      Hi,

      We have been facing an exception for some time now where an exception is raised at the time of login if the application is left idle for a few hours. This especially happens if the JBoss AS 3.2.7 is left running over night. The next day, on login attempt the following exception is raised

      Caused by: javax.faces.FacesException: #{index.validateUser}: javax.faces.el.EvaluationException: java.lang.NullPointerException

      We have not been able to narrow down the root cause of this problem. I am also not sure of the exact time period which causes problem.

      I will appreciate if someone can help me find a solution to this.

      Thanks in advance.

      regards,

      Sultan
