In Java, interfaces have *only* method signatures. What you're trying to do
looks like an abstract class, although an abstract class of this type has
limited usefulness.
What you probably REALLY want to do (note the "probably" -- what you REALLY
want to do is REALLY up to you and you only, REALLY) is define a parent
class, containing a set of common methods, marked as abstract. Then all
classes that need those methods would extend that class, and you'd have your
printError() method automatically.
Incidentally, printError() is probably done a lot better by libraries such
as log4j ( http://jakarta.apache.org/log4j/ ) and other similar creations.
I'm still trying to find the relevance to JSP in your post, and I imagine
I'll fail now, tomorrow, and the day aft... oh, heck, I'll just go ahead and
give up with that now.
