Hi, I'm new to basex and I'm trying to build an external java library which will return a list of documents for me to then query, but I'm running into a problem where it can't seem to find the class. This is the script I'm running: declare namespace t = "java:com.inkling.modules.Test"; let $loader := t:new("local") return ( t:fileNames($loader) ) In my root project directory I have a subdirectory for my java files so I start up the baseX gui using java -cp "BaseX76.jar:xmldblib/src/" org.basex.BaseXGUI and my java file (in xmldblib/src/com/inkling/modules/Test.java looks like: public class Test { String env; public Test(String environment) { env = environment; } public List<String> fileNames() { ...... } } When I try and run the xquery script, it just says Unknown Constructor Test.new(xs:string) Does anybody have an idea what I'm doing wrong? Any help is appreciated. Thanks, Joe
