我必须开发一个 android 应用程序。该应用程序执行从 mysql 数据库中检索数据并显示在 android 模拟器和 android 设备上。

首先,我必须在 localhost 上设置 tomcat 服务器并在 localhost 上运行这些 wsdl 文件,这意味着检索数据已成功显示在模拟器和 android 设备上。

另外我必须在远程设置tomcat服务器。在这里我上传了我的war文件并获取了wsdl文件。现在我必须放置这些wsdl URL意味着在我的模拟器和android设备上都出现黑屏。

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();

我必须把这个网址

private static final String URL = "10.0.0.133:8089/TestPrompts/services/Fetch?wsdl";

意味着正在检索数据。这个 wsdl 文件在 localhost 的 Tomcat 服务器上运行。

但我必须把这些网址的意思

private static final String URL = "87.76.29.180:8080/TestPrompts/services/Fetch?wsdl";

这次只是在错误之上。这个 wsdl 文件在远程的 Tomcat 服务器上运行。

尝试使用 AndroidHttpTransportSE 代替 HttpTransportSE 并在创建信封后添加此语句。信封.dotNet=真;

为了获得更好的结果,请查看本教程

我相信你没有得到原始类型。尝试这个:

SoapObject response = (SoapObject)envelope.getResponse();

请参阅:尝试构建正确的 SOAP 请求

我得到了解决方案。因为我的数据库只有静态权限..我必须授予访问数据库全局权限意味着它运行良好。
