What do you mean here with "after"? Batch geocoding *is* converting the addresses into latitudes and longitutdes, no point in doing the same thing twice. but i wanted to know if we can convert the given addresses into > latitudes and longitudes on the fly using JAVA? so that when i get the > 20 addresses i will convert them and then send the values to google > maps...wat say? > Not sure what you mean here. The Geocoding API is an HTTP interface, so you can sent requests from any runtime environment you need (Java, Python, PHP, etc.) However, if you are thinking about throwing out 20 geocoding requests each time a user visualizes 20 markers, that's prone to give you even more trouble that doing it on JavaScript. The correct approach would be to run all addresses through a batch-geocoding process what would update your database adding the LatLng position for each row. Later on, when each user visualizes 20 (or 200) of those on a map, not a single geocoding request would be needed, because coordinate are already in the data base.
