Hi,
I use twitter4j with neo4j, i try to insert index but it doesn't work, i
have this error :
at
org.neo4j.kernel.impl.transaction.AbstractTransactionManager.assertInTransaction(AbstractTransactionManager.java:84)
at
org.neo4j.kernel.impl.coreapi.IndexManagerImpl.assertInTransaction(IndexManagerImpl.java:466)
at
org.neo4j.kernel.impl.coreapi.IndexManagerImpl.forNodes(IndexManagerImpl.java:301)
at
org.neo4j.kernel.impl.coreapi.IndexManagerImpl.forNodes(IndexManagerImpl.java:294)
this is my code:
private void createDB()
{
_graphDB = new GraphDatabaseFactory().newEmbeddedDatabase(DB_PATH);
System.out.println("bd acces"+_graphDB);
_entitiesIndex= _graphDB.index().forNodes( "twitterEntities" );
System.out.println("index entite ajoutée : \n"+_graphDB);
_UserIndex= _graphDB.index().forNodes( "User" );
_TwittIndex= _graphDB.index().forNodes( "Twitt" );
_URLIndex = _graphDB.index().forNodes( "URL" );
_HashtagIndex= _graphDB.index().forNodes( "Hashtag" );
_MediaIndex= _graphDB.index().forNodes( "Media" );
_relMENTION = _graphDB.index().forRelationships("Mention");
_relTWITT = _graphDB.index().forRelationships("Twitt");
_relHASHTAG = _graphDB.index().forRelationships("Hashtag");
_relURL = _graphDB.index().forRelationships("URL");
_relMEDIA = _graphDB.index().forRelationships("Media");
_relRT = _graphDB.index().forRelationships("RT");
WrappingNeoServerBootstrapper srv;
srv = new WrappingNeoServerBootstrapper((GraphDatabaseAPI) _graphDB );
srv.start();
