Neo4j Cross-Store - SQL DB empty, no error

**wer1** · Oct 24th, 2012, 01:37 AM

Hi at all,

I use Neo4j and the Neo4JTemplate to persist my Data.
I have a class named File. I would like to store the bytes field in an extra SQLite database (or all fields). Bellow you can see my configuration and classes.
If I save my File I get no errors but the database is still empty.
Maybe I forgot one statement or something. I hope you can help me.

Thanks,

Christina
