I am using keycloak-saml-servlet-filter-adapter.

I would like to run the module with Tomcat 10, that uses Servlet 5.0 and Jakarta EE 9.

Java 17 will drop support for older javax.\* namespaced libraries from Jakarta EE 8 and earlier.

The source code of keycloak dependes on  
jboss-servlet-api\_3.0\_spec or jboss-servlet-api\_4.0\_spec which is incompatible with Tomcat.
