Java Ksoap2响应存在问题

嘿，大家好，我在ksoap2上遇到了一个小问题，并且得到了响应。我在Blackberry客户端上有以下代码：

private boolean AddVoiceNote()
{
    _webMethod = "AddVoiceNote";
    _soapAction.concat(_webMethod);
    Boolean response = null;

    SoapObject methodCall = new SoapObject(_serviceNameSpace, _webMethod);
    SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

    soapEnvelope.bodyOut = methodCall;
    soapEnvelope.dotNet = false;
    soapEnvelope.encodingStyle = SoapSerializationEnvelope.XSD;
    soapEnvelope.setOutputSoapObject(methodCall);

    methodCall.addProperty("name", _voiceNote.get_nombre());
    methodCall.addProperty("comment", _voiceNote.get_comentario());
    methodCall.addProperty("audio", Base64.encode(_voiceNote.get_audioArray()));
    methodCall.addProperty("id", String.valueOf(_voiceNote.get_userId()));
    methodCall.addProperty("postTwitter", String.valueOf(_voiceNote.is_twitterPost()));
    methodCall.addProperty("postFacebook", String.valueOf(_voiceNote.is_facebookPost()));

    HttpTransport transport = new HttpTransport(_serviceURL);

    transport.setXmlVersionTag("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
    try {

        transport.call(_soapAction, soapEnvelope);
        SoapObject responseSoap = (SoapObject)soapEnvelope.getResponse();
        response = (Boolean)responseSoap.getProperty("return");
        System.out.println(responseSoap.toString());
        return response.booleanValue();
    } catch (IOException e) {
        return false;
    } catch (XmlPullParserException e) {
        return false;
    }

}

我遇到的问题是正确地获取响应，我在尝试获取它时得到一个ClassCastException，调试器只是退出了该方法，你知道如何修复这个问题吗？哦，下面是我从Web方法得到的响应xml：

<?xml version='1.0' encoding='UTF-8'?>
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
 <S:Body><ns2:AddVoiceNoteResponse xmlns:ns2="http://WebService/">
  <return>true</return></ns2:AddVoiceNoteResponse>
 </S:Body>
</S:Envelope>

真的

对不起，我没有写评论的特权，否则我不会为这个小提示发布答案

实际上，信封有一个方法“stringToBoolean”

问候语

什么是ClassCastException？发生在这一行SoapObject ResponseSAP=（SoapObject）soapEnvelope.getResponse（）；只是说ClassCastException在将强制转换从SoapObject更改为Object y之后，请注意getResponse（）为null，现在我尝试了：（soapEnvelope.getResponse（））.toString（）并得到了表示“true”的字符串，但是如果我想要实际的布尔值呢？因为在eclipse中，由于某些原因，我无法执行Boolean.getBolean（string）或.valueOf（string）

<?xml version='1.0' encoding='UTF-8'?>
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
 <S:Body><ns2:AddVoiceNoteResponse xmlns:ns2="http://WebService/">
  <return>true</return></ns2:AddVoiceNoteResponse>
 </S:Body>
</S:Envelope>
