Hi,
I am new to Neo4j Spatial and trying to play with it. I have built neo4j
spatial by cloning the git repo and running 'mvn clean install'. In my Java
project I am pointing to this built jar and I am trying to import
Washington DC's OSM file using the code below:
OSMImporter importer = new OSMImporter ("WashingtonDC");
Map<String, String> config = new HashMap<String, String>();
config.put("neostore.nodestore.db.mapped_memory", "256M" );
config.put("dump_configuration", "true");
config.put("use_memory_mapped_buffers", "true");
String dir = "/dev/neo4j-spatial/db";
BatchInserter batchInserter = BatchInserters.inserter(dir,config);
importer.importFile(batchInserter, "/downloads/dc-baltimore.osm",false);
batchInserter.shutdown();
GraphDatabaseService db = new
GraphDatabaseFactory().newEmbeddedDatabase(dir);
importer.reIndex(db,10000);
db.shutdown();
However, upon running this example I get the following error:
Exception in thread "main" java.lang.NoClassDefFoundError:

... 7 more
I am guessing a dependency issue. I would appreciate any help.
Thanks
Sumit
