NULL POINTER EXCEPTION!
I was trying to create a handler for the web service above.
It should be the equivalent of (Java):
public class Calculator {
public int add(int i1, int i2) {
return i1 + i2;
}
public int subtract(int i1, int i2) {
return i1 - i2;
}
}
So I basically wrote the following:
(def Calculator
(proxy [] []
(add [x y] (+ x y))
(subtract [x y] (- x y))))
But I get the following error:
java.lang.NullPointerException
Anybody have a clue?
