http connection throws java.io.IOException: Status=-20

[adiwin]

Hi all,

I got a problem when i tried to open Input stream after opening http connection on my Actual 7650 device. The system throws java.io.IOException: Status-20 , Anyone knows workaround to solve this problem ? or Anyone successfully make http connection and open Input stream in the actual device ?

I have tried to put the connection part into a thread and configure my wap gateway to (0.0.0.0). I am suspecting this might be http header problem.

regards

i also had a similar problem, on first attempt to get a page from internet via GPRS, my app throws IOException : Status -2 and on the next attempt it throws IOException: Status -20019. It does works fine on the emulator, but on the real 7650 devices, what does the status code means?
i had a deadline to meet in these few days and the app has finished and stuck in these http connection on the real devices.
I really hope one of the technical support at Nokia can comment on this, or post a solution.

// the code to get a webpage
try{
String url = "http://www.myserver.com/getString.asp?id=1";
String ret = getViaHttpConnection(url);
}catch(IOException e){e.printStackTrace();}

here is the code to get a page from java.sun.com (javatips)
-----------------------------------------------------------
public static String getViaHttpConnection(String url)
throws IOException
{
HttpConnection c = null;
InputStream is = null;
StringBuffer strBuffer = null;
c = (HttpConnection)Connector.open(url);
// Getting the InputStream will open the connection
// and read the HTTP headers. They are stored until
// requested.
is = c.openInputStream();
// Get the ContentType
String type = c.getType();
// Get the length and process the data
long length = c.getLength();
if (length > 0)
strBuffer = new StringBuffer((int)length);
else
strBuffer = new StringBuffer(); // default length
int ch;
while ((ch = is.read()) != -1)
{
strBuffer.append((char)ch);
}
if (is != null) is.close();
if (c != null) c.close();
String returnStr = "";
returnStr = strBuffer.toString();
return returnStr;
}

best regards,
