Hi there,

I am using jboss-4.2.3.GA and seam 2.0.2.SP1 under Ubuntu Hardy with java version 1.6. I run ant deploy in the seam-booking example, and works fine. The problem is that after a period of inactivity i get the following exception in the console:

14:40:35,901 WARN  [Component] Exception calling stateful session bean default @Remove method: hotelSearch

Is this a known problem?
