                    out.write(buffer, 0, numRead);

Check the response headers. You can use [URLConnection#getHeaderField()|http://java.sun.com/javase/6/docs/api/java/net/URLConnection.html#getHeaderField(java.lang.String)] for this. It may be available in the [content-disposition|http://www.w3.org/Protocols/rfc2616/rfc2616-sec19.html#sec19.5.1] header.
