I'm trying to take a String with the name of a class, and instantiate
objects of that class. I've been trying to do this with Class methods:
Class class_type;
class_type = Class.forName("class_name");
...
Object obj;
obj = class_type.newInstance();
This compiles OK, but running it gives a "java.lang.NoSuchMethodError" on
that last line. And even if it did run, I'm not sure what to do with the
resulting object -- how do I call a constructor for obj?
Is there another way to do this? Am I not _supposed_ to be able to do this?
thanks,
gregg
