Hi,
I followed the docs and examples on calling Java functions from XQuery, but when I try and add a package to the repository that calls one of my own functions BaseX complains that it can't find the function. I am running BaseX locally and the class I want to call is in my project's classpath. Any ideas as to what I'm doing wrong?
Cheers Gary
Hi Gary,
we are frequently using and embedding Java code in our projects. Do you have a quick example?

Sure, here's the module I'm trying to load:
module namespace ts="www.tspotter.net"; declare namespace xqc="net.tspotter.sdk.plugin.model.XQueryCalculator";
declare function ts:getEntryFromPrimaryKey( $primaryKey as xs:string ) { let $expression := xqc:getEntryXPath( $primaryKey ) return xquery:eval( $expression ) };
And then in my java class I have:
public class XQueryCalculator { public static String getEntryXPath( String id ) { // do some stuff return ret; } . . . }
Is there anything else you need to see?
Cheers Gary

Does your code work if you remove the "static" flag from the getEntryXPath function? ___________________________

I tried adding a member function to see if that worked, but it didn't. I've now recoded my Java function in XQuery, but I would still like to get to the bottom of why it's not working as I'm sure I'm going to want to use this feature again soon.
Cheers Gary

I've tried your little example. It works fine on my system, so feel free to send me an sscce, which allows us to reproduce the issue locally.

I have a suspicion that it's an issue with how the basex jar file is being loaded - in my project it's being loaded as part of an eclipse plugin and therefore my class won't be on it's classpath.
