Custom flow with selection UI

Thank you for clarifying.

I have another question about the External authentication.
Currently, the servlet that handle the External authentication is in a jar
file inside the edit-webapp/WEB-INF/lib directory (copying the web.xml file
from the dist directory) and I use the sample code here:
complete the authentication.

The external path in the file is configured as follows:
idp.authn.External.externalAuthnPath = contextRelative:Authn/External

According to the documentation I can redirect the request to a specific URI
so I built a simple Java web application hosted on the same IDP machine
with a servlet to receive the requests.
This application only includes the shibboleth libraries to use the
ExternalAuthentication class and the web.xml has not been modified but I
get the
No FlowExecutor available in servlet context error.

Am I missing some configuration?

Thank you,
