Xwiki install with fedors-server

Good evening,
I have the following problem with the Fedora (rpm) based xwiki embed under Wildfly. both applications are up to date.

Wildfly always gives an error that xwiki does not have a valid mysql/mariadb schema.

who has experience setting up and configuring Fedor’s Wildfly and xwiki.

the adjustments the https://www.xwiki.org/xwiki/bin/view/Documentation/AdminGuide/Installation/InstallationWAR/InstallationJBoss/
have not solved my concern.
