Strange HTTP Issues

[stefanogalizia]

Hi to all for serveral days i'm trying to solve this problem without success. The problem occurs only on SERIE60_FP2. When i call the method

---->int rc=c.getResponseCode();

the device, also the emulator, hangs.




if i delete the code above the device,also the emulator, hangs on

---->is = c.openInputStream();


so every read call hangs-up.


The same code in other devices and emulators rather than SERIE60_FP2 (I.E. NokiaN70) works great. I've tested on the following real devices:

1. NokiaN70 OK
2. Nokia6630 KO V.5.03.08


and on a lot of emulator (excluding the SERIE60_FP2 emulator all the others works great)

Here is my source code:


byte[] GetHttpData(String url) throws IOException{
ByteArrayOutputStream byteStream = new ByteArrayOutputStream();
InputStream is = null;
HttpConnection c = null;
byte strData[]=null;
long len = 0 ;
int ch = 0;
try {
c = (HttpConnection)Connector.open(url);
c.setRequestMethod("GET");
int rc=c.getResponseCode();
is = c.openInputStream();
len =c.getLength();
if (lunghezzaTotale==-1) {lunghezzaTotale=len;}
if( len != -1) {
// Read exactly Content-Length bytes
for(int i =0 ; i < len ; i++ )
if((ch = is.read()) != -1) {
byteStream.write(ch);
}
} else {

//Read until the connection is closed.
while ((ch = is.read()) != -1) {
len = is.available() ;
byteStream.write(ch);
}
}
strData=byteStream.toByteArray();
}catch (IOException ioex){
mc.messaggio(ioex.toString(),this.mm,0);
} finally {
try {
if (c != null) c.close();
if (is!= null) is.close();
}catch (IOException ioex){
mc.messaggio(ioex.toString(),this.mm,0);
}
return strData;
}
}



The code is invoked by a different thread and i've also tried to put a Thread.sleep(1000) method before communication begin as reported in others thread in forum.

ANY IDEA????
Thanks a lot.

hi stefanogalizia,

welcome to Nokia forum.

Nokia 6680 and 6630 (updraded version only) will not support InputStream properly.

Hi l_satyadev, thanks for your response but problem still exist. I've tried to use

is = c.openDataInputStream();

instead of

is = c.openInputStream();

but application freeze and never return from the openDataInputStream line...
i don't know what to do... any other idea?

Thanks a lot

Sorry is a stupid question, but are you invoking all your communication code from the running thread or just from a function call? I mean if your communication codes are not running in the thread, then it could be the reason for deadlocks.

I've tried both... running in a separate thread and in the main thread (a function call)... both methods not works.

any other ideas????? Thx

hi,

#1
what is your response code?
#2
can you test behavior with some public domain and simply post which one someone else (say me) could try to recreate?

thanks,
regards,
Peter

Hi peter,

#1 I don't receive response code, just freeze the application even if i try to read the response code
#2 This is the url which try to connect..You can test if you receive the text stream

Let me know

Thank you.

HI to all, thanks for youre responses. I've got the SOLUTION, yeah!

I just deleted all APN and configured the one i use to connect to internet and everything goes ok. I think theres some bug in the implementation of some JAVA API because after i've deleted some APN when i try to connect phone ASK me to select APN (first this behavior does not occurs).


Thx to all.

Hi Stefano,
I've also some strange behaviours when using connections here in Italy.
It works fine with internet connections but not with wap ones.
Do you ever tested both for your application ?

[stefanogalizia]

Yes i've used TIM WAP profile and everything goes right!

[thecloud]

could you please post the connection routine you are using ?
I've tested a couple but can't figure out what's wrong because mine works with internet connection but not with wap connection.

[stefanogalizia]

if you look at the first post in this thread you can see the code..

[thecloud]

Yes thanks, I've tryed that and I get the same exact problems.
Actually I've written a little logger and on the internet connection everything works fine but with the NOK9500 I get an exception like:
"Symbian OS error = -36"
while with NOK7710 I get:
"Symbian OS error = - 17210"

This really s**ks

Yes i've used TIM WAP profile and everything goes right!

On note: With Vodafone (I haven't tested Tim yet on this) I've changed the Access Point Name to "web.omnitel.it" from the previous "wap.omnitel.it" and everything works, so it's really something related to the apn then.
I've left all proxy stuff untouched and works.

Are you really sure you are using the TIM WAP with "wap.tim.it" as APN and not changed to "ibox.tim.it" ?
