java - get distance between two places -

-

i trying find distance between 2 places, new this. came know openstreetmap. not sure do.

i found traveling salesman application uses osm route. here question how osm between places .e.g. "http://www.openstreetmap.org/api/0.6/map?bbox=10,30,10,30" gives me map of box (10,30,10,30) .. if want map between leeds , sheffield should query.

or there other way find distance.(as student want open source way academic project..)

please suggest..

for calculating routing distance between 2 places can use 1 of various online or offline routers. there list of various information routing developers containing list of libraries , other information.

if have obtain location of specific address before doing actual routing can use nominatim.
