java - axis2 応答を置き換えます

Question

以前は、xml ファイルを読み取って応答として返す軸を使用して、Web サービス用のハンドラーを 1 つ実装していました。私のコードは以下の通りです：

try {
        Message msg = msgContext.getResponseMessage();
        MessageContext context = MessageContext.getCurrentContext();



        InputStream in = this.getClass().getClassLoader().getResourceAsStream("login_rsp_xml");
        if(in==null){

            System.out.println("in is empty!!!");
        }
        DocumentBuilderFactory dbFactory = DocumentBuilderFactory
                .newInstance();
        DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
        Document doc = dBuilder.parse(in);
        msg.getSOAPPart().setContent(new DOMSource(doc));
        System.out.println("return file>>"+fileName);

    } catch (Exception e) {
        System.setProperty("req_no", null);
        e.printStackTrace();            
    }

今度は、axis2 を使用して同じことを行う必要があります。axis2 の発信応答を置き換える方法を知っている人はいますか? ファイルを文字列に変換し、envelope.setText() を呼び出そうとしましたが、失敗して例外 " org.apache.axiom.soap.SOAPProcessingException: Can not detach SOAP Body, SOAP Envelope must have a Body !!" が発生しました。

ヘルプ/アドバイスをよろしくお願いします。
