What kind of an offline map and how to use it in my javafx application ?

[ylen...@gmail.com]

Hi, i'm using javafx (fxml) to build an application, which i load data from "csv" files to neo4j database. Then i query it and display the results in tableview.Now some of the data are location  data. So i need a way  to display a full featured -with the zoom and search option- map  offline and use it for my location data. I have been looking for more then 15 days but no progress and to be honest and i don't even know what kind of a map  i should look for (i.e the file extension) because i have downloaded some files  from Openstreetmap with different  extensions  like  ".mbtiles", ".osm.pbf" and ".shp.zip".So if  anybody can help  ? Thanks in advance.
