Hi,

I am using a BB Curve 8700(trackwheel) device.I have been developing applications for blackberry and am new to this. I have developed an application which connects to the server on internet and gets some response.

Some Facts :
1. I have a Vodafone connection(India) and all services are activated.
2. I am able to browse the internet from the device browser.
3. The application is signed.
4. The Http is handled in a seperate thread.
5. Device OS version is 4.2.1.114


Here is the code...

public void run() {
HttpConnection cnx;
InputStream is;
try
{
System.out.println(mainURL); //This is getting printed
cnx = ( HttpConnection )Connector.open( mainURL ); //Exception here

//This sysout is not reached at all
System.out.println("cnx="+cnx+ " " +cnx.getResponseCode());

if(cnx.getResponseCode()==HttpConnection.HTTP_OK)
{
//Do some processing here
}
cnx.close();

} //end of Try

catch(Exception e)
{
returnResp=false;
System.out.println("Exception = "+e); //Displays java.lang.NPE
}

The Connector.Open() is throwing an exception and a Null Pointer Exception is caught.Verified that 'mainURL' is not NULL. Dont know why NPE is thrown !!!

This same piece of code works perfectly fine on my other BlackBerry Bold device(9000) with the same SIM card. All basic settings are similar in both the devices.

Please suggest me a solution to make this work.Thanks in advance.

Have you looked at the stack trace? You have this "do some processing here" which could be anything - this is likely where your NPE is getting thrown.

Get all of this code out of the try/catch - it shouldn't be there.
