Hi,

I'm having issues with a generic JavaME application when opening an https connection on an OS 4.1 device. Using the following code I get an IOException "Input stream already open":

byte[] data = null;
DataInputStream input = null;
DataOutputStream output = null;
HttpConnection conn = null;

try {
	conn = (HttpConnection)Connector.open(url);
	input = conn.openDataInputStream();
	output = conn.openDataOutputStream();
	
	data = new byte[input.available()];
	input.readFully(data);
} catch(Throwable t) {
t.printStackTrace();
}

Looking at the stack trace I believe the exception is thrown inside conn.openDataOutputStream();

This works fine on OS 4.2 and up, and changing the url to 'http:' works fine.

Any ideas?

Cheers

Aren't you supposed to use an HttpsConnection with https?

Do you really have to open an output stream ?

HttpsConnection extends from HttpConnection so it shouldn't make a difference.

Not in this example no, but in the real thing yes.

In that case, you CAN'T open the output stream once you have opened the input stream (the output stream is used to post the query parameters!).

Hmm, I'm not sure thats entirely true but either way I checked the code and in one place it doesn't actually use or open the output stream and in the other it opens it first.
