[ https://issues.jboss.org/browse/WFLY-3584?page=com.atlassian.jira.plugin.... ] Farah Juma commented on WFLY-3584: ---------------------------------- As mentioned in WFLY-2691, the error page doesn't get displayed because of the way Undertow's development mode works (for more details, see the explanation [here|https://issues.jboss.org/browse/WFLY-2691?focusedCommentId=12942763&...]). To allow your error page to be displayed, set the 'stack-trace-on-error' attribute in the <servlet-container> element in the Undertow subsystem to 'none' as follows: {code} <servlet-container name="default" stack-trace-on-error="none"> <jsp-config/> </servlet-container> {code} Also, the location of the error page needs a leading forward slash, e.g., {code} <error-page> <location>/default.xhtml</location> </error-page> {code} With these two changes, the configured error page should be displayed when the session times out. -- This message was sent by Atlassian JIRA (v6.2.6#6264)
