Class StartupStatusDisplayFilter

java.lang.Object

edu.cornell.mannlib.vitro.webapp.filters.StartupStatusDisplayFilter

All Implemented Interfaces:

javax.servlet.Filter

public class StartupStatusDisplayFilter
extends Object
implements javax.servlet.Filter

No matter what URL is requested, check to see whether the StartupStatus contains errors or warnings. If it does, hijack the request to show the StartupStatus display page. If the status only contains warnings, this only happens once. Subsequent requests will display normally. However, if the status contains a fatal error, this filter will hijack every request, and will not let you proceed.
