I want to send an XML file 633 kb long by POST method
I figure four solutions:

1. compression of the sending data,or decryption : but the client would not like it
2. increase of time out in my pearl or curve device: can't figure it out
3. send data in chunks: is there a way to set no. of chunks and the connection sends that many byte out of the buffer, in the same connection?
4. keep alive HttpConnection settings: don't know I can't go to every client to do that

I have separate thread for separate connections
Please help me how can I do all of them, or any one
Regards

My Code is as follows

PHP Code:

I have the attachment from the etheral from the NetBeans build for BlackBerry application.
I am viewing in JDE version 4.5 and testing in BlackBerry 8100.
I have tried Connection:KeepAlive, but don't know how to send Connection: close
I have tried

mode=Connection.READ_WRITE;(HttpConnection)Connector.open(url,mode,false);

Both are not working

The error it gives is InterruptedIOException,DNS Connection timed out,
The connection should wait for the OutputStream while it is being written.

I have changed the headers to:

PHP Code:

c.setRequestProperty(HttpProtocolConstants.HEADER_CONNECTION, "Keep-Alive");
c.setRequestProperty("Keep-Alive", Integer.toString(600000)); 


The problem description now:

Statistics:
========
Whether you send any file above 5Kb or 7 contacts, (I have not tested below this and except 1 contacts);

Whatever request it is (we have registration API available to test in and we have tested in it).

The Time-Out Error comes exactly at 3.07 minutes.

The response is never reached neither 200 Ok_ready_to_receive_the_response section.

I think now sombody can help up getting this clear picture
Regards

PHP Code:

/**
*private final String urlPostFix = ";connectionuid=wap2 trans;deviceside=true";

*private final String urlPostFix = ";connectionuid=wap2 trans;deviceside=true;wapgatewayapn= blackberry.net";

*private final String urlPostFix = ";connectionuid=wap2 trans;wapgatewayapn=airtelfun.com;deviceside=true";
**/

private final String urlPostFix = ";connectionuid=wap2 trans;wapgatewayport=9201;wapgatewayip=100.1.200.99;wapgatewayapn=blackberry.net;deviceside=true"; 


I have used the above string one by one to test connections as postFix to the url but got no success.

You have to specify correct APN, gatway and port.
You should always have "User-Agent" request header in the Connection code and in the property of "User-Agent" you should have the name of the device say "Pearl".
