...And I believe it was on this board (IE, not the old IWT), but I'm not 100% sure on that.
Anyway, my recommendation for a great Swing reference is "Java Swing" by Eckstein, Loy, and Wood. O'Reilly publishing.
And stay far, far away from "Graphic Java, Mastering the JFC" by Geary.
Of course, your Java library is not complete without O'Reilly's Java in a Nutshell. EXCELLENT reference book. Most of the information in there can be found online (either Sun's website or through your IDE's help)...But if you prefer having a hard-copy in front of you (as I do) then it's invaluable.
