Hello, Multi-tenant in a graph can be easy: simply use a different sub-graph for each tenant and let your application code bind to you a specific subgraph. If you want to go to the next step and have physically separate databases, that's harder. Are there reasons for wanting to do this, such

Re: [Neo4j] [neo4j] Exposing Webadmin

Hey Jake, [with my RESTafarian hat on] Will make the server move management stuff to that URI, and webadmin will follow suit. So for your case, you should be able to do: org.neo4j.server.webadmin.data.uri=/neo4jdb/db/data/ org.neo4j.server.webadmin.management.uri=/neo4jdb/db/manage/ I

Re: [Neo4j] Cannot launch neo4j on Mac OS 10.6.7

Hi Kevin, The install location shouldn't make any difference. Can I ask when you downloaded the package? We had a snaffu with our packaging mechanism just after we released. That was picked up and fixed, but there's a chance you might have a copy of the dodgy package. Jim
