There is another way to control the same thing. In /conf/catalina.properties you can use following property to stop scanning for TLDs: tomcat.util.scan.StandardJarScanFilter.jarsToSkip=*.jar But please remember, values of tomcat.util.scan.StandardJarScanFilter.jarsToScan property will override it. > If you know the Tomcat 9 equivalent, that would be really helpful. > > Thanks! > > Blake > > > On Wed, Apr 13, 2022 at 1:59 AM Thomas Hoffmann (Speed4Trade GmbH) > <thomas.hoffm...@speed4trade.com.invalid> wrote: > > > > -----Ursprüngliche Nachricht----- > > > Von: Blake McBride <blake1...@gmail.com> > > > Gesendet: Dienstag, 12.
