HTTP Problem on series 40

[manupeco]

Hi,
I'm having a problem executing a series of HTTP posts using Nokia series40 (Nokia 5310 XPress Music and Nokia Emulator series 40 5th edition).

After a number of request ok (where I can also read correctly the response of the server) I get this error:

java.io.IOException:
at com.nokia.mid.impl.isa.io.protocol.internal.wap.Protocol.ensureConnec
ted(+15)

at com.nimbuzz.communication.jabber.JabberHTTP.access$200(+5)
at com.nimbuzz.communication.jabber.JabberHTTP$RequestThread.run(+106)

The code to send the request is:

connection.setRequestMethod( HttpConnection.POST );
connection.setRequestProperty( "Content-Type", CONTENTTYPE );
connection.setRequestProperty( "Connection", "close" );

OutputStream httpOut = connection.openOutputStream();

// write data to stream
httpOut.write( httpRequest.getBytes() );
httpOut.flush();
httpOut.close();


The same code works fin on other phones or emulators.

Anyone has an advice? Did someone experience the same problem?

Hello manupeco,

does this issue happen after certain number of POST requests?

Which other devices are you referring to?

Hi,
Yes, it happens after a certain number of post. The other devices I refer to are: Nokia N80, Sony-Ericsson W850, LG KE-970 for example.

Do you have any idea?

Hello manupeco,

sorry, I meant after how many POSTs this happens?

Are you closing HTTP connection after each POST?

For Series 40, AFAIK if a midlet doesn't call HttpConnection.close(), then the number of connections is limited.

Hi,
Yes, the HTTP connection is closed after each post.

So far, no solution.

Thanks

Hi,
The problem has been solved. After the write there was a part of the code where an XML parsing operation was performed but the InputStream used for this operation wasn't closed after the end of the action.

Adding the needed closing method everything works now.

Thanks for the help
