Neo4J Rest Data Graph - using SpringData - connection refused exception

Question

I have a project that use successfully a Neo4J embedded data graph, using SpringData. I'm trying now to change it to REST database, with no success.

I followed the (simple) instructions and it should have been really easy and straight forward, but I keep getting exceptions on server startup.

I set the server, as in the examples, to http://localhost:7474/db/data/ and I get 'connection refused' when starting the Tomcat. I would like to mention that currently I'm running this code on my local PC using Eclipse. Should I have done something else? install something? create some local libraries? -- because I didn't. I only installed 'Neo4J Community' which I used to view the embedded database.

This is the my application context:

This is the Exception I get when starting Tomcat:

And finally, I'm using:

• Maven
• Spring 3.2.4.RELEASE
• spring-data-neo4j-rest 2.3.1.RELEASE

Answer 1

Well, I guess this was a foolish question, because the one thing I didn't realize, is that unlike the embedded DB, I should manually start the Neo4 server from the Neo4J community. Everything else was fine...
