Hi Gabriel,

This seems to be an exception raised by Charles Foster's XQJ driver.
What happens if you run the same query with BaseX on command-line or
in the GUI? Which output on stdout/stderr do you get by activating the
BaseX debug mode?...

  XQConnection xqc = ...;
  XQExpression xqe = xqc.createExpression();
  xqe.executeCommand("set debug true");

Best,
Christian
