get image from bytes blackberry - blackberry

Question

I am developing a blackberry application which retrieves image from the server , some of images are being retreived and other give error in the encodedImage Line
ImageFromUrl _img = new ImageFromUrl(item.getThumbLink());
byte[] bytes = _img.getbitmap();
Bitmap newBitmap = new Bitmap(width, fieldHeight);
if (bytes != null) {
// bitmap = Bitmap.createBitmapFromBytes(bytes, 0,
// bytes.length, Bitmap.SCALE_TO_FIT);
EncodedImage image = EncodedImage.createEncodedImage(bytes,
0, bytes.length);
}
and that's the connection which get the bytes
ImageFromUrl(String url) {
this.url = url;
}
public byte[] getbitmap() {
try {
connection = (HttpConnection) Connector.open(
url + Connection.getBlackBerryConnectionParams(),
Connector.READ, true);
InputStream is = connection.openInputStream();
DataInputStream dis = new DataInputStream(is);
ByteArrayOutputStream bStrm = new ByteArrayOutputStream();
int ch;
while ((ch = dis.read()) != -1) {
// System.out.println((char) ch);
// msg = msg + (char) ch;
bStrm.write(ch);
}
dataArray = bStrm.toByteArray();
} catch (IOException e) {
e.printStackTrace();
}
return dataArray;
}
how can I solve that to get all images without errors ?

Try this code:
public Bitmap getBitmapFromUrl(String url)
{
Bitmap bitmap=null;
try
{
HttpConnection connection=(HttpConnection)Connector.open(url);
connection.setRequestMethod(HttpConnection.GET);
InputStream is=connection.openInputStream();
int length=is.available();
byte[] data=new byte[length];
data=IOUtilities.streamToBytes(is);
connection.close();
is.close();
bitmap=Bitmap.createBitmapFromBytes(data,0,data.length,1);
if(bitmap!=null)
return bitmap;
else
return bitmap=Bitmap.getBitmapResource("noimage.png");
}
catch (Exception e)
{
return bitmap=Bitmap.getBitmapResource("noimage.png");
}
}
