关于webserber获取数据的问题

[xin_zzq1]

          SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
    	   SoapEnvelope.VER11);
    	   envelope.bodyOut = rpc;
    	   (new MarshalBase64()).register(envelope);
    	   HttpTransportSE ht = new HttpTransportSE("url");

    	   ht.debug=true;
    	   ht.call(ur+"/get_Info", envelope);
            Object info = (Object)envelope.getResponse();

我能够成功获取到数据，但是webserver传送的是map数据，怎么把Object info转车成map数据
