Actually, there is another error as well. The code in an initializer is not
in a truly static context unless it is preceded by the "static" keyword.
Example:
public class AClass {
public static int foo;
static {
// will assign foo to 2 upon class loading
foo = 2;
}
public int bar;
{
// will assign bar to 2 for each new instance.
bar = 2;
}
}
This can make things really confusing when instantiating classes with this
kind of thing. If you're really interested I suggest creating a class (and a
superclass) with this kind of structure and then stepping through it in a
debugger.
(BTW, we're getting pretty far away from servlets at this point.)
