Greetings I just downloaded BaseX 8.3.1 .war and installed it on Tomcat 7 (jre1.8.0_66) running Windows 7. enterprise (SP1). Did nothing (just loaded a single XML file) throught the web based admin interface and tried this XQuery import module namespace geo = "http://expath.org/ns/geo"; declare namespace gml='http://www.opengis.net/gml'; let $point := <gml:Point><gml:coordinates>1,2</gml:coordinates></gml:Point> return geo:geometry-type($point) (it's from Geo Module documentation at http://docs.basex.org/wiki/Geo_Module#geo:geometry-type) all I get is *[XPST0017] Unknown function 'geo:geometry-type'.* in the logs, I have [POST] http://localhost:8080/BaseX831/dba/eval-query?name=&resource=&sort=&loglist=; Stopped at C:/Program Files/Apache Software Foundation/Tomcat 7.0/webapps/BaseX831/dba/modules/util.xqm, 94/17: [XPST0017] Unknown function 'geo:geometry-type'. The java Geo.class are present (webapps\BaseX831\WEB-INF\classes\org\expath\ns) Other trivial XQuery do work Any idea what's wrong ? Thanks and Happy New Year
