permission denied:connect when reading an image attachment from java

[Gregory Hamel]

I'm testing couchDb for use in my java app and I can't seem to read document
attachments using plain old Java http.

I have a good understanding of couch and for this test I've setup a new
dbase with a single doc having a single image attached. I can get the image
from couch using a browser and using curl, both without authentication, so I
know that my uri is correct and I know there is no security on the dbase.

However.. When I try to read the image using java i get a permission denied
exception at the socket level and the Erlang console (ya its windoze)
doesn't log anything at all. Yet this code *will* pull an image from another
website.

Is there some additional header that I need to setup on my connection before
connecting?

Here's the relevant portion of my code and the resulting stacktrace..

  // this fails
  try {
          URL u = new URL("http://192.168.1.7:5984/test/img/jv0h.jpg";);
          HttpURLConnection conn = (HttpURLConnection)u.openConnection();
          conn.setRequestMethod("GET");
          conn.connect();
          image1 = ImageIO.read(conn.getInputStream());
    } catch (IOException e) {
        e.printStackTrace();
    }

    // and this fails
    try {
        URL url2 = new URL("http://192.168.1.7:5984/test/img/jv0h.jpg";);
        image2 = ImageIO.read(url2);
    } catch (IOException e) {
        e.printStackTrace();
    }

    // but this works
    try {
        URL url2 = new URL("http://java.com/images/jv0h.jpg";);
        image3 = ImageIO.read(url2);
    } catch (IOException e) {
        e.printStackTrace();
    }
