Receiving image using socket connection in midlet

see here is my server code:

ServerSocket s=new ServerSocket(5000);

Socket c=s.accept();

String fileName = "C://duke.png";

FileImageInputStream input = new FileImageInputStream(new File(fileName));

ByteArrayOutputStream output = new ByteArrayOutputStream();

PrintWriter p=new PrintWriter(new OutputStreamWriter(c.getOutputStream()),true);

byte[] buf = new byte[(int)input.length()];

byte[] data = null;

int numBytesRead = 0;

while ((numBytesRead = input.read(buf)) != -1) {

output.write(buf, 0, numBytesRead);

}

data = output.toByteArray();

System.out.print(data);

p.print(data);

output.close();

input.close();

p.close();

s.close();

*************client code***********

ByteArrayOutputStream bStrm=null;

try {

sc = (SocketConnection) Connector.open("socket://localhost:5000");

DataInputStream dis=sc.openDataInputStream();

int len=dis.available();

imgData=new byte[len];

os = sc.openOutputStream();

int s=0;

int c;

String ss;

// Loop forever, receiving data

bStrm=new ByteArrayOutputStream();

c = 0;

while ((c=dis.read())!=-1)

{

bStrm.write(c);

}

imgData = bStrm.toByteArray();

System.out.println(imgData);

bStrm.close();

// Form Screen;

img=Image.createImage(imgData,0,imgData.length);

} catch (ConnectionNotFoundException cnfe) {

Alert a = new Alert("Client", "Please run Server MIDlet first",

null, AlertType.ERROR);

a.setTimeout(Alert.FOREVER);

a.setCommandListener(this);

} catch (IOException ioe) {

if (!stop) {

ioe.printStackTrace();

}

} catch (Exception e) {

e.printStackTrace();

}

*******************

but it throws sometimes ArrayOutOfBound or IllegalArgumentException. pls help.

Hi,

Sending the data from server through PrintWriter.print(Object) doesn't look good. It seems, that it will only send Object.toString() instead of you array. try to use OutputStream instead.

You can even get rid of intermidiate buf[] variable and do like the following:

OutputStream os=c.getOutputStream();

int numBytesRead = 0;

while ((numBytesRead = input.read(buf)) != -1) {

os.write(buf, 0, numBytesRead);

}
