Hugh,
I'm calling the API from within the Java framework, here is the code:
HttpURLConnection c = null;
> try {
>
> URL url = new URL(Proxy.ENDPOINT_FACETS);
> c = (HttpURLConnection) url.openConnection();
> c.setRequestMethod("POST");
> c.setRequestProperty("Content-Type", "text/xml;
> charset=\"UTF-8\"");
> // c.setRequestProperty("Content-Type", "text/xml");
> c.setDoOutput(true);
> // OutputStreamWriter out = new
> OutputStreamWriter(c.getOutputStream(), "UTF8");
> System.out.print("Query xml string: ");
> System.out.println(document.toString());
> document.output(c.getOutputStream()); // takes stream or
> printwriter
> // out.write(xmlText);
> c.getOutputStream().close();
>
> DataInputStream input = new
> DataInputStream(c.getInputStream());
>
Error occurs at the last line there when I get the response from the server.
I get 500 and 501 errors now 100% of the time. Are you tracing the responses
you send back to client? Here's what I get:
