Reading and Writing Image through Socket

Question

hi
i'm doing a mobileapplication and i send the Image from the server using a DataOutputStream. I'm converting the Image to a byteArray. The Image in .png format. But i need to read it from a J2ME application and when i read the byteArray and convert it to a Image it gives a illegalArgumentException coz it says that cannot decode the Image.
Can anyone Help

Answer 1

some png files are not standard png files thats why u may get the error but u should try like this:
Server side=>
OutputStream os=c.getOutputStream();
int numBytesRead = 0;
while ((numBytesRead = input.read(buf)) != -1) {
os.write(buf, 0, numBytesRead);
Client side=>
bStrm=new ByteArrayOutputStream();
c = 0;
while ((c=dis.read())!=-1)
bStrm.write(c);
imgData = bStrm.toByteArray();
bStrm.close();
img=Image.createImage(imgData,0,imgData.length);
