Hi,
I'd like to add that I am also experiencing this issue except with registering
custom property functions with Fuseki main server. The module is added to the
classpath when I start Fuseki Server, and I load the class in the global
assembler config.ttl file.
[] rdf:type fuseki:Server ;
ja:loadClass "com.example.jena.myFunc" ;
.
With my custom property function, Fuseki used to previously call the static
void init method on my class. But now, it no longer calls it and I can't
register the custom property function with my own IRI.
class getParts : PFuncSimpleAndList() {
companion object {
@JvmStatic
fun init() {
println("Initializing getParts property function")
// Register the property function with the IRI
PropertyFunctionRegistry.get().put(
"https://linked.data.gov.au/def/cn/func/getParts";,
GetPartsPropertyFunctionFactory(),
)
}
}
The above is in Kotlin, but hopefully you get the idea.
Note that I can still use the custom property function in my SPARQL queries if
I use the <java:...> syntax but I'd prefer it if I can continue to use the init
hook to register my function with an IRI.
Cheers,
Edmond
