I'm trying to export Neo4j graph (with 4318 nodes & 8145 Relationships) for testing using gremlin-groovy-2.3.0 using:

  g = new Neo4jGraph('/tmp/mygraph');
  g.saveGraphML('mygraph.xml');

but getting list of errors when typing the 1st command in console (gremlin-groovy-2.3.0/bin/gremlin.bat), Last line of error:

Error:   Component: 'org.neo4j.kernel.StoreLockerLifecycleAdapter@5e1a7112 was successfully initialized, but failed to start

I have copied the Neo4j database (\data\graph.db) to Gremli (gremlin-groovy-2.3.0/bin/tmp/mygraph).

Sometimes it runs without error but then shows below error: gremlin graphdb to graphml

how to export ?

  • i don't see an error in your screenshot. also...if you've copied the database files of neo4j to `gremlin-groovy-2.3.0/bin/tmp/mygraph` then your path to the database is bad (pointed at the root of the file system) and you should do something like `new Neo4jGraph('bin/tmp/mygraph')` – stephen mallette Jul 09 '13 at 13:26
  • still it is giving Null ? – user2216267 Jul 09 '13 at 15:24

    `null` does not necessarily imply an error. That is expected output as there is no return value of `saveGraphML`. Indeed, a successful call to that method will show null to the REPL (check the location for where you wrote the file to and you should see `mygraph.xml` present. I would expect an "error" to produce some stack trace to the REPL. – stephen mallette Jul 09 '13 at 15:54
  • i have copied the folder (\neo4j-community-1.9\data\graph.db) to (gremlin-groovy-2.3.0\bin\tmp\mygraph) ....is this what i need to do ? – user2216267 Jul 09 '13 at 16:31

    not sure that you need to copy it at all. why not just point `Neo4jGraph` at the neo4j directory (assuming that you don't have the graph running in some other process)? I assume that the `graph.db` directory has all the files that `Neo4jGraph` needs (but i'm not familiar with how Neo4j runs natively outside of Blueprints). – stephen mallette Jul 09 '13 at 17:11
  • sir, how to "point Neo4jGraph at the neo4j directory" ? – user2216267 Jul 09 '13 at 17:14

    i just mean that if your neo4j data is here: `\neo4j-community-1.9\data\graph.db` then make sure that neo4j is not running in some other process and open the graph from the gremlin prompt `g = new Neo4jGraph('\neo4j-community-1.9\data\graph.db')` – stephen mallette Jul 09 '13 at 18:07
