Hi Christian, thanks a lot. Creating a .basexhome within the folder did the trick. After first (expected failed) start up, a .basex file was automatically created, which allowed the further configuration. I am using basexhttp - for that I had to add HTTPPORT = XYZ to the .basex file. Additionally I had to change the jetty Port in jetty.xml under /webapp/WEB-INF. Everything is working fine now! Thanks a lot! Best regards Alexander ________________________________ Von: Christian Grün <cg@basex.org> Gesendet: Montag, 18.

If you start BaseX from this directory, the global configuration settings will be ignored [1], and you can use completely different settings for custom instances of BaseX. Hope this helps, Christian [1] https://docs.basex.org/main/Configuration
