I agree with you...

You cannot cast an object just by having a class name in a string. So you have to use the class as
B bb = ( B ) Factory.create ( "B" ) ;
Just to simplify coding you can create static methods like createB ( ), createC ( ) which will return a reference of object of class B and C respectively and from within those methods call your original create ( "Classname" ) method , typecast the returned object to appropriate type and return it. This way you don't have to type cast the objects everytime you call create() and you can use

B bb = Factory.createB ( ) ;

I agree with you that Reflection is missing the functionality you have mentioned in your query.
