How to call ld_dir, rdf_loader_run, checkpoint procedures using JDBC driver

Hello support

How to call
ld_dir,
rdf_loader_run,
checkpoint
procedures using JDBC driver?

I would like to automate the load of ttl files but using java. I do not see the proper method in the list of available methods. See image below.

Thanks!

Those Virtuoso specific procedures/functions are not methods in the Java specification obviously, but when you connect to Virtuoso via its SQL interface (ie with isql, ODBC, JDBC, ADO.Net etc) you can call these as procedures in the database as you would with the Virtuoso “isql” command line tool for the Virtuoso RDF Bulk Loader .
