MS SQL 2008データベースに接続して情報を取得し、結果セットをクラスに渡してjsonarrayに変換し、その情報を返すjavaサーブレットがあります。私はhttp://localhost:8080/KReport/GetInfo?q=va-sql2008を使用して、私のブラウザからクラスを参照するときここJSONArray - javascript（jsp）を使用して表示する方法
は返さ情報のサンプルです：

そこに記載されている2機があります（あなたがそこにmachineinfo検索する場合、あなたは2を見つけますエントリ）。私はJSONLintでこの返された情報を確認し、有効なjsonとしてチェックアウトします。
サーブレットはresponse.getWriter().write(njson.toString());で情報を返しますが、別のページにjavascriptを使用してこの情報を表示する方法を理解できないようです。
私の最後の試みを使用していました：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
</head>
<script type="text/javascript">
$.ajax({
url:'http://localhost:8080/KReport/GetInfo?q=va-sql2008',
dataType:'json',
type:'GET',
success:function(data){
console.log(data);
},
error:function(jxhr){
console.log(jxhr.responseText);
}
});
</script>
</html>
しかし、それは動作しませんでした - ちょうど空白の画面を。
助けていただけたら幸いです。
