我发布了一个webservice服务，在手机模拟器里调用使用ksoap,但是ksoap包找不到，这是什么原因呢，怎么配置Ksoap呢，调用如下：

  SoapObject rpc = new SoapObject
    ("http://localhost:7001/web-services/getName", "process");

      rpc.addProperty("name", "aa");
      rpc.addProperty("pass", "aa");
      HttpTransport ht = new HttpTransport
    ("http://localhost:7001/web-services/getName", "");

      result = (String) ht.call(rpc);



错误提示

"getNameStub.java": cannot find symbol; symbol  : class SoapObject, location: class mobile.getNameStub at line 15, column 28
