Hi,
I'm completely new to Neo4j and got an issue while trying the getting started
guide.
Everytime I close the database (GraphDatabaseService.shutdown()) and open it
again later, all data is gone (or was never saved). I did exactly as described
in the guide, so maybe someone can point me in the right direction? Probably
just some stupid mistake by me. ;)
My tiny test case (Windows, Java 1.6):
Writing data:
GraphDatabaseService db = new EmbeddedGraphDatabase("/temp/neo4j/test1");
try {
org.neo4j.graphdb.Transaction tx = db.beginTx();
try {
Node rootNode = db.getReferenceNode();
Node firstNode = db.createNode();
rootNode.createRelationshipTo(firstNode,
IdabaRelTypes.ROOT_TYPES);
} finally {
tx.finish();
}
} finally {
db.shutdown();
}
Reading data:
GraphDatabaseService db = new EmbeddedGraphDatabase("/temp/neo4j/test1");
try {
org.neo4j.graphdb.Transaction tx = db.beginTx();
try {
Node rootNode = db.getReferenceNode();
for (Relationship rel : rootNode.getRelationships()) {
// output test data, but nothing in it
}
} finally {
tx.finish();
}
} finally {
db.shutdown();
}
Thanks in advance,
Roman
