Java with Neo4j Error

[Zaina]

Hello,

I am new to neo4j and I get the following error with my first program in java with neo4j.

Exception in thread "main" org.neo4j.driver.v1.exceptions.ClientException: Authentication token must contain: 'scheme : basic' (ID:EED198F090FE487133CF552B3EECE6AE7E0E1F38FBB7E71323D46405404FF838)

 My code is as following:

package testone;

import org.neo4j.driver.v1.AuthTokens;

import org.neo4j.driver.v1.Config;

import org.neo4j.driver.v1.Driver;

import org.neo4j.driver.v1.GraphDatabase;

import org.neo4j.driver.v1.Record;

import org.neo4j.driver.v1.Session;

import org.neo4j.driver.v1.StatementResult;

public class testsub {

public static void main(String[] args) {

Driver driver = GraphDatabase.driver( "bolt://localhost",

Config.build().withEncryptionLevel( Config.EncryptionLevel.REQUIRED ).toConfig() );

System.out.println("Connection success");

Session session = driver.session();

session.run( "CREATE (a:Person {name:'Arthur', title:'King'})" );

StatementResult result = session.run( "MATCH (a:Person) WHERE a.name = 'Arthur' RETURN a.name AS name, a.title AS title" );

while ( result.hasNext() )

{

   Record record = result.next();

   System.out.println( record.get( "title" ).asString() + " " + record.get("name").asString() );

}

session.close();

driver.close();

}

}

I hope you can help me with this problem and if there is a video or tutorial that can help me to start working on neo4j with java.

Best regards,

You didn't provide auth information. I think the error message should be more informative. (Nigel)

You can find more information here in the docs:

http://neo4j.com/docs/developer-manual/current/drivers/#driver-driver

Driver driver = GraphDatabase.driver( "bolt://localhost", AuthTokens.basic("neo4j", "<pwd>"), ....

There are also other examples here:

https://neo4j.com/developer/java/#neo4j-java-driver

and an example application here: https://github.com/neo4j-examples/neo4j-movies-java-bolt
