Exception that I injected was null. But I could get that exception as Exception excp= (Exception)Contexts.getConversationContext().get("org.jboss.seam.handledException"); if (excp != null && excp instanceof Exception) { System.out.println("error" + excp.getClass().getName()); excp.printStackTrace(); but printStacjTrace doesnt print anything now. But esxception class name is proper. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4126046#...
