    NullPointerException in SeamListener

    Gerald Quintana Newbie

      Hello,

      I am trying to put up my first Seam application. I didn't follow the step by the step guide mentioned in this forum (I didn't know it's existence when I started).

      When my application is deployed in JBoss I get

      Exception sending context initialized event to listener instance of class org.jboss.seam.servlet.SeamListener
      java.lang.NullPointerException
       at sun.beans.editors.BoolEditor.setAsText(BoolEditor.java:38)

      Could you help me? I guess I have a configuration or deployment descriptor somewhere, but I don't where to look for.
