Hi Arthur,
The error message could indicate that you are using an outdated version of XQJ. Are you working with the XQJ libraries that are contained in the lib directory of BaseX?
Hi! I’ve downloaded BaseX 9.2 (Windows distro).
As the latest official release is 9.1.1… Is it the snapshot that you have downloaded?
java.lang.NoClassDefFoundError: org/basex/core/Proc
Could you please pass us on your Java code?
Best, Christian
