Cell ID taglib ver. 1.1


    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.
 


<%@ taglib uri="taglib.tld" prefix="c" %>

<c:CellID mcc="250" mnc="99" lac="0" cellid="29513" />

<p>CellIDStatus=<%=pageContext.getAttribute("CellIDStatus")%>
<br>CellIDLat=<%=pageContext.getAttribute("CellIDLat")%>
<br>CellIDLng=<%=pageContext.getAttribute("CellIDLng")%>

and you will get this:
 


CellIDStatus=ok
CellIDLat=54.4910893937777
CellIDLng=27.9390742994699

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