+    The framework uses a standard naming context to evaluate OGNL expressions. 
+    The top level object dealing with OGNL is a Map (usually referred as a context map or
context).
+    OGNL has a notion of there being a root (or default) object within the context. 
+    In OGNL expressions, the properties of the root object can be referenced without any
special "marker" notion.
+    References to other objects are marked with a pound sign (#).
+    
+    In this example (and in your JSP pages) the last action executed will be on the top of
the stack.
