Can you explain what you mean with "where "graph" is a graph name in your yaml file." in more detail? Thank you for your patience

Maybe I am missing an import in the gremlin-server.groovy or a processor or serializer in the gremlin-server.yaml?

Just using the plugin jars I got a step further. Cool!

Setup and Configuration of SPARQL-Gremlin plugin (with ArcadeDB)
I had the same feeling, given the error java.lang.ClassNotFoundException: org.apache.tinkerpop.gremlin.sparql.jsr223.SparqlGremlinPlugin. The line to add to the gremlin-server.yaml being org.apache.tinkerpop.gremlin.sparql.jsr223.SparqlGremlinPlugin: {} is correct, right?

Setup and Configuration of SPARQL-Gremlin plugin (with ArcadeDB)
Hi, I have two follow up questions: 1. Which subfolder jars of ext/sparql-gremlin do I need to copy: lib or plugin? I copied both but there seem to be duplicates. 2. I get now the log output with the above suggested config in the gremlin-server.yaml:

Thank you nonetheless, this is a good foundation to start experimenting more. I will come back with further questions if necessary.

This could be the case. The logs just state: GremlinServer plugin started

Running g = traversal(SparqlTraversalSource) results in the error: No such property: SparqlTraversalSource for class: Script8. About the init script, I can't say either.

Setup and Configuration of SPARQL-Gremlin plugin (with ArcadeDB)
Hi @spmallette , Thank you for your reply. I performed the two steps you suggested (I manually copied all the jars below ext/sparql-gremlin to the folder holding ArcadeDB's jars), but I get, when using g.sparql("""SELECT * WHERE { ?x ?y ?z . }"""), the error No signature of method: org.apache.tinkerpop.gremlin.process.traversal.dsl.graph.GraphTraversalSource.sparql(). Also when running graph = TinkerFactory.createModern() I get the error No such property: TinkerFactory for class: Script5.
