At the moment yes, because of limitations of the java.lang.reflect.Proxy
class.
Generating mocks that extend real classes causes a number of tricky issues.
For example, what should mocks pass as arguments to constructors of the base
class? What if the constructor of the base class does "real" work, that you
don't want to happen at test time?
Automatically generating an interface from a class would not work because
the mock must be interchangeable with the class to be mocked at compile
time.
So, if you want to mock an existing class I would recommend changing the
design of that class so that it follows interface/implementation separation
and then using the dynamic mocks. If you don't want to do that, you can
write a mock by hand using the core com.mockobjects classes.

There are also the unit tests in the test.mockobjects.dynamic package. On
the wiki, you can also read:
