Question

我使用visual studio创建了一个Web服务并对其进行了测试，它运行正常。我试图从eclipse调用web方法。我没有得到任何错误，但问题是没有任何反应。它应该将从用户获取的值插入数据库。我已经给出了下面的java类和web方法。我究竟做错了什么？请帮忙

////用于调用传递值/////

的Web方法的Java类

public class Registration extends Activity{
private static final String SOAP_ACTION = "http://tempuri.org/register";

private static final String WSDL_TARGET_NAMESPACE = "http://tempuri.org/";
private static final String SOAP_ADDRESS = "http://10.0.2.2:54714/WebSite1/Service.asmx";

Answer 1

感谢某人，我发现了什么问题。

1）我用过：

AndroidHttpTransport androidHttpTransport = new AndroidHttpTransport(SOAP_ADDRESS);

相反它应该是：

HttpTransportSE httptransport = new HttpTransportSE(SOAP_ADDRESS);

2）我用过：

            PropertyInfo pi = new PropertyInfo();
            pi.setName("fname");
            pi.setValue(firstname);
            pi.setType(int.class);
            Request.addProperty(pi);

相反它应该是：

request.addProperty("fname", String.valueOf(firstname));

对于其他文本字段

使用KSOAP2从eclipse调用web方法
