J2ME: Recording AV and sending to a Server14/04/06 PermalinkFor this to work you will need a servlet supporting server and a phone capable of capturing audio/video/images from Java. You could use this for instance with the Sony Ericsson K700i for sending an image because it supports capture=image/jpeg. Check the Calibrator to see what phones support what capture methods.
Client
//baos is the ByteArrayOutputStream that contains the binary data
//You can usually attach this stream to the Control (VideoControl/RecordControl)
//of Manager.createPlayer(... or with images getSnapShot(encoding)
c = (HttpConnection) Connector.open(uploadURL,Connector.READ_WRITE);
c.setRequestMethod(HttpConnection.POST);
os = c.openDataOutputStream();
byte[] data = baos.toByteArray();
baos.reset();
baos = null;
os.writeInt(data.length); //AA
os.write(data); //BB
os.flush();
Server
DataInputStream dis = new DataInputStream(request.getInputStream());
int filelen = dis.readInt(); //AA
byte[] data = new byte[filelen];
dis.readFully(data); //BB
There's a fuller example here. |
