[jboss-user] [JBoss Seam] - Exception thrown on seam-booking-icefaces

[gus888]

Hi,

I deployed seam-booking-icefaces from CVS-20061202(icefaces1.5.1), but when I run it I often got the following exceptions. I really don't know what is the reason, since I run the original example code. Thank you very much in advance.
