inputStream.available();
This is what I'm trying to do,I want to send image byte[] from a J2ME client to a servlet.But there is no correct length returned.Is there any way can get through this?I heard some one use Printwriter works,but still not work in my case.
on servlet side--
String type=request.getContentType();
int length=request.getContentLength();
videoStream =request.getInputStream();
// int length=0;
// streamBuffer=new byte[videoStream.available()];
// videoStream.readLine(streamBuffer,0,videoStream.available()/4);
// length+=streamBuffer.length;
// byte[] image = streamBuffer;
response.setContentType("text/plain");
String ImageID = request.getParameter("ImagID");
PrintWriter pw = response.getWriter();
pw.write("POST received image package of size "+videoStream.available()+"\n");
// pw.write("length read in the buffer is "+ length+"\n");
pw.write("The image name passed in the parameter is "+ImageID);
pw.close();
-J2ME side
try{
String thisURL=url+"?ImagID=" + "1.jpg";
httpConnection=(HttpConnection)Connector.open(thisURL);
httpConnection.setRequestMethod(HttpConnection.POST);
httpConnection.setRequestProperty("User-Agent",
"Profile/MIDP-2.0 Configuration/CLDC-1.0");
httpConnection.setRequestProperty("Content-Language", "en-US");
// out= new DataOutputStream(httpConnection.openDataOutputStream());
byte[] sendData=null;
sendData=midlet.raw;
int[] sendInt=null;
sendInt=getIntArray(sendData);
pw=new PrintWriter(httpConnection.openOutputStream());
for(int i=0;i<sendInt.length;i++)
pw.write(sendInt);
//for (int i=0; i><sendData.length; i++)
//out.writeByte(sendData);
pw.flush();
pw.close();
//out.flush();
// out.close();
int responseCode = httpConnection.getResponseCode();
if (responseCode != HttpConnection.HTTP_OK)
throw new IOException();
InputStream is = httpConnection.openInputStream();
data = readReplyBody(httpConnection, is);
String message = new String(data, 0, data.length);
System.out.println("Response from servlet "+message);
is.close();
}
catch (ConnectionNotFoundException e)
{
Alert alert = new Alert("No Handler for HTTP", e.toString(),
null, AlertType.ERROR);
alert.setTimeout(Alert.FOREVER);
midlet.getDisplay().setCurrent(alert);
}
catch (IOException e)
{Alert alert = new Alert("IO Error", e.toString(),
null, AlertType.ERROR);
alert.setTimeout(Alert.FOREVER);
midlet.getDisplay().setCurrent(alert);
