How do i track mobiles using GPS, J2ME
Dear All,
I want to develop a mobile tracking system, which should tbe able to track all kinds of mobile phones. The mobile tracking system fucntionality should include-  tracking the Global positions of the mobiles phones and sending their coordinates on the network (using GSM/3G). The received coordinates should in turn be send to a server over 3G network and the server should be able to display the coordinates.  

Thank you.

Dear MicheleMarcon,
i have developed a GPRTRacking system, there are three part in this project, The database, the Website and the Phone.My 2 parts website and database are working well (in Visual Studio).but in my third part -Phone, i have a problem.
The part Phone- it gets the gps location based on an interval in seconds. for instance,
    -the location is gotten once a minute, sent to the website to be stored in
    -the DB (and then viewed on Google map) and used to retrieve a map tile (image)
    -to be diplayed on the phone
The problem is that when i am running it (the third part-Phone),(using NetBeans), the map is not being displayed from the website. i am getting a message-
NetWorker.getUrl: java.lang.IllegalArgumentException:
Map could not be downloaded.

I have been reading the source code for Phone(written in java), and i dont know where the fault is?.
Please help me.
thanks.

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
