What error is it giving?
If obj.getShape actually is returning an object with a getRadius method,
the code should work as written. If obj.getShape doesn't return an
object with a getRadius method, it will end up calling the
method_missing method, which by default throws an error. I think, anyway...
If you're trying to invoke the Java code from ruby, remember that Jruby
translates to ruby-like method names, so you might try invoking those.
The old names should still work, though. See

Hi
Java code
Shape s1= obj.getShape();
s1.draw();
Circle c1 = (Circle)obj.getShape();
c1.getRadius();
It's equivalent ruby code
s1 = obj.getShape
s1.draw
c1 = obj.getShape
c1.getRadius
Now here i cannot use the type cast as i have used in java so not able to
invoke the methods of class circle. How to invoke it in ruby.? The code in
bold is giving error.
