Ich habe die notwendigen Gläser in/Plugin-Verzeichnis setzen. Im Folgenden sind die JAR-Dateien:
graphaware-reco-3.1.4.49.11.jar graphaware-server-community-all-3.1.4.49.jar my-reco.jar
Ich habe auch die notwendigen Konfigurationen in neo4j.conf wie in der Dokumentation erwähnt. Ich schaute in den Code von graphaware.
Eine "Could not start GraphAware Runtime because the database..." Nachricht erscheint, wenn falsche Ausgabe gibt (in meinem Fall sofort), die mich zu der Schlussfolgerung führen, dass meine Datenbank heruntergefahren wird. Ich sah die Baumstämme, um das genaue Ding zu bekommen.
Hier sind die Protokolle:

Kann mir jemand helfen mit diesem?
