:
/The class must implement the bean's business interface(s) or the
methods of the bean's business interface(s), if any./

While implementing the method in my bean class, can I use *covariant*
return type? Can I just assume Java language rules of implements? Or is
there a chance that some container may go for stricter method matching
and reject my app? I am asking this because the methods that correspond
to 2.x remote or local interface, the spec requires that return type to
be *invariant*.

Thanks,
Sahoo
