HttpConnection.openInputStream() blocks forever

[besbello]

I do this in a Nokia 6233 (only in real device, in emulator I have not problem):

HttpConnection conn = (HttpConnection)Connector.open(url);
InputStream is = conn.openInputStream();

I want to get the data from HttpConnection while the data is being downloaded, a streaming of images using mjpeg. But openInputStream blocks forever. I make other connections the same way without problem, but these connections are not "permanent", and are closed quickly.

Could anybody help me, please

hi,

have you checked what response code goes from server when requesting that kind of content?
are you sure that openInputStream() is in deadlock not your byte data processing routine?

regards,
peter

I don't know if this relates or not, but this is what I normally do and worked for me: Try getting the OutputStream and close() it first... this flushes things, then open the inputstream you want.



c = (HttpConnection)Connector.open(hostURL);

.
.
set request method and properties
.
.

OutputStream os = c.openOutputStream();

//write anything you need to the OutputStream, if needed

os.close();
os = null;

InputStream is = c.openInputStream();


Something like that... Please try.

peterblazejewicz: I can't check response code, because I don´t get any response at client midlet. The only way to get anything is closing connection at server side. Yes, I'm sure openInputStream() is waiting forever.

ykasidit: I've tried your solution, but it doesn't work for me. I have the same problem when trying to open outputStream (conn.openInputStream(), applications blocks in this sentence). I've also tried outputstream.flush at, server side, but no success. The only way to release blocking at client is closing output stream at server side.

Any more help would be appreciated
Thanks both of you

You must use HttpConnection.openDataInputStream() instead of openInputStream(). Had exact same problem and this fixed it on nokia series 60 2nd edition devices.
