Apache http クライアントを使用して WS をテストしています。get WS in jersey を書きました。このWSのURLは
http://localhost:8080/mobilestore/rest/sysgestockmobilews/getinventory?xml=dataString
URLを使用してこのWSを呼び出すには、次のようなメソッドを作成しました
public static void getInventory(String input)
throws ClientProtocolException, IOException {
System.out.println(input);
String url = URL + "getinventory";
HttpClient client = new DefaultHttpClient();
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
nameValuePairs.add(new BasicNameValuePair("xml", input));
String paramString = URLEncodedUtils.format(nameValuePairs, "utf-8");
url += "?" + paramString;
System.out.println(url);
HttpGet request = new HttpGet(url);
HttpResponse response = client.execute(request);
BufferedReader rd = new BufferedReader(new InputStreamReader(response
.getEntity().getContent()));
String line = "";
while ((line = rd.readLine()) != null) {
System.out.println(line);
}
}
プログラムを実行してこの関数にURLを渡すと、次の行で例外が発生します
HttpResponse response = client.execute(request);
例外は次のとおりです

ここで、WS URL を使用して任意のブラウザを使用してヒットすると、期待どおりの結果が得られますが、Apache http クライアント コードの何が問題なのかを知りたい..
