The timeouts won't work if you use vaadin UI because a web application uses http session timeout. The [[https://vaadin.com/docs/-/part/framework/application/application-environment.html|vaadin documentation]] contains information about //Session Timeout After User Inactivity//. Our //WebApplicationSetup// implementation overrules the session timeout properties of config.xml by setting: <file java> launcher.setParameter("Application.connection.timeout", Boolean.FALSE.toString()); launcher.setParameter("Application.subconnection.timeout", Boolean.FALSE.toString()); </file> If set to false, the timeouts will be set to -1 (= infinitly). This is the default behavior with WebApplicationSetup but it's also possible to configure custom timeouts for master and sub session by adding the timeout constants: <file script> "Application.connection.timeout" "Application.subconnection.timeout" </file> as parameters to the deployment deskriptor (web.xml): <file xml> <init-param> <param-name>Application.connection.timeout</param-name> <!-- 30 minutes --> <param-value>30</param-value> </init-param> </file>
