Re: POSTing to a servlet

I have a JUnit test that tests a servlet. The code is straightforward:

HttpClient httpClient = new DefaultHttpClient();
List<NameValuePair> nvps = new ArrayList<NameValuePair>();
HttpPost httpPost = new HttpPost("http://myaerver.com:8080/servlets/json");
addParameter(nvps, "query", "engagementByFacility");
addParameter(nvps, "surveyId", 681150);
httpPost.setEntity(new UrlEncodedFormEntity(nvps));
ResponseHandler<String> responseHandler = new BasicResponseHandler();
String responseBody = httpClient.execute(httpPost, responseHandler);

On this last line however, httpClient.execute(), things fail and I am at an utter loss as to why. The URL is good. Examination of the stack shows:

org.apache.http.client.HttpResponseException: Moved Temporarily

"Moved Temporarily?" What in the world might be going on here? TIA
