public abstract class GeneralDispatchAction

extends org.apache.struts.actions.DispatchAction

An abstract Action which combines the functionality of the Struts DispatchAction and LookupDispatchAction classes.

• if the inverse lookup fails, the execute method of DispatchAction is called.
• if the request and server session ids do not match, indicating a session timeout, control is forwarded to the resource specified in the timeoutPage context init parameter
