Error in downloading .gif image

Question

hi frndz
I am writing an application which downloads the image from server
for .jpeg, .jpg, .png its working fine but for .gif images it gives me the error: ArrayIndexOutOfBoundException
Code for downloading Image is:
ContentConnection connection = (ContentConnection) Connector.open(url);
DataInputStream iStrm = connection.openDataInputStream();
// two methods are used to download IMAGE
// (I) If length available , (II) If length not available
int length = (int) connection.getLength();
// (Method I :) ContentConnection includes a length method
if (length != -1)
imageData = new byte[length];
iStrm.readFully(imageData);
// (Method II :) If Length not available...
else
ByteArrayOutputStream bStrm = new ByteArrayOutputStream();
int ch;
while ((ch = iStrm.read()) != -1) bStrm.write(ch);
imageData = bStrm.toByteArray();
if (bStrm != null) bStrm.close();
// Create the image from the byte array
img = Image.createImage(imageData, 0, imageData.length-1);
When I print Image length its zero and also imageData length is zero
is there any other method to download .gif images
thanks

Answer 1

the problem is not in displaying image
and by the way i am testing this on N70
problem is in downloading
i.e. image length is zero as well asif I dont consider image length the downloaded bytes are zero
