scala - Preparing to use neo4j bolt with Play Framework -


i want access neo4j db play framework application in addition mysql db. mysql access working properly. in preparation code accessing neo4j via bolt, have:

added reference driver in project build.sbt:

librarydependencies ++= seq(   jdbc,   cache,   ws,   specs2 % test,   "org.mindrot" % "jbcrypt" % "0.3m",   "mysql" % "mysql-connector-java" % "5.1.38",   "org.neo4j" % "neo4j-bolt" % "3.0.1" )

and restarted activator , watched apparently resolve/retrieve dependency can find in ~/.ivy2/...

i have placed reference database in application.conf seen in snippet:

db.default = {   driver: com.mysql.jdbc.driver   url: "jdbc:mysql://127.0.0.1/borg"   username: "borg"   password: "xxxxx" }  # bolt port # defaults 7687 hope db.neo4j = {   driver: org.neo4j.jdbc.driver   url: "jdbc:neo4j:bolt://neo.myco.com"   username: "neo4j"   password: "xx" }

i have not yet written scala code attempt accessing db. adding specification application.conf causes application fail when retrieved site messages seen in following stacktrace. note message "driver not found [org.neo4j.jdbc.driver}]", curiously has right brace in peculiar location. wonder if red herring. insights or experience out there?
