在Java中调用大型URL

如何在Java中调用大型URL?我正在将scene7图像服务器与java应用程序集成。这里我调用了一个大约10000个字符的URL,它应该会返回一个图像。我可以用什么方法做到这一点?

我的写作方式是-

URL oURL= new URL("<*LONG LONG URL - approx. 10k characters*>");
HttpURLConnection connection = (HttpURLConnection) oURL.openConnection();
InputStream stream = connection.getInputStream();
int len;
byte[] buf = new byte[1024];
BufferedImage bi = ImageIO.read(stream);
ImageIO.write(bi,"png",response.getOutputStream());  

while ((len = stream.read(buf)) > 0) {
    outs.write(buf, 0, len);
}
