我在一个Android项目中工作，我想要使用一些JAX-WS。这些服务是由其他人制作的，所以我无法改变它们的任何内容。我想用这个编写的代码发送上面的SOAP消息，但是在调用它们时我唯一收到的是java.lang.NullPointerException
private static final String NAMESPACE = "http://poweb13/";
private static final String URL = "http://smart.gr:8080/aWESoME/SmartPlugService?wsdl";
private static final String SOAP_ACTION = "SmartPlugService";
private static final String METHOD_NAME = "FReadStatus";
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
PropertyInfo p1 = new PropertyInfo();
p1.setName("MAC");
p1.setValue("000D6F0000");
p1.setType(myDevice.getmac().toString().getClass());
request.addProperty(p1);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
try {
androidHttpTransport.setXmlVersionTag("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapObject resultsRequestSOAP = (SoapObject) envelope.bodyIn;
String result=resultsRequestSOAP.getProperty("return").toString();
Log.i("info","Received :" + result);
} catch (java.lang.ClassCastException e){
SoapFault fault=(SoapFault)envelope.bodyIn;
Log.e("error","Received :" + fault.getMessage().toString());
Log.e("error","Received :" + fault.getLocalizedMessage().toString());
StackTraceElement[] st=fault.getStackTrace();
for(int i=0;i<st.length;i++){
Log.e("error","Received :" +st[i] );
}
} catch (Exception e) {
Log.e("error","smthing went wrong!!");
e.printStackTrace();
}
我认为它甚至没有创建xml文档，但我不知道如何检查它。我试图创建一个XmlSerializer来放置数据来创建xml，但我也收到一个NullPointerException。 那么有人可以帮我解释如何编写上述请求吗？ 这是wsdl文件的一些部分

xsd文件的某些部分
<xs:schema xmlns:tns="http://poweb13/" xmlns:xs="http://www.w3.org/2001/XMLSchema" version="1.0" targetNamespace="http://poweb13/">

<xs:complexType name="FReadStatus">
<xs:sequence>
<xs:element name="arg0" type="xs:string" minOccurs="0"/>
</xs:sequence>
</xs:complexType>
我应该有这样的SOAP响应：
SOAP Response
<?xml version="1.0" encoding="UTF-8"?>
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
<S:Body>
<ns2:FReadStatusResponse xmlns:ns2="http://poweb13/">
<return>1</return>
</ns2:FReadStatusResponse>
</S:Body>
</S:Envelope>
答案 0 :(得分：2)
好的，你有一个功能FReadStatus：
<message name="FReadStatus">
<part name="parameters" element="tns:FReadStatus"/>
</message>
其中 FReadStatus 复杂类型（即对象，它是在服务器上找到的类）。
此复杂类型具有String类型的属性 arg0 。它的定义是：
<xs:complexType name="FReadStatus">
<xs:sequence>
<xs:element name="arg0" type="xs:string" minOccurs="0"/>
</xs:sequence>
</xs:complexType>
因此，您需要创建一个实现 kvmSerializable 的本地类，以将此复杂类型映射到服务器上的相应类，因此您将执行以下操作：
public class FReadStatus implements KvmSerializable {
String mac;
@Override
public Object getProperty(int arg0) {
switch (arg0){
case 0:
return mac;
default:
return null;
}
}
@Override
public int getPropertyCount() {
return 1;//because you have 1 parameter
}
@Override
public void getPropertyInfo(int arg0, Hashtable arg1, PropertyInfo arg2) {
switch(arg0)
{
case 0:
arg2.type = PropertyInfo.STRING_CLASS;//because its type is string
arg2.name = "arg0";
break;
default:break;
}
}
@Override
public void setProperty(int arg0, Object arg1) {
switch(arg0)
{
case 0:
mac= (String)arg1;
break;
default:
break;
}
}
现在你有了这个课程，你将在你的代码中执行以下操作：
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
PropertyInfo pi = new PropertyInfo();
pi.setName("arg0");
pi.setValue("000D6F0000");
pi.setType(FReadStatus .class);
request.addProperty(pi);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
//Now you have to add mapping to map the local class created, to the one on the server
envelope.addMapping(NAMESPACE , FReadStatus.class.getSimpleName(), FReadStatus .class);
// Add marshalling (this one might not be necessary, but ill just add it)
Marshal floatMarshal = new MarshalFloat();
floatMarshal.register(envelope);
AndroidHttpTransport androidHttpTransport = new AndroidHttpTransport(URL);//AndroidHttpTransport INSTEAD OF HttpTransportSE
androidHttpTransport.debug = true;//NEW ADDED
try {
androidHttpTransport.call(SOAP_ACTION, envelope);
//Important Outputs to check how the request/Response looks like.. Check them in Logcat to find these outputs
System.out.println("requestDump is :"+androidHttpTransport.requestDump);
System.out.println("responseDump is :"+androidHttpTransport.responseDump);
System.out.println("response"+envelope.getResponse());
} catch (Exception e){}
让我知道wt发生了。您必须使用Logcat来检查requestDump和responseDump
