Hi Christian,

I was using BaseX 9.5 on Tomcat 8.5 and it was fine.

On Tomcat 10.0.2 I couldn't get either BaseX 9.5 or 9.7 to work (same issue).

I now have Tomcat 9.0.62 running and I've successfully run both BaseX 9.5 and 9.7.
 
Regards
Marc

Hi Marc,

I remember there were problem with a past release of BaseX and Tomcat.
Which version of BaseX are you using?

Best,
Christian
