Well, I am happy some trolls just left the forum, they were major source of noise. I think it got down to a much more acceptable level now, and should remain so until they come back.BTW, why haven't anyone commented on Tue, 12 Jul 2005 22:25:00 -0400 Tue, 12 Jul 2005 22:25:00 -0400 Tue, 12 Jul 2005 22:25:00 -0400 Jul 12, 2005 Trevor S 0 Mats Henricson on "State of the Art" for Java, EE http://www.theserverside.com/discussions/thread.tss?thread_id=35074
