Cell ID taglib ver. 1.2

    Custom JSP tags library for mobile developers. Lets you obtain geo coordinates for the given Cell ID. Cell ID is the unique number of a GSM cell for a given operator. Any phone is always connected to some cell, and by knowing this number, you know the Cell, and by knowing the position of the cell, you know where your phone is. There are some accuracy issues, as the cell can cover from several hundreds of meters to several kilometers, but this could be a very good starting point to locate the phone. Tag requests data from OpenCellID.
 

and you will get this:
 

Tag requests the database and creates 3 page scope variables (type is java.lang.String):
 
CellIDStatus - status of the request
CellIDLat - latitude
CellIDLng - longitude

Alternatively to mcc (mobile country code) and mnc (mobile network code) pair you can provide an attribute mccmnc (MCC/MNC tuple). In this case the first 3 digits will be used as mcc code and rest of the value as mnc.

You have to provide either mcc and mnc pair or MCC/MNC tuple.
