I am trying to create a user defined function in Neo4j. I did it exactly as they did it in their examples: https://github.com/neo4j-examples/neo4j-procedure-template. After deploying and creating the JAR I copied the JAR into the plugins folder at
neo4j-community-3.4.9/plugins/ and also in
neo4j-community-3.4.9/data/databases/graph.db/plugins/. But the functions are not displayed when typing
CALL dmbs.functions(). When trying to use it like
return example.join(['a','b']) it just says following:
Neo.ClientError.Statement.SyntaxError: Unknown function 'example.join' (line 1, column 16 (offset: 15)) "return example.join(['a','b'])"
