Help Needed - GPS to Oracle AS Wireless

Question

We have a client who is looking to implement a vehicle tracking solution inside a current application. This is a new concept to our development team and we require some assistance. I'm hoping that someone can provide me some answers to the following questions.
1. How does a GPS device communicate with Oracle AS wireless.
2. Do the GPS coordinates require a specific format.
We have absolutely no knowledge in this area. Any information regarding what GPS devices are best suited or past experiences that could be useful would be much appreciated.
Thank you

Hi,
there two ways, to update the AS Wireless's location cache, with a mobile clients GPS position:
1) You can write an application for the mobile device, that reads the GPS coordinates and sends them to a service (for example a jsp-appl) on the server.
The jsp-appl then calls the AS Wireless LBS-API, that updates the location cache.
(I have copied a code example at the end, that does this)
2) You can write an application for the mobile device, that reads the GPS coordinates and calls the MP Web Service at Wireless server.
You can find more info about AS Wireless LBS

There is also a chapter in the
Oracle® Application Server Wireless Developer’s Guide
describing this, please see:
15.3.2.1 Providing Location Using a GPS Device
A mobile device can send its current location, usually provided through a global
positioning system (GPS), to the OracleAS Wireless server. The current location can then be queried using the mobile positioning and privacy APIs.
You must create a client application program that runs on the mobile device and posts the device's current location to the OracleAS Wireless server. The data can be posted either to a JSP running on the OracleAS Wireless server or through a Web service.
Sample from my J2EE-application(ex. set_position.jsp), at Wireless Server, that saves GPS coordinates in Wireless's Location cache:
// URL to the MP Web Service at Wireless server
final String theSOAPurl = "http://[Your_AS_Wireless_Server]/location/webservices";
try {
MPSoapClient mpsc = new MPSoapClient(theSOAPurl, "urn:MobilePositionServer");
System.out.print("Setting the location of a mobile user ... ");
String xmlReq = "<?xml version= '1.0' encoding='ISO-8859-1' standalone='yes'?>\n" +
"<MP_GPS>\n" +
"<USERNAME>" + theUserName + "</USERNAME>\n" +
"<PASSWORD>" + thePwd + "</PASSWORD>\n" +
"<MSID>" + theMSISDN + "</MSID>\n" +
"<POS>\n" +
"<LAT>" + theLat + "</LAT>\n" +
"<LONG>" + theLon + "</LONG>\n" +
"</POS>\n"+
"</MP_GPS>";
System.out.println(xmlReq);
String theResult = mpsc.setPosition(xmlReq);
System.out.println(theResult);
catch (Exception e)
e.printStackTrace();
