HttpConnection getResponseCode() Error on 3650 and 7650 "Http-version mismatch"

[mkroll]

Hello Nokia Support,

### This issue is very important for me, since the project I'm working on is part of my Ph.D. thesis. So please answer ###

I have already posted some messages accodind to this issue but it seems that I can provide much more information in order to understand my problem.

After I have successfully trasmitted data using the HttpConnection's POST method, I just want to read the response code in order to see if the request was successful or not.

Whenever I call HttpConnection.getResponseCode() or HttpConnection.getResponseMessage() my phones throw an IOException. The Error Message is "Http-version mismatch". This error occurs on both phones:

Nokia 3650 firmware version 3.12
Nokia 7650 firmware version 4.46

I have tested the connection with gprs and normal data connection. Both resulting in the error message mentioned above.

On the Emulator the code works fine.

Thanks for help and a quick reply,

Best regards, Michael Kroll.

....I forgot to mention that the server is a Tomcat v 4.1.24 HTTP1.1. Perhaps there is a bug in the HTTP1.1 communication?

Thanks.

Hello,

What's your default language of the phone? In some old firmware S60 phones, if you are not using English (for example Finnish), "HTTP 1.1" is converted to "HTTP 1,1" when the header is send.

Kui

The default languange of my phones is German.
But I tried it with english as well, without luck.

BTW, the firmware on both phones isn't old, but the latest available.

Hi, I have the same error:

"java.io.IOException: HTTP-Version Mismatch"

I am using Nokia N97
The phone was bought in Italy, but I set the language to English, is there a difference between set language and default language of OS ?

I run my app. in emulator of N97 and it works ok.

My Code is (I took an example from nokia website and bit simplified it)
String getDataFromServer(){
String serverUrl = new String("http://www.google.com");
HttpConnection httpConn = null;
InputStream is = null;
String dataRead = "";
try{
httpConn = (HttpConnection)Connector.open(serverUrl);

// if((httpConn.getResponseCode() == HttpConnection.HTTP_OK)){
form.append(String.valueOf(HttpConnection.HTTP_VERSION));
int length = (int)httpConn.getLength();
is = httpConn.openInputStream();
int chunkSize = 1500;

} catch(Exception e){
System.out.println("Exception occurred during GET "+e.toString());
form.deleteAll();
form.append("\nNetwork failure in retrieving data from " +
"server. Try Again!\n");
form.append(e.toString());
form.append(e.getMessage());
Display display = getDisplay();
display.setCurrent(form);
}

return dataRead;
}

Output on display:
Network failure..... Again!
java.io.IOException: HTTP-Version Mismatch
HTTP-Version Mismatch

Thx, for quick reply
All the best

So I've got this problem solved, I brought it to "Nokia Care Point" and for a just "formal fee" of 30 EUR, I got the firmware reinstalled. Now I have firmware for UK and it works perfectly. Before I had Italian.

Hi Guys

I am also facing the same issue with my old Nokia E61 device.

Has anybody solved the issue without updating the software or changing the server side code.

What i mean is -- Is it possible to solve this issue programmatically ?

Thanks
Early reply appreciated !

Well that an interesting thing to know...
Would like to know that where exactly are you trying to get the response code and message in the code?

I will appreciate if you could put the Code?
