I am developing an application using J2ME to send the GPS coordinates received to the server and i am new to developing client server application.
Everything works fine with the use of Nokia N97mini or E71. But when i tried it on HTC HD2, i get the exception from the server. I am using Netbeans 6.5.1 GlassFish V2 as Server. I have no idea why this error occurs only on the HTC HD2. Any help will be greatly appreciated. Thanks...
Below is the error message:

Below is the code that i wrote to connect to the server:
private void connectFindHospServlet()
{
String url = "http://172.22.190.13:8080/UpdateServlet/FindHospitalServlet";
StringBuffer sb = new StringBuffer();
String info = lat+"!"+lng+"!";
try
{
HttpConnection c = (HttpConnection) Connector.open(url);
c.setRequestProperty("User-Agent","Profile/MIDP-2.0, Configuration/CLDC-1.0");
c.setRequestProperty("Content-Language","en-US");
c.setRequestMethod(HttpConnection.POST);
DataOutputStream os = (DataOutputStream)c.openDataOutputStream();
os.writeUTF(info);
os.flush();
os.close();
// Get the response from the servlet page.
DataInputStream is =(DataInputStream)c.openDataInputStream();
int ch;
sb = new StringBuffer();
while ((ch = is.read()) != -1)
sb.append((char)ch);
is.close();
c.close();
if(sb.toString().charAt(0) == 'n')
{
formDisplayResultFindHosp();
display.setCurrent(formDisplayResultFindHosp);
}
else
{
PlannerMain pm = new PlannerMain();
hospInfo = pm.getFindHospInfo(sb.toString().substring(0, sb.length()-2));
formDisplayResultFindHosp(hospInfo);
display.setCurrent(formDisplayResultFindHosp);
}
}
catch (Exception e)
{
System.out.println("Error recieve find user");
}
}
Any information needed to better help in understanding the problem, do let me know. I will try to provide as much as possible.
