I'm trying to develop a simple REST WS that connects to an embedded Neo4J DB that runs locally on my machine. First I got a simple GET operation just returning a simple String when the Service was called and that works normally. Now I'm trying to get this to really do something so I've searched a couple of tutorials on how to integrate Spring with Neo4J. The truth is I've found this to be much more tricky than what I was expecting, mainly because there's a lot of tutorials and they all look different, so there's like 100 different ways to do it and I'm trying to adapt to my solution. I'm not sure on my Annotations and also on my XML configuration files. Any help is apreciatted. May the Force be with me. :)
UPDATE_1: this is myStore servlet now

And now the error related to the Autowired object.

The error continues on and on, but I think this the important part. If u need to see anything else of the log error let me know.
Thank in advance
