Programmatically Jetty configuration

roi2 · February 4, 2019, 3:59pm

we’re trying to configure your simplest flow application (https://vaadin.com/start/latest/project-base) to work with programmatically jetty configuration (without maven)
following this https://vaadin.com/docs/v12/flow/production/tutorial-jetty.html
but we cant get this to work…

what are the imports for the ManualJetty class you have in your instructions?
should there be any difference between the vaadin 8 Programmatically-Jetty-configuration?
our flow app is getting up but we can’t see anything in the url and our mainView class is not even been initialized.
