Answer 1

Enumeration<String> attributes = request.getSession().getAttributeNames();
while (attributes.hasMoreElements()) {
    String attribute = (String) attributes.nextElement();
    System.out.println(attribute+" : "+request.getSession().getAttribute(attribute));
}

Answer 2

        Enumeration e = (Enumeration) (session.getAttributeNames());

        while ( e.hasMoreElements())
        {
            Object tring;
            if((tring = e.nextElement())!=null)
            {
                out.println(session.getValue((String) tring));
                out.println("<br/>");
            }

        }

this code is also working perfectly thanks for the spark reply @karim mohsen
