Using an attribute set in a servlet as a bean in a JSP

Question

Say, I have saved an attribute in any scope in a servlet or its helper class using setAttribute("xyz", someObject).
* Would I be able to access this attribute in a subsequent JSP using <jsp:getProperty name="xyz" property"someProperty" /> *
The reverse works true ie. setting the attribute first as a bean in a jsp and den accessing it using getAttribut

Lakshminarayanan,
Actually, there are 2 ways to share data between WD components:
1. Context mapping
2. Combo of parameters to methods / parameters in events.
Say, you want to synchronize your 2 toolbars. You may declare some method(s) to alter state in "toolbar" component interface and some event(s) about state update. Now main component has to subscribe to this event from every component usage and invoke method in other component usage to synchronize state.
With context mapping you may achieve state synchronization automatically. Also method/event pair will look plain ugly if you have a lot of parameters or complex structures.
