A view could be anything. ZEST simply forwards the request to the given URI (by invoking javax.servlet.RequestDispatcher).

Since all implicit objects, except request[1], are stored as the request's attributes, they can be retrieved easily in the targeted view. For example, you could retrieve the action with an EL expression as follows, if the technology supports EL expressions, such as ZUML and JSP.

<p>${action.message}</p>

  1. The request is not stored since it is supported by almost all technologies. For example, in ZUML, you could use execution to retrieve it.
