What about something like this:
Enumeration names = session.getValueNames();
while (names.hasMoreElements()) {
String name = (String) names.nextElement();
Object bean = session.getValue(name);
System.out.println("Session bean '" + name + "' has value '" +
bean.toString());
}
(In a 2.2 servlet container, you would replace getValueNames() by
getAttributeNames() and getValue() by getAttribute() -- these names were changed
for consistency with the other scopes.)
Obviously, you can do anything else with all of the values that you need. The same
concept applies to request attributes and servlet context attributes -- in each
case, you can get an enumeration of the names, and therefore have access to all the
values.
