Help - J2ME implementation in BlackBerry -> http

Hi,

I tested this code in blackberry handeld:

======================
httpCon = (HttpConnection)Connector.open(http://server:8080
/sync4j/sync;WAPGatewayIP=x.x.x.x;WAPGatewayAPN=so
mething;WAPGatewayPort=9201");

httpCon.setRequestMethod(HttpConnection.POST);
httpCon.setRequestProperty("content-length" ,
String.valueOf(dataToSend.length) );
httpCon.setRequestProperty ("content-type" ,
"application/vnd.syncml+xml");

System.out.println("debug ------------->>>>>> 2-content length:" +
String.valueOf(dataToSend.length));

outputStream = httpCon.openDataOutputStream();

System.out.println("debug ------------->>>>>> 3");

outputStream.write(dataToSend);

System.out.println("debug ------------->>>>>> 4");

inputStream = httpCon.openDataInputStream();

System.out.println("debug ------------->>>>>> 5");

int size = (int)httpCon.getLength();

System.out.println("debug ------------->>>>>> 6");

====================================

but if length of dataToSend byte array is larger then 1385 byte, code
some
time crashes at
inputStream = httpCon.openDataInputStream(), and some time code works
well.
It's very strange..... (connection timeout?)
However, if length of dataToSend byte array is less then 1385 byte,
code
works fine.

This is the output of JDE debug attached 7230 handleld:

 ========================================

CMM: SyncContact no sig from 0x33
debug ------------->>>>>> 2-content length:1385
debug ------------->>>>>> 3
debug ------------->>>>>> 4

Later I change
"outputStream.write(dataToSend);"

in

"for (int i = 0, l=dataToSend.length; i < l; i++) {
outputStream.write(dataToSend<i> );
outputStream.flush();
}

outputStream.close();
outputStream = null;"

but it works at the same way.

I can't understand....
Connection Buffer? Connection Timeout?

Thanks & thanks & thanks....
for any suggestion.
