我必须开发一个 android 应用程序。该应用程序执行从 mysql 数据库检索数据并显示在 android 模拟器和 android 设备上。
首先，我必须在本地主机上设置 tomcat 服务器，并在本地主机上运行这些 wsdl 文件，这意味着获取的检索数据已成功显示在模拟器和安卓设备上。
此外，我还必须在远程设置 tomcat 服务器。我已经上传了我的 war 文件并获取了 wsdl 文件。现在我必须输入这些 wsdl URL，这意味着我的模拟器和 android 设备上都会出现空白屏幕。
我的控制台窗口显示以下错误:

我该如何解决这个错误。请帮助我。
这是我的代码:
public class RetailerActivity extends Activity {
private static final String SOAP_ACTION = "http://ws.testprops.com/customerData";
private static final String METHOD_NAME = "customerData";
private static final String NAMESPACE = "http://ws.testprops.com";
//private static final String URL = "http://10.0.0.133:8089/TestPrompts/services/Fetch?wsdl";
private static final String URL = "http://87.76.29.180:8080/TestPrompts/services/Fetch?wsdl";
/*
private static final String SOAP_ACTION = "http://xcart.com/customerData";
private static final String METHOD_NAME = "customerData";
private static final String NAMESPACE = "http://xcart.com";
private static final String URL = "http://10.0.0.133:8089/XcartLogin/services/Fetch?wsdl";*/
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
HttpTransportSE ht = new HttpTransportSE(URL);
try {
ht.call(SOAP_ACTION, envelope);
SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
SoapPrimitive s = response;
String str = s.toString();
String resultArr[] = str.split("&");//Result string will split & store in an array
TextView tv = new TextView(this);
for(int i = 0; i<resultArr.length;i++){
tv.append(resultArr[i]+"\n\n");
}
setContentView(tv);
} catch (Exception e) {
//Log.e("Error : " , "Error on soapPrimitiveData() " + e.getMessage());
e.printStackTrace();
}
}
}
这是我的第 36 行:
SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
我必须把这个 url
private static final String URL = "10.0.0.133:8089/TestPrompts/services/Fetch?wsdl";
表示正在检索数据。此 wsdl 文件在位于本地主机的 tomcat 服务器上运行。
但我必须将这些 url 表示为
private static final String URL = "87.76.29.180:8080/TestPrompts/services/Fetch?wsdl";
这次只是出现以上错误。此 wsdl 文件在 远程 tomcat 服务器 上运行。
最佳答案
我相信您得到的不是原始类型。 试试这个:
SoapObject response = (SoapObject)envelope.getResponse();
