Question

My BlackBerry application should fetch an image from a web service and display the image as a thumbnail. Can anyone give me an idea on how to achieve this?

This code can help you

        connection = (HttpConnection) Connector.open(fullUrl.toString(),
            Connector.READ_WRITE, true);


        InputStream is = hc.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);
        }
        bb = bStrm.toByteArray();

This will generate Byte Array from your web service url. here bb is byte array.

There are two classes that handles image in BB. EncodedImage and Bitmap, both have constructors that generate image from byte array. I recommend use Bitmap, it has easy image re size capability.
